Describes a microcomputer-based string index format generated from concept networks using multiple search terms. Link weighting is highlighted as a method to decide which term appears first so the entry reflects the classification implied by the search specification. The computer software used for this system is briefly described. (Author/LRW)

Some of the factors that must inevitably affect the assessment of printed indexes are discussed, together with the observation of two unexpected phenomena, namely an apparent relationship between precision and searching effort, and relationships between generality and both recall and fallout.

Describes a study that examined the rates of use of descriptors in the ERIC (Educational Resources Information Center) system during 1966-86 to determine whether certain levels of terms were used more than others and whether patterns of use were similar among hierarchies in the ERIC Thesaurus.

Describes research designed to improve automatic pre-coordinate term indexing by applying language analysis techniques to identify term sources in requests, and to generate variant expressions of concepts involved for document text searching. Text analysis, term extraction, variant generation, and retrieval trial are highlighted. Thirteen…

Indexing is the preprocessing of information to enable its retrieval, ranging from classification-based (precoordinate) to keyword searching (postcoordinate) approaches. This article describes a framework for modelling information retrieval systems in terms of sets of objects, relationships, and functions and discusses the application of indexing…

Reviews previous work on producing knowledge by the use of information retrieval or classification schemes, and describes techniques by which hidden knowledge may be retrieved, i.e., serendipity in browsing and use of appropriate search strategies. Possible future methods based on relational indexing or artificial intelligence are also explored.…

Describes the development and evaluation of a new classification system for fiction which is based on an analysis of users' formulations of needs. Problems of concept identification (author's intention, citation order, vocabulary control, and choice of access terms) are highlighted. Examples of questions used in retrieval tests and 20 references…

Describes the indexing concept of entry terms, and evaluates existing terms in the Medical Subject Headings by comparing them to the results of an automatic indexer. The results of experimental testing of a strategy for creating entry terms using the algorithms of the automatic indexer are presented. (31 references) (CLB)

The Simple Index Method overcomes the difficulties in building a core list for serials in interdisciplinary fields by using multiple indexes which cover various aspects of the subject. Collection-development librarians can develop a core list when standard bibliographies or specific indexing and abstracting tools are lacking and can tailor that…

Addresses problems with automated bibliographic and full-text storage of scientific articles. The role of the scientific article is described, the structure is explained, current indexing and information retrieval techniques are criticized, new possibilities using a rhetoric syntax or argumentational syntax are explored, and the use of hypertext…
