Abstract

Describes the backgroud to the construction of a thesaurus at Hydro-Quebec, Quebec, Canada. Several information units, linked to form a network, share the same bibliographic database. The need for coherence and efficiency was the principle motive for the construction of the multidisciplinary thesaurus. Describes the construction process, discusses the specifity of the tool, its circulation, and considers its use on a partnership basis with other information services

Abstract

Z39.50 is an information retrieval protocol. It has generated much interest but is so far little deployed in UK systems and services. Gives a functional overview of the protocol itself and the standards background, describes some European initiatives which make use of it, and outlines various issues to do with its future use and acceptance. Z39.50 is a crucial building block of future distributed information systems but it needs to be considered alongside other protocols and services to provide useful applications

Abstract

Proposes a new model for bibliographic access, the virtual catalogue, to serve the virtual library. Suggests the use of current software and networks to build links between bibliographic databases of all kinds, including full text, to enable the user to search a specified subset of databases. Suggests that local data be limited to holdings information linked to, but separate from, bibliographic databases both local and remote

Abstract

Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

Abstract

The aims of CATRIONA were: (1) to investigate the requirements for developing procedures and applications for cataloguing and retrieval of networked resources, and (2) to explore the feasibility of a collaborative project to develop such applications and procedures and integrate them with existing library systems. The project established that a distributed catalogue of networked resources integrated with standard Z39.50 library system OPAC interfaces with information on hard-copy resources is already a practical proposition at a basic level. At least one Z39.50 OPAC client can search remote Z39.50 OPACs, retrieve USMARC records with URLs in 856$u, load a viewer like Netscape, and use it to retrieve and display the remotely held electronic resource on the local workstation. A follow-up project on related issues is being finalised.

Abstract

Federated search and distributed information retrieval systems provide a single user interface for searching multiple full-text search engines. They have been an active area of research for more than a decade, but in spite of their success as a research topic, they are still rare in operational environments. This article discusses a prototype federated search system developed for the U.S. government's FedStats Web portal, and the issues addressed in adapting research solutions to this operational environment. A series of experiments explore how well prior research results, parameter settings, and heuristics apply in the FedStats environment. The article concludes with a set of lessons learned from this technology transfer effort, including observations about search engine quality in the real world.

Abstract

Der vollständige Projektname von Renardus lautet "Academic Subject Gateway Service Europe". Renardus wird von der Europäischen Union im 5. Rahmenprogramm mit dem Schwerpunktthema "Information Society Technologies" im zweiten Thematischen Programm "Benutzerfreundliche Informationsgesellschaft" ('Promoting a User-friendly Information Society') gefördert. Die Projektlaufzeit ist von Januar 2000 bis Juni 2002. Insgesamt zwölf Partner (Principal und Assistant Contractors) aus Finnland, Dänemark, Schweden, Großbritannien, den Niederlanden, Frankreich und Deutschland beteiligen sich an diesem Projekt. Die Europäische Union unterstützt das Projekt mit 1,7 Mio. EURO, die Gesamtkosten belaufen sich inklusive der Eigenbeteiligungen der Partner auf 2,3 Mio. EURO. Das Ziel des Projektes Renardus ist es, über eine Schnittstelle Zugriff auf verteilte Sammlungen von "High Quality" Internet Ressourcen in Europa zu ermöglichen. Diese Schnittstelle wird über den Renardus Broker realisiert, der das "Cross-Searchen" und "Cross-Browsen" über verteilte "Quality-Controlled Subject Gateways" ermöglicht. Ein weiteres Ziel von Renardus ist es, Möglichkeiten von "metadata sharing" zu evaluieren und in kleinen Experimenten zwischen z. B. Subject Gateways und Nationalbibliothek zu testen bzw. zu realisieren

Abstract

The success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.

Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
The papers discussing the transformation of traditional tools locate the point of transformation in different places. Some, like the papers an DDC, LCC and UDC, suggest that these schemes can be imported into the networked environment and used as a basis for improving access to networked resources, just as they improve access to physical resources. While many of these papers are intriguing, I suspect that convincing those outside the profession will be difficult. In particular, Edward O'Neill and his colleagues, while offering a fascinating suggestion for preserving the Library of Congress Subject Headings and their associated infrastructure by converting them into a faceted scheme, will have an uphill battle convincing the unconverted that LCSH has a place in the online networked environment. Two papers deserve mention for taking a different approach: both Francis Devadason and Maria Ines Cordeiro suggest that we import concepts and techniques rather than realized schemes. Devadason argues for the creation of a faceted pre-coordinate indexing scheme for Internet resources based an Deep Structure indexing, which originates in Bhattacharyya's Postulate-Based Permuted Subject Indexing and in Ranganathan's chain indexing techniques. Cordeiro takes up the vitally important role of authority control in Web environments, suggesting that the techniques of authority control be expanded to enhance user flexibility. By focusing her argument an the concepts rather than an the existing tools, and by making useful and important distinctions between library and non-library uses of authority control, Cordeiro suggests that librarianship's contribution to networked access has less to do with its tools and infrastructure, and more to do with concepts that need to be boldly reinvented. The excellence of this collection derives in part from the energy, insight and diversity of the papers. Credit also goes to the planning and forethought that went into the conference itself by OCLC, the IFLA Classification and Indexing Section, the IFLA Information Technology Section, and the Program Committee, headed by editor I.C. McIlwaine. This collection avoids many of the problems of conference proceedings, and instead offers the best of such proceedings: detail, diversity, and judicious mixtures of theory and practice. Some of the disadvantages that plague conference proceedings appear here. Busy scholars sometimes interpret the concept of "camera-ready copy" creatively, offering diagrams that could have used some streamlining, and label boxes that cut off the tops or bottoms of letters. The papers are necessarily short, and many of them raise issues that deserve more extensive treatment. The issue of subject access in networked environments is crying out for further synthesis at the conceptual and theoretical level. But no synthesis can afford to ignore the kind of energetic, imaginative and important work that the papers in these proceedings represent."

Abstract

Managing information from over 375 separate parks is a challenge for the US National Parks Service (NPS). Describes the National Resource Bibliography Project initiated by the NPS, which so far includes more than 100.000 records from over 160 different US parks. The goal is to complete all of the units designated for the project by 1998. The result will be a virtual library comprising document collections from over 300 parks, forming a unique and valuable research tool, available to anyone interested

Abstract

The State Library of Iowa, USA, received a Higher Education Act title II grant from the US Dept. of Education in 1994 to create a demonstration project of new library information technologies. Describes 2 interlinked components of the project: Web-based union catalogue development and statewide deployment of the ANSI/NISO Z39.50 standard for database search and retrieval. Z39.50 was chosen because of its ability to searching multiple remote databases in a single session and its common interface across a variety of implementations. Use of a distributed Z39.50 search makes the need for maintaining large union catalogues unnecessary

Abstract

In this position paper we propose a document-centric middleware component called Living Documents to support context-aware information retrieval in distributed communities. A Living Document acts as a micro server for a document which contains computational services, a semi-structured knowledge repository to uniformly store and access context-related information, and finally the document's digital content. Our initial prototype of Living Documents is based an the concept of mobile agents and implemented in Java and XML.

Abstract

Effective retrieval in a distributed environment is an important but difficult problem. Lack of effectiveness appears to have two major causes. First, existing collection selection algorithms do not work well on heterogeneous collections. Second, relevant documents are scattered over many collections and searching a few collections misses many relevant documents. We propose a topic-oriented approach to distributed retrieval. With this approach, we structure the document set of a distributed retrieval environment around a set of topics. Retrieval for a query involves first selecting the right topics for the query and then dispatching the search process to collections that contain such topics. The content of a topic is characterized by a language model. In environments where the labeling of documents by topics is unavailable, document clustering is employed for topic identification. Based on these ideas, three methods are proposed to suit different environments. We show that all three methods improve effectiveness of distributed retrieval

Abstract

A Virtual union catalog is a possible alternative to the centralized database of distributed resources found in many library systems. Such a catalog would not be maintained in a single location but would be created in real time by searching each local campus or affiliate library's catalog through the Z39.50 protocol. This would eliminate the redundancy of record storage as well as the expense of loading and maintaining access to the central catalog. This article describes a test implementation of a virtual union catalog for the University of California system. It describes some of the differences between the virtual catalog and the existing, centralized union catalog (MELVYL). The research described in the paper suggests enhancements that must be made if the virtual union catalog is to become a reasonable service alternative to the MELVYL® catalog.
