    Abstract
    With more than two billion pages created by millions of Web page authors and organizations, the World Wide Web is a tremendously rich knowledge base. The knowledge comes not only from the content of the pages themselves, but also from the unique characteristics of the Web, such as its hyperlink structure and its diversity of content and languages. Analysis of these characteristics often reveals interesting patterns and new knowledge. Such knowledge can be used to improve users' efficiency and effectiveness in searching for information an the Web, and also for applications unrelated to the Web, such as support for decision making or business management. The Web's size and its unstructured and dynamic content, as well as its multilingual nature, make the extraction of useful knowledge a challenging research problem. Furthermore, the Web generates a large amount of data in other formats that contain valuable information. For example, Web server logs' information about user access patterns can be used for information personalization or improving Web page design.

    Abstract
    Innovative Ideen setzen sich in den meisten Fällen schwer durch. Die elektronische Revolution erfordert neues Management und neue Organisation auf dem Informationsmarkt. Ein Instrument, das zunehmend an Bedeutung gewann, ist die ISBN Nummer, die jedem Buch seine Individualsignatur gibt und daher zur Globalisierung des Marktes beitrug. Hartmut Walravens hat die Entwicklung der ISBN maßgeblich beeinflusst, die durch die umfassende Bibliographie und einen Überblick dokumentiert wird.

    Abstract
    The emergence of digital libraries (DLs), at the interface of library and information science with computer and communication technologies, helped to expand significantly the literature in all of these areas during the late 1990s. The pace of development is reflected by the number of special issues of major journals in information science and computer science, and the increasing number of workshops and conferences an digital libraries. For example, starting in 1995, the Communications of the ACM has devoted three special issues to the topic (Fox, Akscyn, Furuta, & Leggett, 1995; Fox & Marchionini, 1998, 2001). The Journal of the American Society for Information Science devoted two issues to digital libraries (H. Chen, 2000; Fox & Lunin, 1993); Information Processing & Management and the Journal of Visual Communication and Image Representation each had one special issue (Chen & Fox, 1996; Marchionini & Fox, 1999). The domain of digital libraries, though still evolving, has matured over the last decade, as demonstrated by coverage through D-Lib (http://www.dlib.org), the International Journal an Digital Libraries (http://link.springer.de/link/service/journals/00799), and two overview works (W Y Arms, 2000; Lesk, 1997; both of which have also served as textbooks). Sun Microsystems published a small book to guide those planning a digital library (Noerr, 2000), and IBM has been developing commercial products for digital libraries since 1994 (IBM, 2000). A number of Web sites have extensive sets of pointers to information an DLs (D-Lib Forum, 2001; Fox, 1998a; Habing, 1998; Hein, 2000; Schwartz, 2001a, 2001b). Further, the field has attracted the attention of diverse academics, research groups, and practitionersmany of whom have attended tutorials, workshops, or conferences, e.g., the Joint Conference an Digital Libraries, which is a sequel to a separate series run by ACM and IEEE-CS. Therefore, it is timely that ARIST publishes this first review focusing specifically an digital libraries. There has been no ARIST chapter to date directly dealing with the area of DLs, though some related domains have been covered-particularly: information retrieval, user interfaces (Marchionini & Komlodi, 1998), social informatics of DLs (Bishop & Star, 1996), and scholarly communication (see Borgman and Furner's chapter in this volume). This chapter provides an overview of the diverse aspects and dimensions of DL research, practice, and literature, identifying trends and delineating research directions.

    Abstract
    Linguists in the structuralist tradition (e.g., Lyons, 1977; Saussure, 1959) have asserted that concepts cannot be defined on their own but only in relation to other concepts. Semantic relations appear to reflect a logical structure in the fundamental nature of thought (Caplan & Herrmann, 1993). Green, Bean, and Myaeng (2002) noted that semantic relations play a critical role in how we represent knowledge psychologically, linguistically, and computationally, and that many systems of knowledge representation start with a basic distinction between entities and relations. Green (2001, p. 3) said that "relationships are involved as we combine simple entities to form more complex entities, as we compare entities, as we group entities, as one entity performs a process on another entity, and so forth. Indeed, many things that we might initially regard as basic and elemental are revealed upon further examination to involve internal structure, or in other words, internal relationships." Concepts and relations are often expressed in language and text. Language is used not just for communicating concepts and relations, but also for representing, storing, and reasoning with concepts and relations. We shall examine the nature of semantic relations from a linguistic and psychological perspective, with an emphasis on relations expressed in text. The usefulness of semantic relations in information science, especially in ontology construction, information extraction, information retrieval, question-answering, and text summarization is discussed. Research and development in information science have focused on concepts and terms, but the focus will increasingly shift to the identification, processing, and management of relations to achieve greater effectiveness and refinement in information science techniques. Previous chapters in ARIST on natural language processing (Chowdhury, 2003), text mining (Trybula, 1999), information retrieval and the philosophy of language (Blair, 2003), and query expansion (Efthimiadis, 1996) provide a background for this discussion, as semantic relations are an important part of these applications.
