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

The OASIS project is undergoing a complete revision in order to give a flexible graphical interface, more powerful analysis tools, and broader searching capabilities. A new X Windows interface is being linked to a search and analysis backend written primarily in Emacs Lisp to take advantage of its advanced string processing functions and multiple buffering features

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

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.
