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

Since information science concerns the transmission of records, it concerns context. The transmission of documents ensures their arrival in new contexts. Documents and their copies are spread across times and places. The amount of labor required to discover and retrieve relevant documents is also formulated by context. Thus, any serious consideration of communication and of information technologies quickly leads to a concern with context, relevance, and labor. Information scientists have developed many theories of context, relevance, and labor but not a framework for organizing them and describing their relationship with one another. We propose the words context and relevance can be used to articulate a useful framework for considering the diversity of approaches to context and relevance in information science, as well as their relations with each other and with labor.

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

Abstract

A recent article by Joseph Buschman regrets that democratic theory is an unfinished idea. The argument appears to assume an essential relationship between library and information science (LIS) and democratic theory. Libraries services are important for undemocratic purposes also, and like other sociotechnical systems, partake on the cultural context in which they are deployed.

Abstract

NISO draft standard Z39.50 (sometimes called the "Linked Systems Protocol") provides a standard for linking computers to permit the searching and retrieval of machine-readable bibliographic and authority records. The concept, context, status, and potential of the Linked Systems Protocol are reviewed in relation to the historical development of bibliographies and library catalogs. The functions of a fully developed bibliographic Linked Systems Protocol are summarized and shown to have extensive implications for scholarship, bibliographic access, and the notion of a national database. Effective international use of such a protocol would require the solution of several traditional problems.

Abstract

Purpose - The paper aims to explain the character and causes of obsolescence in assigned subject descriptors. Design/methodology/approach - The paper takes the form of a conceptual analysis with examples and reference to existing literature. Findings - Subject description comes in two forms: assigning the name or code of a subject to a document and assigning a document to a named subject category. Each method associates a document with the name of a subject. This naming activity is the site of tensions between the procedural need of information systems for stable records and the inherent multiplicity and instability of linguistic expressions. As languages change, previously assigned subject descriptions become obsolescent. The issues, tensions, and compromises involved are introduced. Originality/value - Drawing on the work of Robert Fairthorne and others, an explanation of the unavoidable obsolescence of assigned subject headings is presented. The discussion relates to libraries, but the same issues arise in any context in which subject description is expected to remain useful for an extended period of time.

Abstract

The transition from searching in a single database to searching a multiplicity of networked databases exacerbates some old difficulties in the design and evaluation of retrieval systems and creates new one. A networked environment calls into question the traditional definitions of recall and relevance. Efficient network searching raises questions about where to look first, where to look next and when to stop searching. The need for 'entry vocabulary' support and the need for support in moving from one system vocabulary to another are increased by the increased use of more different databases. The network environment offers the option of collecting different representations of the same object and merging them into an extended record
