Project NameOkapi (Online Keyword Access to Public Information)
Principal InvestigatorsMicheline Hancock-Beaulieu (firstname.lastname@example.org)
Stephen Walker (email@example.com)
Project SummaryThe original "purpose of Okapi was to test the applicability, in the online catalogue context, of findings from research in interactive computer systems, cognitive psychology and information retrieval (IR)." A key aim of the project was to provide support to users during searching.
Among the features incorporated into the Okapi system during the course of its development were natural language query input, 'best match' ranking of search results, word stemming, spelling correction, cross-referencing of synomyms, automatic query expansion, (AQE) and relevance feedback. Recent enhancements include the incorporation of a thesaurus into the search process, interactive query expansion (IQE), and development of a 'user-configurable' interface within a graphical user interface (GUI) environment.
The Okapi project originated at the Polytechnic of Central London, now Westminster University, in 1982 and continued at the City University beginning in July 1989.

Institute of Research and Coordination in Acoustics / Music. Multimedia Library
Principal InvestigatorMichael Fingerhut (email@example.com)
Product SummaryThe Médiathèque is the multimedia library affiliated with the Institut de Recherche et Coordination Acoustique / Musique (IRCAM), a not-for-profit institute devoted to contemporary music established in the 1970s by conductor and composer Pierre Boulez. Among its areas of interest and activity are: research and development on acoustics, digital signal processing, music perception, and computer-aided composition; organization of colloquia, conferences, and short- and long-term educational programs in computer music technologies, music composition, and musicology; and the publication of books, periodicals, and recordings on technological topics.
The Médiathèque primarily serves the IRCAM staff and professional scientists, composers, musicologists, students, as well as the general public. Its collections consist mostly of books, periodicals, and music scores on contemporary music and technologies (e.g., acoustics, digital signal processing, perception, etc.) as well as online collections of audio recordings, documentary films, CD-ROMs, scientific and musical texts and databases.
The online collections are accessible:
- via links in the central public access catalog records
- by conventional, forms-oriented searching of each collection
- from browsing lists
- by full-text search and retrieval (for the online texts)
- by database search (for the databases), and by
- cross-references from other online documents
The Médiathèque provides access to its public access catalog in four major ways:
- conventional, forms-oriented searching ['Detailed Search']
- browsing by a locally-developed Dewey-like decimal classification
- navigation and searching using a floor plan [?]
- navigation and browsing in 3-D VRML virtual reality
Using the floor plan, users can browse a shelf and the associated classification of library materials on these shelves, and subsequently retrieve the catalog record for selected items, and then the item (text, audio, video, CD-ROM file(s)), if available online.[?]
Navigation and browsing in VRML 2.0 requires installation of the Cosmo player plug-in.
In 3-D, users may select from among several starting points from the Viewpoint List from the Cosmo player navigation bar, notably the
- ENTREE DE LA SALLE DE LECTURE
- POSTE DE DEMONSTRATION
- GALERIE, VERS DE CENTRE GEORGE POMPIDOU
- COINS DES OUVRAGES DES SCIENTIFIQUES
to virtually tour the Médiathèque, browse its shelves and collections, browse and search its catalog, display the catalog record for selected items, and then retrieve the actual item (text, audio, video, CD-ROM file(s)), if available online.
Searching, browsing and display of catalog records makes extensive use of frames.

Project NameThe Library of Congress Experimental Search System
Principal InvestigatorDean Wilder (firstname.lastname@example.org)
Product Summary"This is one of the Library of Congress' first experiments at making both its cataloging and digital library resources available over the World Wide Web through a single, user-friendly interface. The interface consists of the previous search query page and brief help files which link directly from significant words on the search query page. By exploiting the powerful synergies of hyperlinking and a relevancy-ranked search engine (INQUERY from Sovereign Hill), it is hoped this catalog will provide a new and more intuitive way of searching the traditional OPAC (Online Public Access Catalog)."
"Besides the cataloging records for over 4 million books; ... 263,000 motion pictures; 200,000 sound recordings and scores; more than 150,000 maps; and 4,300 computer files .., this catalog also contains the cataloging for almost 140,000 photographs and manuscripts in the National Digital Library Program's American Memory, linking to more than 70,000 digital photographs and images available online." "... [L]inks are also provided to the fulltext of over 2,500 online books from sites across the Internet."
"The real strength of this catalog lies in its ability to show the relationships between free text terms, controlled vocabularies (e.g., Library of Congress Subject Headings), and classification schedules. As more and more government and other public domain documents become available in fulltext, these can be linked to cataloging records to provide a single point of entry to the emerging national digital library infrastructure. This will allow users to experience enriched, controlled vocabulary searching with relevancy ranking which will enable them to quickly identify, locate and access materials that have been converted to digital formats at multiple institutions, not only the Library of Congress."
"While this catalog does not replace existing Library of Congress systems, the principle it exhibits of immediate access to fulltext materials and digital objects will hopefully encourage the migration of existing systems, both here and elsewhere, in a similar direction." "The retrieval system used on this database is INQUERY, developed by the Center for Intelligent Information Retrieval at the University of Massachusetts, Amherst."

Product SummarySuperPAC is a vision of "an enhanced online public access catalog with features that allows users to better evaluate the wide range of information sources made accessible through new technologies." Two types of OPAC enhancements are proposed: the integrated availability of electronic evaluation sources, and the use of improved and augmented MARC records.
The primary focus of SuperPAC is the concept of the transparent workstation. As a complete workstation, SuperPAC must encompass not only the individual library's online catalog, but a full range of bibliographic databases and other resources, a variety of electronic journals, and access to bibliographic utilities, among other information sources.
The proposed system recognizes the need for users to critically evaluate identified information and incorporates access to an variety of traditional and novel evaluation sources, notably book review sources, biographical sources, journal evaluation sources, book publisher information, and local reviews.
The SuperPAC model also incorporates augmented MARC record data that includes evaluative information elements and more fully indexed and searchable fields. An enhanced MARC 555 (cumulative index and finding aid) field, augmented MARC 545 (biographical and historical note), an enhanced MARC 505 (contents note) field, and an enhanced authority file are among the recommended additions.

Project NameCheshire II
Principal InvestigatorRay R. Larson firstname.lastname@example.org
Product Summary"The Cheshire II online catalog system was designed to provide a bridge between the realms of purely bibliographical information and the rapidly expanding full-text and multimedia collections online. It is based on a number of national and international standards for data description, communication, and interface technology. The system uses a client-server architecture with X window client communication with an SGML-based probablistic search engine using the Z39.50 information retrieval protocol."
The "design elements of the Cheshire II system represent a significant advance over the simple left-to-right matching of subject headings used in first generation online catalogs, and the Boolean keyword matching used in second generation online catalogs. The Cheshire II system was designed to be a next- or third generation online catalog using advanced information retrieval techniques to improve subject searching performance, help combat the twin problems of search failure and information overload, and to support networked access to global information resources using standardized information retrieval protocols."

Mark P. McCahill (firstname.lastname@example.org)
Project Summary"GODOT (GopherVR Organized Directories Of Titles) is a tool that creates spatial organization of an author's works. Using an ISO Z39.50-1994 client to connect to remote library catalogs, GODOT extracts an author's work in the form of USMARC bibliographic records." It then proceeds to format and classify the MARC records, creating an organization which can be browsed and searched. Users can explore the works of an author using both Gopher and Gopher VR clients. A Gopher client provides linear lists, while GopherVR visualizes the relationship and structure within these lists.

Project NameInformatics Library Floor Plan
Principal InvestigatorKnut Hegna (Knut.Hegna@ub.uio.no)
Project SummaryThis unique interface provides users with the ability to search the OPAC of the Informatics Library at the University of Oslo using a image-map floor plan of the library's collection. As a specialized center in Informatics, the library has adopted the Association of Computing Machinery (ACM) classification system its the organization. Users can browse the classification by clicking on an appropriate section of the annotated floor plan denoting the location of works within a specific section of the scheme.
Once within a specific classification range, the user is presented with a annotated alphanumerical outline of the classification indicating the specific topics included within a section of the scheme. In selecting a particular classification node, those works that have been assigned the classification are retrieved and presented in an item-numbered list, arranged in a LI/FO record order. Selection of the item number will retrieve a brief bibliographic record of the individual title.
The bibliographic record includes hotlinked author, classification number(s) and keyword subject descriptors, allowing the user to expand the search without initiating a new, separate search request.
An outstanding detailed guide for searching the OPAC is also available from the library's homepage.

Project NameVRML to Navigate Information Space
Principal InvestigatorsArt Rhyno (email@example.com)
Project Summary"This project attempts to utilize VRML to navigate through information space and builds on earlier work carried out at the Leddy Library to create VRML scenes "on the fly" using a modified WWW-->Z39.50 gateway. The gateway is based on programs from CNIDR and Stanford University, and includes a function for generating a VRML scene of bookshelves based on a result set, where books on the shelf represent individual items returned from the target database...".
"In order to experiment with using VRML to directly navigate large information collections, the bookshelf metaphor needs to be extended, in this case by using the entire collection of the Leddy Library and offering a prototype VRML gateway to the collection using the Library of Congress classification scheme. The prototype requires special indexing and better network integration of the collection than currently found with our mainframe Notis system and will be implemented with our replacement [Endeavor] Voyager system ...".
"The LC classification scheme is modeled as a set of entrances. Walking or 'flying' through one of the entrances gives a further breakdown of the scheme. Visual cues can be used to help the user get a better sense of where they are going. The entrances are traversed until shelves appear using similar logic to that employed in our gateway. VRML is somewhat limited in its ability to display text on 3D objects and the gd graphics library may be used to generate gifs which can be applied to books as textures. This will give more flexibility for displaying title and author information on each volume as well as give an opportunity to create more realistic looking books. Few libraries can afford to lay out their physical collection without significant space constraints, yet with VRML, the virtual view of the collection can be organized to facilitate access in whatever manner works best and can be created at the time of the query."

Project NamesMARIAN (Multiple Access Retrieval of Information with ANnotations)
Principal InvestigatorsEdward A. Fox (firstname.lastname@example.org)
Robert K. France (email@example.com)
Project DescriptionThe aim of the MARIAN system, in part, is to rectify the mechanical and conceptual problems associated with the use of online public access catalogs. It offers more effective search and retrieval features beyond those of the well-established Boolean approach. The long-term development goal is to create an 'intelligent' system with broad usability and 'smart' functionalities such as morphology-based matching, query expansion, authority files, linking and terminological aids and direct interfaces. In searching, MARIAN attempts to find the closest match to a query using an approximate matching algorithm. Results of a search are presented in order of best match.
MARIAN has been developed using a specially-developed object-oriented DBMS with a client running under NeXTSTEP on a collection of NeXT computers.

Project SummaryProject Envision is a user-centered, multimedia database of the computer science literature, with full-text searching and full content retrieval capabilities.
"Envision features flexible information visualization, displaying search results as a matrix of icons. [E]ach document is represented by an icon in [its] Graphic View, while the Item Summary shows a textual listing of bibliographic information. The Graphic View gives users control over how search results are displayed, by manipulating values assigned to the matrix axes. Users can select the interpretation of icon position along the x- and y-axes, as well as icon color, shape, size,and label. Document attributes that can be shown in the display include relevance, publication year, type, size, author name, and index terms."
"The Envision system consists of specially-developed components: a query server, an object-oriented database management system, a presentation server, and the Envision client. The query server is a vector-space search system (i.e. MARIAN). The object-oriented DBMS deals with many kinds of entities and media types." Bibliographic and full-text sources are encoded in SGML and are converted by the presentation server to HTML for final rendering.

Project NameContinuity: An Extensible Intelligent Integrated Collaborative Catalog & Distributed Institutional Memory Archive
Principal InvestigatorPeter J. Wasilko (firstname.lastname@example.org)
Project Summary"Current library catalogs don't reflect how people really work with information, making them very inefficient tools, particularly for users new to a discipline. They represent monolithic centralized efforts to structure access to the written record that are failing to adequately address the growth of that record or to tightly integrate newer forms of scholarly communication (e.g. the Web)."
"The OPAC of the future should have the following characteristics:
- The catalog needs to provide its users with grounding in fields that are new to them.
- It should offer both visualizations of the collection and of scholarly activity using the collection.
- It should support subjective queries and be able to handle a natural language dialog.
- Over time it should develop personal profiles of its users and tailor its responses to better meet their needs.
- It should help them to get into contact with one another and to update the overall store of knowledge to manage errata and incomplete leads.
- It should be designed to be able to function as a distributed system.
- It should have at its highest levels, an object oriented systems architecture to promote well factored extensibility."
