    Abstract
    The Digital Library Federation is a consortium of research libraries and related organizations in the United States that are pioneering in the use of electronic-information technologies. Each of the DLF's members, mostly research libraries, contributes to a capital fund and an annual budget to support the organization, which is administered by a directorate within the U.S. Council an Library and Information Resources. A Steering Committee, on which each member Institution is represented, guides the work, which has focused an coordinating research, identifying standards and »best practices« for digital library development, and helping to start projects that libraries need but cannot easily develop individually.The DLF convenes task forces, issues publications, sponsors a biannual Digital Library Forum, and maintains a Web site.

    Abstract
    We propose an extension of a mediator architecture. This extension is oriented to ontology-driven data integration. In our architecture ontologies are not managed by an extemal component or service, but are integrated in the mediation layer. This approach implies rethinking the mediator design, but at the same time provides advantages from a database perspective. Some of these advantages include the application of optimization and evaluation techniques that use and combine information from all abstraction levels (physical schema, logical schema and semantic information defined by ontology). 1. Introduction Although the Web is probably the richest information repository in human history, users cannot specify what they want from it. Two major problems that arise in current search engines (Heflin, 2001) are: a) polysemy, when the same word is used with different meanings; b) synonymy, when two different words have the same meaning. Polysemy causes irrelevant information retrieval. On the other hand, synonymy produces lost of useful documents. The lack of a capability to understand the context of the words and the relationships among required terms, explains many of the lost and false results produced by search engines. The Semantic Web will bring structure to the meaningful content of Web pages, giving semantic relationships among terms and possibly avoiding the previous problems. Various proposals have appeared for meta-data representation and communication standards, and other services and tools that may eventually merge into the global Semantic Web (Berners-lee, 2001). Hopefully, in the next few years we will see the universal adoption of open standards for representation and sharing of meta-information. In this environment, software agents roaming from page to page can readily carry out sophisticated tasks for users (Berners-Lee, 2001). In this context, ontologies can be seen as metadata that represent semantic of data; providing a knowledge domain standard vocabulary, like DTDs and XML Schema do. If its pages were so structured, the Web could be seen as a heterogeneous collection of autonomous databases. This suggests that techniques developed in the Database area could be useful. Database research mainly deals with efficient storage and retrieval and with powerful query languages.

    Abstract
    Barrierefreiheit von Websites hat viele Aspekte und bedeutet mehr als "Internet für Blinde": Ein guter Einstieg ist, sich auf die ursprünglichen Standards von HTML zu besinnen. Doch erst mit einem umfassenden Blick auf das Nutzerverhalten kann man Online-Angebote zielgruppengerecht optimieren. Ein Content-Management-System hilft dabei - vor, allem, wenn es seinerseits auf Standards wie XML basiert.

    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
    The U.S. federal government has been a major publisher on the Internet. Its many agencies have used the Internet, and the Web most recently, to provide access to a great quantity of their information output. Several agencies such as the Library of Congress and the Government Printing Office have taken a leading role in both providing information and offering finding aids, while other endeavors such as FirstGov and subject gateways offer other avenues of access. A brief look back at the history of the government on the Web and the continuing concerns and challenges show how the government is not only a major content provider on the Internet but also a source for the organization of the content.

    Abstract
    Users of the Information Superhighway need signposts to find their way to appropriate, accurate and current information. Given the sheer quantity of information, intellectual indexing is more relevant than ever, complementing and augmenting automatic keyword indexing. Signposts come in various forms including browser bookmarks, local, on-site and remote lists, indexes and directories, temporary search engine results, and metadata. The considerable body of theory on vocabulary control for online database searching can be adapted to index construction for the Internet. At the same time, there are unresolved issues concerning information quality, indexing decisions, and standards

    Abstract
    This article seeks to shift the literature an chat-based reference services beyond the current spate of case studies and discussions of emerging standards and best practices in providing chat-based reference, to a higher level of discussion an the creation and discussion of theoretical frameworks to unite these standards and practices. The article explores the varlous steps in the process of providing synchronous, chat-based reference, as well as issues involved in providing such service at each step. The purpose of this exploration is twofold: First, this article presents some open research questions at each step in the process of providing chatbased reference service. Second, the entire process of providing chat-based reference is viewed as a whole, and a model of the provision of chat-based reference service is developed at a high level of abstraction. lt is hoped that this model may serve as a conceptual framework for future discussions of and development of applications for chat-based reference.

    "Den Zusammenschluss von Radio, Fernsehen und Internet haben die Teilnehmer der Auftaktveranstaltung des medienforum nrw" für die nächsten fünf Jahre weitgehend 'ausgeschlossen. Im großen Rheinsaal der Köln-Messe sagte der Vorstandsvorsitzende der ProSiebenSatl.Media AG, Urs Rohner, dass er sehr skeptisch sei, was die Konvergenz von Internet und konventionellen Medien angehe. WDR-Intendant und Vorsitzender der ARD Fritz Pleitgen bestätigte: "Neben dem Internet wird es definitiv auch weiterhin Fernsehen und Radio geben." Und NRW-Ministerpräsident Wolfgang Clement ergänzte: "Alle bereiten sich auf die neuen Entwicklungen im Internet vor. Aber niemand weiß genau, wo es denn hingeht. Allerdings kann es sich auch niemand leisten, sich nicht vorzubereiten." Diese unsichere Lage, was die digitale Zukunft des Fernsehens betreffe, dürfe nicht dazu führen, so Pleitgen, dass das Publikum mit zusätzlichen Kosten belastet werde, ohne dass man genau wisse, wohin die Reise geht. "Wir müssen auf die Wünsche des Publikums achten. Nachher will das Internet-Fernsehen niemand", so der ARDChef. Gerade erst seien Großbritannien die Ergebnisse einer Umfrage veröffentlicht worden, der zu Folge 30 Prozent der Briten kein Interesse am InternetTV hätten, betonte Pleitgen". Unter der Moderation von RTLNachrichtenmann Peter Kloeppel diskutierten neben Rohner, Clement und Pleitgen noch Ewald Walgenbach, stellvertretender Vorstandsvorsitzender der RTL-Group, Norbert Schneider, Direktor der Landesanstalt für Rundfunk NRW, und der Kultur-Staatsminsiter Julian Nida-Rümelin über die Frage "Wohin steuert die Medienbranche?" Nida-Rümelin betonte in der Konvergenz-Frage zudem, dass er sich gegen die vollständige Kommerzialisierung des Internets wehre. Der anarchistische und interaktive Charme des Internets solle doch weitgehend erhalten bleiben, so der Professor der Philosophie. Zudem forderte Nida-Rümelin eine EthikDiskussion für die Zukunft des Fernsehens: "Wir müssen uns auf Standards in der Frage, was für jeden an Information zugängig sein muss, einigen." Hinsichtlich digitalen Fernsehens und Pay-TV fragte Kloeppel provokant, ob sich die Informationsfreiheit künftig auf die Reichen beschränken solle. Pleitgen zerstreute solche Bedenken mit Optimismus: Jm Kampf gegen Kirch und Bertelsmann haben wir bereits gute Erfahrungen gemacht." Am Ende waren sich alle einig, dass der Dualismus von öffentlich-rechtlichen Sendern und privaten Rundfunkanstalten auch zukünftig für Deutschland bestimmend sein müsse

    Abstract
    The proliferation of information in electronic format does not guarantee its accessibility. The fact that many Web sites are not accessible to large segments of the disabled community has created a "digital divide". The accessibility barriers are systemic. In recent years, there has been a growing body of significant laws and standards concerning Web accessibility that impact people with disabilities. Ways of breaking down these barriers to a fuller accessibility implementation do exist, including education to raise awareness of Web accessibility, nationwide policy and guidelines for accessibility, and Web-based applications and tools to facilitate Web accessibility, to name a few.

    Abstract
    This article discusses the history and emergence of non-library commercial and noncommercial information services on the World Wide Web. These services are referred to as "expert services," while the term "digital reference" is reserved for library-related on-line information services. Following suggestions in library and information literature regarding quality standards for digital reference, researchers make clear the importance of developing a practicable methodology for critical examination of expert services, and consideration of their relevance to library and other professional information services. A methodology for research in this area and initial data are described. Two hundred forty questions were asked of 20 expert service sites. Findings include performance measures such as response rate, response time, and verifiable answers. Sites responded to 70% of all questions, and gave verifiable answers to 69% of factual questions. Performance was generally highest for factual type questions. Because expert services are likely to continue to fill a niche for factual questions in the digital reference environment, implications for further research and the development of digital reference services may be appropriately turned to source questions. This is contrary to current practice and the emergence of digital reference services reported in related literature thus far.

    Abstract
    The title for this conference, stated in English, is Language Technology for a Dynamic Economy - y in the Media Age - The question arises as to what the media are we are dealing with and to what extent we are moving away from tile reality of different media to a world in which all sub-categories flow together into a unified stream of information that is constantly resealed to appear in different hardware configurations. A few years ago, people who were interested in sharing data or getting different electronic "boxes" to talk to each other were focused on two major aspects: I ) developing data conversion technology, and 2) convincing potential users that sharing information was an even remotely interesting option. Although some content "owners" are still reticent about releasing their data, it has become dramatically apparent in the Web environment that a broad range of users does indeed want this technology. Even as researchers struggle with the remaining technical, legal, and ethical impediments that stand in the way of unlimited information access to existing multi-platform resources, the future view of the world will no longer be as obsessed with conversion capability as it will be with creating content, with ,in eye to morphing technologies that will enable the delivery of that content from ail open-standards-based format such as XML (eXtensibic Markup Language), MPEG (Moving Picture Experts Group), or WAP (Wireless Application Protocol) to a rich variety of display Options

    Abstract
    Die »Charta der Bürgerrechte für eine nachhaltige Wissensgesellschaft« fordert einen an Nachhaltigkeitsprinzipien orientierten freizügigen und inklusiven Umgang mit Wissen und Information. Die Herausforderung der Wissensgesellschaft besteht darin, den Menschen das Wissen anderer über den Zugang zu Information offen zu halten und sie so auf einer sicheren Grundlage handlungsfähig zu machen.
    Content
    1. Wissen ist Erbe und Besitz der Menschheit und damit frei 2. Der Zugriff auf Wissen muss frei sein 3. Die Überwindung der digitalen Spaltung muss als Politikziel hoher Priorität anerkannt werden 4. Alle Menschen haben das Recht auf Kommunikation und Informationsfreiheit 5. Die Arbeitnehmer(innen)rechte müssen auch in der elektronisch vernetzten Arbeitswelt gewährleistet und weiterentwickelt werden 6. Kulturelle Vielfalt ist Bedingung für individuelle und nachhaltige gesellschaftliche Entwicklung 7. Mediale vielfalt und das Angebot von Information aus unabhängigen Quellen sind unerkässlich für den Erhalt eine aufgeklärten Öffentlichkeit 8. Offene technische Standards und offene Formen der technischen Produktion garantieren die freie Entwicklung der Infrastrukturen und somit eine selbst bestimmte und freie Kommunikation 9. Das Recht auf Achtung der Privatheit ist ein Menschenrecht und ist unabdingbar für die freie und selbst bestimmte Entfaltung von Menschen in der Wissensgesellschaft

    Abstract
    Purpose - The essential purpose of this paper is to measure the amount of web resources used for scholarly contributions in the area of library and information science (LIS) in India. It further aims to make an analysis of the nature and type of web resources and studies the various standards for web citations. Design/methodology/approach - In this study, the result of analysis of 292 web citations spread over 95 scholarly papers published in the proceedings of the National Conference of the Society for Information Science, India (SIS-2005) has been reported. All the 292 web citations were scanned and data relating to types of web domains, file formats, styles of citations, etc., were collected through a structured check list. The data thus obtained were systematically analyzed, figurative representations were made and appropriate interpretations were drawn. Findings - The study revealed that 292 (34.88 per cent) out of 837 were web citations, proving a significant correlation between the use of Internet resources and research productivity of LIS professionals in India. The highest number of web citations (35.6 per cent) was from .edu/.ac type domains. Most of the web resources (46.9 per cent) cited in the study were hypertext markup language (HTML) files. Originality/value - The paper is the result of an original analysis of web citations undertaken in order to study the dependence of LIS professionals in India on web sources for their scholarly contributions. This carries research value for web content providers, authors and researchers in LIS.

    Abstract
    Purpose - The purpose of this paper is to discuss alternative definitions of and approaches to the semantic web. It aims to clarify the relationship between the semantic web, Web 2.0 and Library 2.0. Design/methodology/approach - The paper is based on a literature review and evaluation of systems with semantic web features. It identifies and describes semantic web projects of relevance to libraries and evaluates the usefulness of JeromeDL and other social semantic digital library systems. It discusses actual and potential applications for libraries and makes recommendations for actions needed by researchers and practitioners. Findings - The paper concludes that the library community has a lot to offer to, and benefit from, the semantic web, but there is limited interest in the library community. It recommends that there be greater collaboration between semantic web researchers and project developers, library management systems providers and the library community. Librarians should get involved in the development of semantic web standards, for example, metadata and taxonomies. Originality/value - The paper clarifies the distinction between semantic web and Web 2.0 in a digital library environment. It evaluates and predicts future developments for operational systems.

    Abstract
    Examines two commitments inherent in Resource Description Framework (RDF): intertextuality and rationalism. After introducing how rationalism has been studied in knowledge organization, this paper then introduces the concept of bracketed-rationalism. This paper closes with a discussion of ramifications of intertextuality and bracketed rationalism an evaluation of RDF.

    Mit einer Übersicht zu Usability-Kriterien: Ten Usability Heuristics I. Visibility ofsystem status The system should always keep users informed about what is going on, through appropriate feedback within reasonable time. II. Match between system and the real world The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order. III. User control and freedom Users often choose system functions by mistake and will need a clearly marked »emergency extra to leave the unwanted state without having to go through an extended dialogue. Support undo and redo. IV. Consistency and standards Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions. V. Error prevention Even better than good error messages is a careful design which prevents a problem from occurring in the first place. VI. Recognition rather than recall Make objects, actions, and options visible. The user should not have to remember information from one Part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate. VII. Flexibility and efficiency of use Accelerators - unseen by the novice user- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions. VIII. Aesthetic and minimalist design Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility. IX. Help users recognize, diagnose, and recover from errors Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution. X. Help and documentation Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused an the user's task, list concrete steps to be carried out, and not be too large.

    Abstract
    This paper reflects on some major aspects related to library subject access systems in the era of networked information. The main argument builds on the fact that we nowadays witness the strongest demand and expectation on subject access tools, coming from far beyond the traditional library world, but the field remains the weakest side of international librarianship. While the emergence to cope with the practical challenges of a wider environment is emphasized, the need to reinforce the internationalization of knowledge organization as a professional library matter is stressed, not only at the pragmatic level but also, more importantly, in theoretical terms.

    Abstract
    Because of the nature, number, and extreme mobility of resources available on electronic networks, access instruments that will allow information seekers to find relevant Web pages or sites are essential. While virtual libraries without clear collection development policies continue to be established, ad hoc knowledge organization schemes also continue to be conceived and implemented; these so-called innovative classification tools are generally structured around loose categories representing a mix of disciplines, subjects, forms of presentation, and audiences. This paper discusses a few examples of Web-based organization schemes, suggesting that their degree of intuitiveness, user-friendliness and efficiency is very possibly overrated
