    Abstract
    There has been a recent explosion of interest in digital music libraries. In particular, interactive melody retrieval is a striking example of a search paradigm that differs radically from the standard full-text search. Many different techniques have been proposed for melody matching, but the area lacks standard databases that allow them to be compared on common grounds--and copyright issues have stymied attempts to develop such a corpus. This paper focuses on methods for evaluating different symbolic music matching strategies, and describes a series of experiments that compare and contrast results obtained using three dominant paradigms. Combining two of these paradigms yields a hybrid approach which is shown to have the best overall combination of efficiency and effectiveness.

    Abstract
    Purpose - The paper aims to argue that digital library retrieval should be based on semantic representations and propose a semantic infrastructure for digital libraries. Design/methodology/approach - The approach taken is formal model based on subject representation for digital libraries. Findings - Search engines and search techniques have fallen short of user expectations as they do not give context based retrieval. Deploying semantic web technologies would lead to efficient and more precise representation of digital library content and hence better retrieval. Though digital libraries often have metadata of information resources which can be accessed through OAI-PMH, much remains to be accomplished in making digital libraries semantic web compliant. This paper presents a semantic infrastructure for digital libraries, that will go a long way in providing them and web based information services with products highly customised to users needs. Research limitations/implications - Here only a model for semantic infrastructure is proposed. This model is proposed after studying current user-centric, top-down models adopted in digital library service architectures. Originality/value - This paper gives a generic model for building semantic infrastructure for digital libraries. Faceted ontologies for digital libraries is just one approach. But the same may be adopted by groups working with different approaches in building ontologies to realise efficient retrieval in digital libraries.

    Abstract
    Purpose - To investigate ways of demonstrating how portal implementations positively alter user information retrieval behaviour. Design/methodology/approach - An opinion piece reflecting on existing evidence about the nature of portal implementations, which extrapolates trends in user behaviour on the basis of these reflections. Findings - Although portal technologies probably do offer a way for libraries to create information tools that can compete with "one-stop shop" Internet search engines, there are likely difficulties in their pattern of usage which will have to be detected by effective quality measurement techniques. Research limitations/implications - An expression of opinion about the possible pitfalls of using portals to optimise users' information retrieval activity. Practical implications - This opinion piece gives some clear and practical guidelines for the evaluation of the success of library portal implementations. Originality/value - This editorial points out that, because the portal can be defined as a deliberate clone of a typical successful Internet search engine and may be presented to the naïve user in the same terms, the danger is that library portals might also clone the same information habits as Internet search engines, because of their ease of use. In trying to produce a tool that can meet Google on its own terms but with better content, we might reproduce some of the same educational disbenefits as Google: quality information retrieval is not purely a function of content, it is also a function of the user's perceptions and information habits.

    Abstract
    We are rapidly constructing an extensive network infrastructure for moving information across national boundaries, but much remains to be done before linguistic barriers can be surmounted as effectively as geographic ones. Users seeking information from a digital library could benefit from the ability to query large collections once using a single language, even when more than one language is present in the collection. If the information they locate is not available in a language that they can read, some form of translation will be needed. At present, multilingual thesauri such as EUROVOC help to address this challenge by facilitating controlled vocabulary search using terms from several languages, and services such as INSPEC produce English abstracts for documents in other languages. On the other hand, support for free text searching across languages is not yet widely deployed, and fully automatic machine translation is presently neither sufficiently fast nor sufficiently accurate to adequately support interactive cross-language information seeking. An active and rapidly growing research community has coalesced around these and other related issues, applying techniques drawn from several fields - notably information retrieval and natural language processing - to provide access to large multilingual collections.

    Abstract
    As digital libraries become a major source of information for many people, we need to know more about how people seek and retrieve information in digital environments. Quite commonly, users with a problem-at-hand and associated question-in-mind repeatedly search a literature for answers, and seek information in stages over extended periods from a variety of digital information resources. The process of repeatedly searching over time in relation to a specific, but possibly an evolving information problem (including changes or shifts in a variety of variables), is called the successive search phenomenon. The study outlined in this paper is currently investigating this new and little explored line of inquiry for information retrieval, Web searching, and digital libraries. The purpose of the research project is to investigate the nature, manifestations, and behavior of successive searching by users in digital environments, and to derive criteria for use in the design of information retrieval interfaces and systems supporting successive searching behavior. This study includes two related projects. The first project is based in the School of Library and Information Sciences at the University of North Texas and is funded by a National Science Foundation POWRE Grant <http://www.nsf.gov/cgi-bin/show?award=9753277>. The second project is based at the Department of Information Studies at the University of Sheffield (UK) and is funded by a grant from the British Library <http://www.shef. ac.uk/~is/research/imrg/uncerty.html> Research and Innovation Center. The broad objectives of each project are to examine the nature and extent of successive search episodes in digital environments by real users over time. The specific aim of the current project is twofold: * To characterize progressive changes and shifts that occur in: user situational context; user information problem; uncertainty reduction; user cognitive styles; cognitive and affective states of the user, and consequently in their queries; and * To characterize related changes over time in the type and use of information resources and search strategies particularly related to given capabilities of IR systems, and IR search engines, and examine changes in users' relevance judgments and criteria, and characterize their differences. The study is an observational, longitudinal data collection in the U.S. and U.K. Three questionnaires are used to collect data: reference, client post search and searcher post search questionnaires. Each successive search episode with a search intermediary for textual materials on the DIALOG Information Service is audiotaped and search transaction logs are recorded. Quantitative analysis includes statistical analysis using Likert scale data from the questionnaires and log-linear analysis of sequential data. Qualitative methods include: content analysis, structuring taxonomies; and diagrams to describe shifts and transitions within and between each search episode. Outcomes of the study are the development of appropriate model(s) for IR interactions in successive search episodes and the derivation of a set of design criteria for interfaces and systems supporting successive searching.

    Abstract
    There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This paper discusses a matching function for compound descriptors, or multi-concept subject headings, that does not rely an exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based an a measure of semantic closeness between terms, which has the potential to help with recall problems. The work reported is part of the ongoing FACET project in collaboration with the National Museum of Science and Industry and its collections database. The architecture of the prototype system and its Interface are outlined. The matching problem for compound descriptors is reviewed and the FACET implementation described. Results are discussed from scenarios using the faceted Getty Art and Architecture Thesaurus. We argue that automatic traversal of thesaurus relationships can augment the user's browsing possibilities. The techniques can be applied both to unstructured multi-concept subject headings and potentially to more syntactically structured strings. The notion of a focus term is used by the matching function to model AAT modified descriptors (noun phrases). The relevance of the approach to precoordinated indexing and matching faceted strings is discussed.

    Abstract
    The current subject gateways have evolved over time when the discipline of Internet resource discovery was in its infancy. This is reflected by the lack of well-established, light-weight, deployable, easy-to-use, standards for metadata and information retrieval. We provide an introduction to the architecture, standards and software solutions in use by subject gateways, and to the issues that must be addressed to support future subject gateways

    Abstract
    Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

    Abstract
    CORC is an OCLC project that id developing tools and systems to enable libraries to provide enhanced access to Internet resources. By adapting and extending library techniques and procedures, we are developing a self-supporting system capable of describing a large and useful subset of the Web. CORC is more a system for hosting and supporting subject gateways than a gateway itself and relies on large-scale cooperation among libraries to maintain a centralized database. By supporting emerging metadata standards such as Dublin Core and other standards such as Unicode and RDF, CORC broadens the range of libraries and librarians able to participate. Current plans are for OCLC as a full service in July 2000

    Abstract
    Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

    Abstract
    Even as the number of Web-enabled resources and knowledge repositories continues its unabated climb, both general purpose and domain-specific metadata schemas are in vigorous development. While this might be viewed as a promising direction for more precise access to disparate metadata-enabled resources, semantically-oriented tools to facilitate cross-domain searching by end-users unfamiliar with structured approaches to language or particular metadata schema conventions have received little attention. This paper describes findings from a focus group assessment of a natural language "gateway" previously derived from mapping, then categorizing terminology from nine metadata schemas. Semantic ambiguities identified in relation to three core metadata elements, namely, "Names", "Title", and "Subject", are discussed relative to data collection techniques employed in the research. Implications for further research, and particularly that pertaining to the design of an Interlingua gateway to multilingual, metadata-enabled resources, are addressed.

    Abstract
    This article describes two approaches for searching heterogeneous resources, which are explained as they are used in two corresponding existing systems-RIRS (Resource Integration Retrieval System) and HRUSP (Heterogeneous Resource Union Search Platform). On analyzing the existing systems, a possible framework-the MUSP (Multimetadata-Based Union Search Platform) is presented. Libraries now face a dilemma. On one hand, libraries subscribe to many types of database retrieval systems that are produced by various providers. The libraries build their data and information systems independently. This results in highly heterogeneous and distributed systems at the technical level (e.g., different operating systems and user interfaces) and at the conceptual level (e.g., the same objects are named using different terms). On the other hand, end users want to access all these heterogeneous data via a union interface, without having to know the structure of each information system or the different retrieval methods used by the systems. Libraries must achieve a harmony between information providers and users. In order to bridge the gap between the service providers and the users, it would seem that all source databases would need to be rebuilt according to a uniform data structure and query language, but this seems impossible. Fortunately, however, libraries and information and technology providers are now making an effort to find a middle course that meets the requirements of both data providers and users. They are doing this through resource integration.

    Abstract
    Purpose - The purpose of this paper is to report an investigation into the ways in which Canadian digital library collections have incorporated knowledge organization systems into their search interfaces. Design/methodology/approach - A combination of data-gathering techniques was used. These were as follows: a review of the literature related to the application of knowledge organization systems, deep scanning of Canadian governmental and academic institutions web sites on the web, identify and contact researchers in the area of knowledge organization, and identify and contact people in the governmental organizations who are involved in knowledge organization and information management. Findings - A total of 33 digital collections were identified that have made use of some type of knowledge organization system.
