Abstract

State of the art reviews coveruing a range of topics relating to small business information work, including: the relationship between small businesses and information sources and providers available to them; the use of information by small businesses; the state of the information technology adoption process by small businesses; and changes in small business information use. Concludes with a discussion about future research in the field and includes hypotheses about the impact of information access and technology on small businesses. Pays particular attention to the likely changes that are likely to take place in the small business environment, involving: telecommuting; and the electronic delivery of customized, timely environmental scanning information that will permit small businesses to function like big businesses. Decries the absence of effective links between small businesses and the information brokering world but sees small businesses taking advantage of some of the new lower cost online services that are being offered through the Internet

Abstract

This paper reviews the enormous changes in cataloging and classification reflected in the literature of 2003 and 2004, and discusses major themes and issues. Traditional cataloging and classification tools have been re-vamped and new resources have emerged. Most notable themes are: the continuing influence of the Functional Requirements for Bibliographic Control (FRBR); the struggle to understand the ever-broadening concept of an "information entity"; steady developments in metadata-encoding standards; and the globalization of information systems, including multilinguistic challenges.

Abstract

Presents a selective literature review covering the process of browsing as a means of searching for information. References are selected in order to illustrate the major themes and to bring out points which have not been emphasised before. The main points covered in the review include: consideration of browsing as an important, but under rated and little understood, form of information access; the ability in browsing to find analogies, connections, and new lines of thought; the potential of browsings as an ideal technique for accasional or non expert users; the ability to apply browsing to both paper based and computerized information retrieval; and the ability to search for information in a semi-random fashion leading to serendipitous linkage. Concludes that, despite the acknowledges importance of browsing, the increased effort being expended in making computerized systems browsable and the many references to the concept in the computer literature, there is still a lack of real understanding of the basic concepts of the process

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

The topic of electronic journals (e-journals) dominated the serials literature from 2000 to 2003. This review is limited to the events and issues within the broad topics of cost, management, and archiving. Coverage of cost includes such initiatives as PEAK, JACC, BioMed Central, SPARC, open access, the "Big Deal," and "going e-only." Librarians combated the continued price increase trend for journals, fueled in part by publisher mergers, with the economies found with bundled packages and consortial subscriptions. Serials management topics include usage statistics; core title lists; staffing needs; the "A-Z list" and other services from such companies as Serials Solutions; "deep linking"; link resolvers such as SFX; development of standards or guidelines, such as COUNTER and ERMI; tracking of license terms; vendor mergers; and the demise of integrated library systems and a subscription agent's bankruptcy. Librarians archived print volumes in storage facilities due to space shortages. Librarians and publishers struggled with electronic archiving concepts, discussing questions of who, where, and how. Projects such as LOCKSS tested potential solutions, but missing online content due to the Tasini court case and retractions posed more archiving difficulties. The serials literature captured much of the upheaval resulting from the rapid pace of changes, many linked to the advent of e-journals.

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

This chapter examines the nature of semantic relations and their main applications in information science. The nature and types of semantic relations are discussed from the perspectives of linguistics and psychology. An overview of the semantic relations used in knowledge structures such as thesauri and ontologies is provided, as well as the main techniques used in the automatic extraction of semantic relations from text. The chapter then reviews the use of semantic relations in information extraction, information retrieval, question-answering, and automatic text summarization applications. Concepts and relations are the foundation of knowledge and thought. When we look at the world, we perceive not a mass of colors but objects to which we automatically assign category labels. Our perceptual system automatically segments the world into concepts and categories. Concepts are the building blocks of knowledge; relations act as the cement that links concepts into knowledge structures. We spend much of our lives identifying regular associations and relations between objects, events, and processes so that the world has an understandable structure and predictability. Our lives and work depend on the accuracy and richness of this knowledge structure and its web of relations. Relations are needed for reasoning and inferencing. Chaffin and Herrmann (1988b, p. 290) noted that "relations between ideas have long been viewed as basic to thought, language, comprehension, and memory." Aristotle's Metaphysics (Aristotle, 1961; McKeon, expounded on several types of relations. The majority of the 30 entries in a section of the Metaphysics known today as the Philosophical Lexicon referred to relations and attributes, including cause, part-whole, same and opposite, quality (i.e., attribute) and kind-of, and defined different types of each relation. Hume (1955) pointed out that there is a connection between successive ideas in our minds, even in our dreams, and that the introduction of an idea in our mind automatically recalls an associated idea. He argued that all the objects of human reasoning are divided into relations of ideas and matters of fact and that factual reasoning is founded on the cause-effect relation. His Treatise of Human Nature identified seven kinds of relations: resemblance, identity, relations of time and place, proportion in quantity or number, degrees in quality, contrariety, and causation. Mill (1974, pp. 989-1004) discoursed on several types of relations, claiming that all things are either feelings, substances, or attributes, and that attributes can be a quality (which belongs to one object) or a relation to other objects.
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.

Abstract

What is an electronic record, how should it best be preserved and made available, and to what extent do traditional, paradigmatic archival precepts such as provenance, original order, and archival custody hold when managing it? Over more than four decades of work in the area of electronic records (formerly known as machine-readable records), theorists and researchers have offered answers to these questions-or at least devised approaches for trying to answer them. However, a set of fundamental questions about the nature of the record and the applicability of traditional archival theory still confronts researchers seeking to advance knowledge and development in this increasingly active, but contested, area of research. For example, which characteristics differentiate a record from other types of information objects (such as publications or raw research data)? Are these characteristics consistently present regardless of the medium of the record? Does the record always have to have a tangible form? How does the record manifest itself within different technological and procedural contexts, and in particular, how do we determine the parameters of electronic records created in relational, distributed, or dynamic environments that bear little resemblance an the surface to traditional paper-based environments? At the heart of electronic records research lies a dual concern with the nature of the record as a specific type of information object and the nature of legal and historical evidence in a digital world. Electronic records research is relevant to the agendas of many communities in addition to that of archivists. Its emphasis an accountability and an establishing trust in records, for example, addresses concerns that are central to both digital government and e-commerce. Research relating to electronic records is still relatively homogeneous in terms of scope, in that most major research initiatives have addressed various combinations of the following: theory building in terms of identifying the nature of the electronic record, developing alternative conceptual models, establishing the determinants of reliability and authenticity in active and preserved electronic records, identifying functional and metadata requirements for record keeping, developing and testing preservation
