A Hypermedia Approach to James Joyce's "Finnegans Wake" BIBAK 3
  Risto Miilumaki
The application consists of the "Anna Livia Plurabelle" chapter of James Joyce's last novel "Finnegans Wake" (1939) and the manuscripts and French and Italian translations of that text published in Joyce's lifetime. Included is also the gramophone reading by Joyce of the last three pages of the chapter, and facsimiles of the corresponding manuscript pages. A hypertextual and hypermedia approach is well suited to demonstrate the development and the complexities of the text and help the reader better grasp the subtleties of Joycean art. An electronic medium would also be a flexible alternative to traditional, heavy editions of classic texts.

DynaText at Hypertext'93 BIBA 3
  Gregory Lloyd
The Problem: Navigating information online: providing effective features and visual cues for navigation information in a new medium that takes advantage of familiarities with traditional printed information access paradigms.
   What Was Done: Automatic hypertext Table of Contents generation from document hierarchy elements. Inline "hot-text" navigation elements defined to replace printed footnotes. On-the-fly text formatting. Navigation history journals to provide sense of document "locality" online and to support task-oriented navigation (CBT).
   Why the Work is Important: DynaText is the only online information retrieval product to take ISO-compliant SGML data from arbitrary DTDs as the direct input stream. Thorough knowledge of document structure semantics provides superior information delivery capabilities which far outpace "page-flipper" models.
   Demo Illustration: The DynaText Demos (2) show several interesting and powerful features:
  • - Fast indexing of raw SGML data for online retrieval
  • - Full-text search including boolean, proximity, and document "structure aware"
       searching
  • - Inline and Table of Contents hypertext generation and navigation.
  • - Extensive GUI customization capability
  • A CD-ROM Version of "Who Built America" BIBA 4
      Alexandra Fischer
    In the past, American history has been the exclusive domain of a small and specialized group. Primary documents are often seemingly impossible to access, making it difficult for the non-professional historian to analyze source material and draw their own conclusions. Voyager's CD-ROM version of Who Built America directly confronts this problem by removing the filter of the historian and allowing the user to actually participate in the process of writing history.
       Voyager, with the full cooperation of the authors, has turned one section of the original Who Built America textbook by Steve Brier and Roy Rosenzweig into an Expanded Book. Voyager's version allows the user to not only read the original text (covering the period from 1874-1914), take notes and mark pages (as one would with a traditional book), but it also gives the reader access to the primary documents used by the authors when writing Who Built America. Excursions take the reader to a group of primary documents attached at relevant points in the text, with new texts for each excursion that provides additional context for the documents. The CD-ROM includes 5000 text documents, 600 photographs and illustrations, 75 audio clips (including many archival recordings), and 20 archival film segments (including an entire ten-minute film, The Great Train Robbery).
       The increased indexing capabilities of the CD-ROM version of Who Built America allows the user easy access to the text and attached documents. For example, throughout the text the user can easily find out the number of times a word appears as well as locate all of its occurrences. The excursions can be accessed either through a reference in the text or directly through a primary document index. Town names are annotated with an interactive map attached which allows the user to visualize the patterns of American settlement. And there is a timeline organized according by year and category (e.g. politics, arts, economics, etc.) which provides the user with a more general perspective of American history.
       Who Built America is important because it provides a non-traditional approach to American history, both in the original text and the CD-ROM format in which Voyager presents it. This is the first time that primary documents have been fully integrated with a historical analysis.
    Chimera: Hypertext for Heterogeneous Software Development Environments BIBAK 4
      Ken Anderson; Jim Whitehead
    A major characteristic of modern software development environments (SDEs) is heterogeneity. SDEs are composed of diverse object stores, user interfaces, and tools. The benefits of hypertext in organizing and browsing the immense amount of information stored in SDEs appear obvious. Yet these benefits cannot be realized by hypertext systems that attempt to "control" the environment they are placed in. This control manifests itself in various restrictions, such as requiring all data (both application and hypertext) to be stored in the same database, or requiring a single user interface for hypertext services across all tools.
       Chimera is a hypertext system which attempts to provide hypertext functionality for heterogeneous SDEs in a minimally intrusive fashion. In Chimera, anchors are associated with views of objects, rather than directly with the objects. This has the potential of allowing a complete separation of hypertext information from application data, as well as having anchors be view-specific (consider, e.g., anchors on a Petri-net, which has both a textual and graphical representation).
       Chimera hypertext anchors and links can be created on views of objects displayed by viewers in separate processes. Links can be established on two or more anchors on the same or different views. Since our hypertext information leverages off the concept of a view, links between objects stored in different databases are easily supported.
       The context of this demonstration is the support of a software maintenance process for a flight simulator. The Chimera demonstration illustrates the traversal of links between anchors in graphical views (the flight simulator's instrument panel), word processing documents (as supported by FrameMaker), and requirements documents (as supported by a graph-based tool), all implemented as separate viewers. The demonstration also illustrates the creation of anchors in each of the available viewers, and the creation of links between these anchors.

    PassageWays: SGML Production & Document Management BIBAK 5
      Robert J. Glushko; Bryan Caporlette; Daniel Chang
    PassageWays is an SGML-based document management and production system that supports the automated conversion of information into SGML and the subsequent assembly of SGML into hardcopy and online documents. It provides object-oriented configuration and version management, automated SGML conversion and build environments, graphics conversion, verification and validation utilities, workflow and workgroup management, graphical and command line user interfaces, and integration with other software applications.
       PassageWays abstracts the complexity of SGML, file systems, format conversion tools, and other technology to simplify the creation, management, and production of structured information, while its X/Motif GUI gives information producers an automated user-friendly desktop.
       PassageWays is completely open, and does not assume any single set of development or delivery tools. It can be used to produce online books in a variety of formats, such as Silicon Graphics' IRIS InSight, Electronic Book Technologies' DynaText, and Bellcore's SuperBook. It can incorporate conversion software from Avalanche Technology, Data Conversion Laboratory, or other source. Native SGML authoring using ArborText and conversion to SGML from FrameMaker can peacefully co-exist. The conversion of non-SGML formats to SGML is aided by a "Document Debugger", which invokes the appropriate non-SGML word processor at the position in the source file that causes an conversion error.

    An Environment for Hypertext Application Engineering (ENHANCE) Based on Experiences Gained in ESPRIT Project HYTEA BIBAK 5
      Klaus Meusel
    Technical approach: The demonstration shows a hypertext generator plus targeting tool for electronic catalogs and point-of-sales / point-of-information systems. Markups are added to existing linear material, so that text and graphics can be compiled into a system-independent intermediate format. Standard systems like FrameMaker or ToolBook then can be used for automatic targeting. During the demonstration, we use the target system ToolBook, together with MS Word for adding the markups. The compiler is written in C++. ToolBook is hooked to the open ENHANCE environment by a few scripts implemented in OpenScript.
       Our benchmarks: Within one or two days, authors can design and implement high-quality hyperdocuments of about 500 ToolBook pages. The compilation and automatic targeting process for 500 pages with text, graphics and links takes about 5 minutes.
       The theoretical background: The approach is based on HDM and the ESPRIT project HYTEA. The idea is to keep hyperdocuments consistent and to reduce authoring costs by authoring on an abstract, global level (authoring-in-the-large). By focusing on a special class of applications, the general concepts of HYTEA were transformed into our industrial environment. After instance specification for a predefined schema, the following HDM objects are created automatically:
  • - entities
  • - applicative links
  • - structural links To improve the quality of the applications, an extra effort was put into the professional design of the user interfaces. The demonstration will show the authoring process, compilation and final hyperdocuments. Issues on hypertext interface design (corporate identity, screen layout, use of a grid, typography, etc.) can be discussed by navigating through the running applications.

  • The Microcosm Link Service: An Integrating Technology BIBAK 6
      Wendy Hall; Hugh Davis
    Microcosm has been used extensively over the last two years to develop a number of applications that demonstrate its capabilities as an open hypermedia system and its ability to provide a link service across different types of application packages. This demonstration will show some of these applications, chosen to illustrate the capabilities of the system. In particular we will be demonstrating the use of Microcosm with the 3D-modelling package Autocad, to show how the link service can be applied to packages of this nature and also how a 3D-model can be used as an interface to a set of hypermedia documents.

    DHM -- A Dexter-Based Hypermedia System BIBAK 6
      Kaj Grønbæk; Jens A. Hem; Lennert Sloth
    DHM is a cooperative hypermedia system supporting users' navigation in and editing of shared materials. Cooperation support includes long term transactions, flexible locking and awareness notifications based on OODB technology. The hypermedia functionality fulfils the Dexter Hypertext Reference Model, including: Multi-headed (n-arity) links with bi- and uni-directional traversal. A variety of composites being used for TableTops, browsers and collecting results from simple queries. DHM exists in several variants, including a combined Unix(Sun)/Mac configuration supporting cross platform sharing of hypertexts. DHM is based on a platform independent object oriented framework for building Dexter model compliant hypermedia systems. DHM is also an open hypermedia system allowing integration of third party applications.

    The Artifact-Based Collaboration (ABC) System BIBAK 7
      Kevin Jeffay; John B. Smith
    ABC is a multi-user hypermedia system intended for distributed collaborative groups. Novel features include the following:
  • a data model based on graph theory, conservatively extended to meet
       hypermedia requirements,
  • a scalable data store that is implemented in a distributed architecture
       allowing data to be stored in multiple locations and moved among locations,
  • an open architecture that permits users to incorporate existing applications
       into an ABC environment,
  • a general layer of infrastructure that permits any application to be
       conferenced (shared) over the network. We will demonstrate several users working on the same hypermedia structure both independently and collaboratively.

  • Navigational Search in the World-Wide Web BIBAK 7
      Reinier Post
    The X-Mosaic World-Wide Web browser, developed at NCSA, is quickly becoming the most popular interface for WWW hypertext documents, Gopher and WAIS databases and other sources of information, available on the Internet.
       X-Mosaic offers a point-and-click interface for hypertext documents and a keyword search interface for Gopher and WAIS databases. Keyword searching is not possible in WWW documents, while following hypertext links is not possible in the searchable (index) nodes of the databases.
       We augmented X-Mosaic with a navigational query algorithm for hypertext, providing keyword search at the client side. This is seamlessly integrated with the server-based keyword search for Gopher and WAIS databases. The new interface makes X-Mosaic a much more effective tool for finding information in the Internet.
       Regular expression search and the search for multiple keywords are currently available. Searching is time consuming and can therefore be limited by means of several parameters. Future plans include client-caching to reduce the network load caused by the retrieval of documents over the Internet.

    Using World-Wide Web Hypertext as a Generic User Interface BIBAK 8
      Steve Putz
    I have been experimenting with World-Wide Web (WWW) at Xerox PARC to provide a generic user interface to a variety of information sources and services. One example is a World Map Viewer which utilizes the ability of WWW hypertext documents to include images along with formatted text and hypertext links.
       For the Map Viewer application, links embedded in an HTML document are used as controls allowing the user to change map rendering options (e.g. pan, zoom, level of detail). Additional user input can be obtained via the search keyword capability provided by WWW browsers. The HTML format and the HTTP protocol are in effect used as a generic user interface tool kit to provide not only document retrieval but a complete custom user interface.
       Links in each Map Viewer document (with labels such as "Zoom In") have URLs corresponding to different map rendering parameters, allowing the user to modify the map image by selecting the links. The view can also be modified by selecting on the map image itself.
       Users may interact with the Map Viewer using any WWW browser that supports in-line images in HTML documents, such as the NCSA Mosaic client developed at the University of Illinois at Urbana-Champaign.
       The significance of this application lies in the ease with which the server was created and the ease with which it is made accessible as a network service to users throughout the world. In the first four months it has been available on the Internet, the Map Viewer server at Xerox PARC has received over 100,000 requests from 5,600 users from around the world.

    HyperWriter 4.0: A Hypermedia Architecture for Diverse Applications BIBAK 8
      J. Scott Johnson; Brian C. Giedt
    NTERGAID will be demonstrating the HyperWriter family of hypermedia authoring tools including HyperWriter 4.0, HyperWriter for Training and the HyperWriter AutoLinker. Three key aspects of HyperWriter 4.0 that will be demonstrated are the HW-Basic internal scripting language, the HyperWriter 4.0 text retrieval engine, and a new system for formatting and graphically presenting both rich text and tables. The HyperWriter 4.0 text retrieval engine integrates full text retrieval capabilities with HyperWriter's native hypertext linking as well as extending the text retrieval facilities into the hypertext arena. Additionally, several real world applications of HyperWriter will be demonstrated including online documentation, interactive training and using HyperWriter as a hypertext help system. Also demonstrated will be an early version of HyperWriter for SGML -- a SGML to hypertext delivery environment using the Omnimark SGML parsing engine. The demonstrations will be conducted by J. Scott Johnson and Brian C. Giedt, the designers of the HyperWriter system.

    The Philadelphia Project: A Hypermedia Application in Theatre History BIBAK 9
      John R. Wolcott
    The Philadelphia Project is a hypermedia application which manages complex textual and visual data relating to the development of the city of Philadelphia and the growth of the professional theatre in the United States between 1794 and 1835. What distinguishes The Philadelphia Project is its design to accommodate various learning styles and needs: it addresses both student users whose goal is to learn generally about the Philadelphia theatre and its role in the city's cultural life, and experienced scholar-researchers who wish to examine directly the primary textual and iconographic data. The centerpiece of the database is a to-scale 3D computer model of America's first professional theatre, the Chestnut Street, which serves as a gateway to associated textual and pictorial information in the database.
       In conjunction with the Henry Art Gallery at the University of Washington, a laser disk has been prepared with hundreds of examples of historic clothing and accessories. The disk also contains performances in the style of the early Federal period, and examples of actors performing in 19th century settings, created through the use of video chroma-key and a large theatre model from the period.

    A CAI System for Linear Algebra Based on "World Wide Web", Xmosaic and a Few Special Purpose Programs BIBAK 9
      S. Arnesen; H. Bjar; T. Gulliksen
    Undergraduate mathematics education is one of the factors limiting the number of students our university can accept. Demand for higher education, is both large and increasing, and only limited resources are available for building new universities. Several alternative paths are being investigated in order to increase the productivity of the existing universities. One of these paths is Computer Aided Instruction.
       Our objective was to see if it was possible to create a CAI-system that actually helps students while using open standards and free software making it possible to give a large number of students access to the system at a relatively low cost.
       The tools we chose to use was the SGML based HTML markup language for hypertext documents, the Xmosaic browser for HTML-based World Wide Web documents developed by the NCSA at the University of Illinois at Urbana-Champaign.
       We extended HTML to allow us to include formulas from TeX and plots and animations from Mathematica. Perhaps more interesting is the special markup introduced for pedagogical elements such as explanation of concepts, revealing of hints, and gradual revealing a document.
       The initial courseware is structured as reviews of previous exams. Since reviews of previous exams is a widely used pedagogical method, it lessens the number of new concepts the teachers has to learn. A teacher can directly use her pedagogical skills instead of first having to develop into a interface designer.
       A relatively simple extension to the HTML language can be used as a pedagogic markup language, encoding concepts such as hints and stepwise disclosure of a solution. The courseware produced using this tool is in a format easily accessed by the World Wide Web protocol, thus making it simultaneously available to a large number of users in an heterogeneous internet environment.

    World-Wide-Web Hypertext in Physics Research BIBAK 10
      Vladimir Chaloupka
    Two large physics Collaborations are experimenting with hypertext webs built with the World-Wide-Web (WWW) technology. The projects are the Study of Charm Baryons (Experiment E781) at Fermilab, and the Deep Underwater Muon and Neutrino Detection (DUMAND) off the coast of Hawaii. The webs are publicly accessible from WWW. The best way to access the WEB is with a graphic browser such as Mosaic. The most rudimentary, but universally available, method of test -- browsing is
  • "telnet info.cern.ch"
  • "go http://web.phys.washington.edu/" (once on the WEB, it should be easy to quickly find out how to get Mosaic or other advanced browsers)
       The goal is to build webs capable of providing a prompt answer to (almost) any question about the experiments, serving a broad range of users (from the members of the two Collaborations needing a particular technical detail, all the way to the outsiders interested in a popular introduction). Both projects are at a stage where the real usefulness of this approach can be evaluated.

  • A Semantic Database Approach to Hypermedia Systems for the Museum of Local History BIBAK 10
      Carl Taylor; Douglas Tudhope; Paul Beynon-Davies
    The demonstration will show how a semantic database approach can be used to create hypermedia systems within the domain of local history museums. The demonstration will present an architecture based on an idea originally developed for database work -- the binary relational store. The store's power derives from its use of a single, uniform data structure. This structure can be used store both intensional and extensional information and is capable of representing abstraction in the application design. Through the presentation of two prototypes, Great Inclinations and HyperSHIC, it will be shown how the architecture might support automatic maintenance, different interface / navigation units such as general public browsing, more focusses activity, and authoring or classification by the curator.

    Balancing Ranking and Sequential Ordering in the Presentation of Search Results using Discussions BIBAK 11
      Alan J. Wecker
    Ranked lists of search results for in-book searches can lose sequence information which is valuable both to the user and to the retrieval/browsing system. We have conceived a unit of organization called the "discussion" to overcome this problem. A discussion is simply a contiguous region in a document which addresses a certain topic. Search results are presented as a ranked list of discussions, where the discussions are created dynamically based on the raw search results. Our demo, using a modified version of IBM BookManager READ/2, shows an implementation of discussion ordering, with parameters to interactively control discussion size and density. This technique is also relevant to hypertexts, information filtering, and other applications which combine the notions of sequence and relevance.

    CSILE: A Collaborative Educational Hypermedia System BIBAK 11
      Peter Rowley; Jim Hewitt
    The goal of the Computer-Supported Intentional Learning Environments (CSILE) Project at OISE is to build (a) an instructional theory driven by cognitive science research into collaborative learning processes and expert knowledge organization and (b) a collaborative educational hypermedia system to support educational practice inspired by the theory.
       We seek a new instructional theory to address the problems of inert knowledge and to encourage development of cognitive skills and attitudes associated with sustained inquiry. If students are merely exposed to curriculum content in a task-oriented context of doing projects, writing essays, taking tests and the like, there is a high likelihood of them remembering what they have been exposed to only as disconnected "inert" facts, if they remember them at all. In contrast, if students are actively engaged in establishing learning goals, stating their preconceptions about a phenomenon, seeking new information to fill in gaps, and reformulating their theories in conjunction with (and as a result of being challenged by) others, they tend to remember what they have learned more deeply and are better able to apply it in novel situations. They also begin to develop a genuine appreciation of the culture of sustained collaborative inquiry.
       The CSILE System's design is based on classroom experience and on the foundational theory, and in turn provides support for classroom experiments to test its predictions. It has been iteratively developed over the last seven years and is now in use in approximately a dozen schools across North America.
       We are demonstrating the latest version of CSILE, running on a small network of Macintosh computers, and will be showing CSILE's facilities for asynchronous integrated expression, discussion of, and reflection on knowledge in textual and graphical form. Our current research includes providing overviews of important links and other relationships within the database.

    INTELTEXT: Producing Coherent Textual Sequences While Navigating in Large Non-Hierarchical Hypertexts BIBAK 12
      Dmitry Subbotin
    IntelText is a software tool intended for accessing and arranging loosely structured information. The approach is based on a set of heuristic rules of navigation in a hypertext network.
       IntelText is capable of drawing out text items from a heap of information and representing them in a well-ordered sequence. Text items can be thoughts, facts, messages, abstracts etc. The user links the items (manually or automatically), forming a hypertext network. A link has no direction, weight, or other attributes. Its presence indicates just the semantic closeness of a pair of items. This implies the preference for mono-semantic text items.
       The automatic (algorithmic) navigation becomes possible in the network, based on the correspondence between topological and semantical connectedness of items. The algorithms provide for composing of well-ordered sequences of text items. The user sets the theme which he/she is interested in, by indicating the initial item. On each step of navigation the next item is chosen that is semantically (and topologically) close to the previous part of the navigation route, i.e. its links with already included items are considered.
       Depending on the kind of information, the resulting text sequence (the navigation route) can be either an ordered selection of information elaborating the given theme, or even a linear text. The application area of IntelText can be compilation of surveys, analysis of a flow of messages or a set of ideas, intelligent selection and arranging of information, authoring work, etc.

    Microsoft Access Cue Cards BIBAK 12
      Cyndi Bieniek
    Cue Cards are like an online coach. They allow people to do their own work as they learn Microsoft Access. Cue Cards provide step-by-step guidance through the most common Microsoft Access tasks. They communicate with Microsoft Access to determine what information to display, and can provide prerequisite information based on this communication. For example, if a user wants to create a form but doesn't have a database open, Cue Cards will provide the information on how to open a database first. For new Microsoft Access users, Cue Cards offer a structured yet personalized learning path.
       For Microsoft Access, Cue Cards replace the traditional tutorial, which provides instruction using "canned" examples, and follows a structured, linear path. Cue Cards are revolutionary because they break away from the rigid structure of a tutorial and allow the user follow a decision tree to create his or her own instructional path. Unlike a traditional tutorial, Cue Cards communicate with Microsoft Access and can "customize" instruction based on this communication. Finally, Cue Cards allow the user to work with his or her own data, rather than requiring practice with sample data.

    Developing Global HyperMedia: The NCSA Mosaic System BIBAK 13
      Chris Wilson; Jon Mittelhauser
    NCSA is currently developing a new software tool, NCSA Mosaic, that will encompass all of the currently used global information systems and provide greatly increased functionality and ease of access to the Internet-based universal information space. NCSA Mosaic is a distributed hypermedia information system based on the World Wide Web technology originated by CERN. Mosaic provides a unified, coherent, hypermedia-based portal to the expanding Internet information space by enabling transparent access to all of the major information systems currently in use on the network (Gopher, WAIS, anonymous FTP, Archie, Usenet news, etc.). By virtue of its World Wide Web basis, Mosaic also provides a unique, flexible and important networked information functionality not available in other existing systems -- distributed hypermedia. In addition, Mosaic provides user- and community-level annotation and hyperlink support for collaborative work based on information accessible on the network. Mosaic is being developed across the X Window System, Macintosh and Microsoft Windows environments. Mosaic was originally conceived as an asynchronous collaboration system -- an environment for geographically distributed group or community members to operate on a common networked information base as part of their everyday work Current and future development will focus on enabling and expanding capabilities for information sharing, collaborative navigation and local information space construction across the global information space. Mosaic already supports extensive local information space customization methods, including text and audio annotations that can be attached transparently to any document available from any information source on the Internet. Future efforts will evolve this into a general system for sharing annotation, hyperlink, and document and information space construction activities across small and large groups and communities alike. As a result of these efforts, Mosaic and the Internet will become a flexible, malleable, and extensible information and collaboration system for a wide variety of uses by a large number of people, both independently and in groups and organizations.

    SuperCat in the SuperBook Document Browser System BIBAK 13
      Carol Lochbaum
    SuperCat is an automatically generated catalog of electronic documents that allows users to locate and access documents from a very large collection. SuperCat is simply added as another "document" to an existing SuperBook library, requiring no modification to the SuperBook browser itself.
       Finding a desired document in a full text database is a challenging problem. Typically catalog entries contain very limited information such as the title, author, and a few keywords, making it difficult to identify relevant documents. Moreover, different users may prefer different arrangements or views of a collection of documents, for example, chronologically vs. by author.
       SuperCat addresses these problems by providing one or more document catalogs for the SuperBook interface, taking advantage of the SuperBook search and navigation tools available for individual documents. Since SuperCat is automatically generated, the problem of frequent updates to the library can be dealt with efficiently.
       For alternative views of a document collection, several differently organized SuperCats can be constructed, without having to replicate the documents themselves.
       A SuperCat catalog contains the abstract or first 100 lines or so of text, the section headings, and hypertext links to the full text and graphics of each SuperBook document. Users first access SuperCat, then go to the actual documents using the links. Because SuperCat contains the complete heading structure of each document, which is fully indexed, it represents an improvement over traditional catalogs which generally contain only titles, keywords, etc.
       The demonstration will show how SuperCat is used to find documents in the SuperBook browser, and will also show how a new SuperCat is created when the SuperBook library is updated.

    Browz-All: A Hierarchical Hypertext System BIBAK 14
      Joel Remde
    Browz-All is a prototype hypertext user interface based on a hierarchical organization of information objects. Browz-All addresses the problem of efficient access -- any needed information should be available to the user, but frequently used items should require the least effort to access.
       A hierarchical design was chosen for several reasons: it has been successful in the SuperBook system; it scales up naturally; it allows flexibility in the amount of detail shown; and hierarchies are structures familiar to people.
       The user's own "information world", including both public and private information, is depicted in Browz-All as a hierarchy or tree of text icons. Detailed objects appear separately as tiled windows, and the user can easily switch between the two views.
       The tree can be expanded at points of interest until the desired information objects are found. The upper portion of the tree, which is always visible, provides context for the information to avoid the problem of "getting lost". Exploration and manipulation of the tree is done via a mouse gesture command interface. The tree structure can be customized according to the user's own needs or conceptual organization. Items may be placed under as many categories in the hierarchy as desired; color cues help identify them for navigation purposes.
       The system, not the user, manages screen layout, relieving the user of positioning and uncovering windows. This is supposed to improve efficiency of use. Browz-All attempts to keep frequently or recently used items visible and pushes such items toward the top of the tree where they can be found more readily.
       The demonstration will include a sample hierarchical "information space", and will show how it can be customized, navigated, and how new information can be incorporated.

    eText: An Interactive Hypermedia Publishing Environment BIBAK 14

    The eText engine lays the foundation for a document-centric interface to a multimedia information space, affording an ease of construction and navigation heretofore absent in large-scale hypertext publishing systems. eText realizes its power from the innovative notion of a "self-aware" document, leveraging a portable file format (RTF) manipulated by an object-oriented graphical user interface under NeXTSTEP. The eText architecture abstracts and encapsulates conventional semantics for authoring systems into three classes of annotations to an underlying rich-text document: multimedia, interactive media, and hypermedia. The eText system has been developed for the Archetypes project, which aims to produce an online, extensible reference -- and text-book for teaching parallel programming. To that end, eText is designed to easily incorporate and cross-reference new documents, to support interactive educational material, and to adapt to individual student preferences. Soon, eText will also support the creation of an integrated development environment for writing parallel and distributed programs within the Archetype paradigm. This is possible because eText also supports an innovative ability to attach domain-specific Editors to individual documents, live objects which assist the user in the creation and editing of the document as a whole. For example, a source-code document can not only support hypermedia annotations to the code, but can also be attached to a code Editor, which offers syntax checking, version control, and debugging. Such Editors are the first step towards active agents in the construction of hypertexts. This demo is a work-in-progress, so interested parties are encouraged to contact the presenters directly. Public release of eText is projected for Q1 '94, tied to public release of the first chapters of the Archetypes Electronic Textbook. During 1994, we look forward to forming a consortium of parties interested in Archetypes and eText, as well as the development of document cross-compilation technology to allow viewing of eText documents on Macintosh and Windows platforms.

    Health Sciences Hypertexts at Columbia-Presbyterian Medical Center BIBAK 15
      Jeff Zucker; Robert M. Kahn; Narayanan Natarajan
    At the Columbia-Presbyterian Medical Center (CPMC) we have developed a number of hypertext and free text retrieval computer applications aimed at an extremely diverse audience which includes students and faculty in a university setting as well as health care providers and patients in hospital and clinic settings. Each application must be accessible to people from a variety of computer skill levels, from a variety of medical skill levels and from a variety of disciplines. In addition to the diversity of users, the CPMC applications encompass a diversity of text sources. Some sources such as the Physicians Desk Reference and the Guide to Clinical Preventive Services come from established print sources. Others such as the Medical Logic Modules Library and the Nursing Standards & Patient Education System were designed at CPMC specifically for use on computers. A third category of sources is represented by the Funding Opportunities database that we have adapted from an unwieldy relational database into a more flexible free-text retrieval system. Hypertext and free text systems offer features which make them ideal for presenting information from both computer and text sources in a manner that is individualized to the needs of users in a wide variety of learning contexts. We built traditional linear indexes which are familiar to those accustomed to the print sources. At the same time, we encourage a more freeform approach for those who wish to access the information in a more flexible manner. Ad hoc text searches and hard coded links allow users to combine information in ways not possible in the print equivalents of the applications. Hypertext links also allow for a more inclusive approach to user help and user feedback -- many of our applications allow several levels of help and have hot links which allow users to communicate directly with the developers and managers of the information.

    ArborText's Hypertext Utilities for Authoring, Accessing, and Managing Information BIBAK 16
      Paul Klock
    The ArborText product demonstration gives ACM Hypertext '93 attendees hands-on experience with the ADEPT Series, a set of electronic publishing tools which support the creation and use of hypermedia documents.
       Underlying the ADEPT Series is a powerful programming language called the ADEPT Command Language. The Command Language gives hypermedia document developers the open system tools they need to implement hypertext applications. The Command Language is oriented to SGML information structures and it provides control of the rules, conditions, and actions of the hypermedia authoring system.
       For more tightly coupled hypermedia authoring applications, ArborText also provides an Application Programming Interface (API). The API allows an author to establish two-way communication between any document editing session and one or more other programs, e.g., a database system or full motion video application. All the programs are aware of events in the other programs and are able to exchange information freely through the API.
       ArborText uses Standard Generalized Markup Language (SGML) as its document structure. SGML is an International Standards Organization standard (ISO 8879) developed to facilitate document definition and interchange.
       SGML is a language for expressing documents in terms of their content and organization. In essence, the Document Type Definition (DTD) is the rule for defining and organizing Information Objects within a document. It provides the data structure against which the hypermedia document operates. The Information Objects can have as little or as much granularity as desired.

    Hardhat HyperText -- Interfaces that Work in Industrial Workplaces BIBAK 16
      Bruce A. Warren; Neil Blahut
    Popular hypertext user interfaces are designed by office workers, which is probably why they get rejected by operators in chemical plants. Missing are simplicity, robustness, scalability, customizability, speed, network document sharing, and navigators that make millions of pages quickly accessible with just a few mouse clicks. We will be demonstrating a user interface developed by trial and error during six years of in-plant use. The interface works in high pressure production environments to deliver documents and interactive training with no training required to use the terminal. The interface allows quick navigation through millions of documents using job-specific navigators. Documents are accessed by clicking on text, drawings, diagrams, and pictures. Industrial applications for hypertext and multimedia are here now -- electronic job aids, interactive training, document management. This massive market is being held back by consumer oriented hypertext interfaces being mis-applied to unforgiving industrial applications.

    Lust: A Hypertext Fiction BIBAK 17
      Mary-Kim Arnold
    "Lust" is a hypertext fiction of 36 nodes. It was developed in Robert Coover's experimental narrative workshop, and it addresses some of the issues specific to writing fiction in an electronic environment. These issues include repetition, multilinearity, multivocality, indeterminacy, narrative structure, and user interaction.
       The piece itself is an exploration of language and form. It begins with a prologue consisting of exactly thirty six words, and each word links to a particular node. Each node is linked to several others; some are text links, some are guarded space to space links. Because each reading is reader determined, each reading is unique, and the meaning and content of the story is changeable and transient. This feature of the piece calls attention to the indeterminate nature of language itself, and of hypertext fiction. Because there is no specific linear beginning, middle and end, the narrative is ongoing and changeable.
       Because each node uses one of an limitless number of points of view from which the "action" can be seen, the story is told and retold, with no one interpretation being superior to any other. It requires the reader to put the disparate pieces of information together, while also drawing the reader into the process of writing the story, since the reader chooses which words have texture to her, which determines the order in which the information is disclosed.
       In many ways, a piece like "Lust" embodies the nature of hypertext itself, in terms of fictional hypertext, at least. The structure of the piece (in this case, small, tight, limited) becomes part of the content, and perhaps in some cases, more important than the specific language used.

    DNE: An Internet Protocol for Hypertext Interoperability BIBAK 17
      Don McCracken; Robert Akscyn
    Present schemes for cross-application node/data linking tend to be operating system specific (e.g., OLE for DOS). They also tend to focus on linking services -- node and script services are sometimes not provided for. An alternative approach is to use an internetworking protocol that allows hypertext systems (and other systems wishing to provide node and link services) to interoperate (like WWW). This demonstration will illustrate a prototype internetworking protocol developed to explore interoperability of hypertext system and possibly provide an architectural foundation for large-scale hypermedia-oriented digital libraries.
       This protocol, called "DNE" for "Dynamic Node Exchange", provides a means to experiment with cross-system node, link, and script services. Protocols such as DNE, if based on a sufficiently broad data model, could provide a simple way for hypertext systems to interoperate, possibly allowing very large hypertexts to be constructed by integrating multiple heterogeneous hypertext databases. The demonstration will illustrate the work accomplished to date by using an existing hypermedia system (KMS) and accessing nodes from a number of remote sites over the Internet. The demonstration will also contrast the approach with other internet-based schemes such as World-Wide Web and Gopher.

    A Demonstration of MetaCard: "The World's Largest HyperCard Application" BIBAK 18
      David D. Sherertz
    MetaCard is a hypertext Metathesaurus browser implemented using HyperCard. The Metathesaurus is one of three Knowledge Sources released annually, since 1990, as part of the National Library of Medicine (NLM) Unified Medical Language (UMLS) Project. The current version of MetaCard contains over 400 MBs of information in 146 stacks and index files, about more than 152,000 biomedical concepts, including names, definitions, semantic types, and relationships. MetaCard supports both the display of biomedical information and navigation using the semantic relationships present. The principal metaphor is "click to get more information." Several hundred sites worldwide run MetaCard off the NLM-distributed CD-ROM.
       Virtually everything the user sees in the interface is "live", in the sense that almost anything can be clicked on, and it will do something. There are close to 10 million inter-card links amongst over 182,000 cards organized into 137 HyperCard stacks. The demonstration will also illustrate the notion of a "no-typing" interface by using only "pointing and clicking" to navigate to biomedical concepts of interest to members of the audience. Audience involvement as participants in "Stump the Metathesaurus" will also illustrate the breadth of coverage in the current release of MetaCard. In spite of its shortcomings, MetaCard remains a remarkable artifact. We know of no other low-end, point-and-click implementation of comparable scale. After some explorations with a few contacts at Apple we began claiming that MetaCard was the world's largest HyperCard application and then waited for someone to contradict us. We are still waiting.

    Hypertext on the Corporate Help Desk BIBAK 18
      Tom Rearick
    This presentation will demonstrate hypertext embedded in a corporate help desk application. The challenge is to empower the help desk professional by leveraging the collective resources in the corporation itself. The integration of Lotus Notes and Lotus SmarText provide a complete solution to in-house electronic publishing and collaborative problem-solving. Lotus SmarText automates the conversion of existing text files into hypertext-rich electronic books. Lotus Notes combines communication and database technologies to increase business productivity. A real-world help desk application will demonstrate how customer support professionals use Lotus Notes to:
  • Resolve customer problems
  • Verify product deficiencies and report them as part of a continuous program
       of product improvement
  • Simplify resource planning and management
  • Collect useful information and disseminate it to other help desk personnel.
  • Provide feedback to the documentation department Complementing Notes, Lotus SmarText is used to:
  • Add value to existing corporate documentation
  • Search a large corpus of text quickly and reliably
  • Deliver value-added product support information to user's sites. This demonstration will illustrate how these two products work in concert, not in a single department but across the entire Company and among its customers. Lotus SmarText and Notes are not simply alternatives to paper documentation, but a means for effecting positive change in the corporation.
