Abstract

By the mid 1980s online bibliographic systems retrieved excessively large sets. Conversely, with standard Boolean systems, searches retrieved commonly nothing or too few records. In Nov. 92, 32% of searches yielded nothing from a retrieval set averaging 98. Offers solutions to these problems using MELVYL as a case study. Examines how non topical data such as date, language and location of document can improve topical searches. Explains OASIS and front end phototyping. Discusses adaptive retrieval, strategic commands, expanded retrieval and developments of OASIS. Covers aggregation of filtered sets, related terms, automatic progressive truncation, the SUMMARIZE LIBRARIES command, filing and filtering and collection analysis

Abstract

State of the art review of the historical development of information science as deemed to be covered by the particular interests of memebers of the American Society for Information Science, as defined as the representation, storage, transmission, selection, retrieval, filtering, and use of documents and messages. Arranges the references cited roughly according to the classification scheme used by Information Science Abstracts, and so uses the headings: background; information science; techniques and technology; information related behaviour; application areas; social aspects; education for information science; institutions; individuals; geographical areas; and conclusions

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

Abstract

In the past information retrieval has been primarily concerned with text and text-like data. Image-handling is considered as a form of image retrieval and considers the pioneering work of Paul Otlet and Suzanne Briet. Concludes that the terminology of multimedia needs attention to distinguish phenomena, facts, representations, forms of expression, and physical medium

Abstract

Three meanings of "information" are distinguished: "information-as-process"; "information-as-knowledge"; and "information-as-thing", the attributive use of "information" to denote things regarded as informative. The nature and characteristics of "information-as-thing" are discussed, using an indirect approach ("What things are informative?"). Varieties of "information-as-thing"include data, text, documents, objects, and events. On this view "information" includes but extends beyond communication. Whatever information storage and retrieval systems store and retrieve is necessarily "information-as-thing"

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

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.
