Abstract

Links commonly refer to models developed for the World Wide Web Consortium, but these are a special case within the wider field of links and references used in resource discovery, including subject indexes to classifications, relationships used in vocabulary control, and search term recommender services. There is a tension between standardised relationships (symbolized by Paul Otlet's modernist universalism and the Semantic Web) and the particular, subjective situations in which individuals try to make sense (symbolized by Ludwik Fleck's emphasis on the influence of local cultural contexts). A subject index to a classification is a collection of links, sometimes qualified by context. Different domains (specialties) have their own cultural contexts and benefit from differently tailored links even when searching within the same resources. Making links is a descriptive, language activity. Probabilistic methods can create links from familiar to unfamiliar vocabularies economically. Links commonly use a limited set of relationships, mainly equivalence, inclusion, and inheritance. A far wider range of relationships would help resource discovery. Extending resource discovery requires not only same-facet links to reach additional resources but also links across different facets to provide explanatory context.

Abstract

iWe live in an information society, or so we are often told. But what does that mean? This volume in the MIT Press Essential Knowledge series offers a concise, informal account of the ways in which information and society are related and of our ever-increasing dependence on a complex multiplicity of messages, records, documents, and data. Using information in its everyday, nonspecialized sense, Michael Buckland explores the influence of information on what we know, the role of communication and recorded information in our daily lives, and the difficulty (or ease) of finding information. He shows that all this involves human perception, social behavior, changing technologies, and issues of trust. Buckland argues that every society is an "information society"; a "non-information society" would be a contradiction in terms. But the shift from oral and gestural communication to documents, and the wider use of documents facilitated by new technologies, have made our society particularly information intensive. Buckland describes the rising flood of data, documents, and records, outlines the dramatic long-term growth of documents, and traces the rise of techniques to cope with them. He examines the physical manifestation of information as documents, the emergence of data sets, and how documents and data are discovered and used. He explores what individuals and societies do with information; offers a basic summary of how collected documents are arranged and described; considers the nature of naming; explains the uses of metadata; and evaluates selection methods, considering relevance, recall, and precision.

Abstract

Presents the design of a prototype adaptive online catalogue. Online catalogue searches commonly retrieve too few or too many items. The prototype, implemented as a transparent workstation based front end to a MELVYL online catalogue of the holdings of the 9 campuses of California Universities, adapts to excessive or insufficient retrieval by strategically limiting, sorting or expanding users' searches, based on preferences defined by the user

Abstract

The growing number and sophistication of online bibliographic and networked based information systems is starting to blur the once clear boundaries that separated print documents. 2 concepts emerge as a consequence of these developments, first the 'union record', an entity which combines multiple catalog records for a single bibliographic item into an extended information object; and 2nd, an information 'dossier', a hypertext-like information object built by linking several distinct but related bibliographic entites

Abstract

Bibliographies and their knowledge organization systems commonly cover broad topical areas. Indexes to knowledge organization systems, such as the Subject Index to the Dewey Decimal Classification, provide a general index to the entirety. However, every community and every specialty develops its own specialized vocabulary. An index derived from the specialized use of language within a single subdomain could well be different from a general-purpose index for all domains and preferable for that subdomain. Statistical association techniques can be used to create indexes to knowledge systems. A preliminary analysis based on the INSPEC database shows that subdomain indexes differ significantly from each other and from a general index. The greater the polysemy of individual words the greater difference in the indexes
