Younger, Jennifer A. – Library Resources and Technical Services, 1982
Presents a selective review of works in 1981 concerned with subject access to information sources, with specific discussions devoted to general and theoretical works, vocabulary management, classification schemes, subject headings, indexing, and automatic indexing and classification. A 110-item bibliography is included. (JL)

Fidel, Raya – Journal of the American Society for Information Science, 1994
Distinguishes between document-oriented and user-oriented indexing and discusses the advantages and disadvantages of request-oriented and automated indexing. Request-oriented indexing is difficult to implement with human, a priori indexing. Automated indexing can be tailored to individual requests, but most research in this area focuses on global…

Wellisch, Hans H. – Library Resources and Technical Services, 1981
Reviews contributions by scholars and institutions in the fields of classification, subject headings, thesauri, indexing, abstracting, and automatic classification and indexing. Also included are works exploring the theoretical foundations of subject analysis and the history of indexing and abstracting. There are 111 references. (RAA)

Milstead, Jessica L. – Information Processing and Management, 1992
Examines current activities in subject analysis of large bibliographic databases to assist database managers in making cost-effective decisions. Issues addressed include manual indexing aids, automatic indexing, and connecting indexing terms. Several software packages are described, and future research directions are suggested. (58 references)…

Milstead, Jessica L. – Journal of the American Society for Information Science, 1994
Uncovers issues in indexing that need scientific research, including the cognitive processes of indexers and users; vocabulary control; how best to supplement human indexers' intellectual effort with computer capabilities; structure and layout of indexes on the printed page and on the computer screen; and evaluation of indexes. (Contains 21…

Srinivasan, Padmini – Journal of the American Society for Information Science, 1990
After reviewing the literature on automatic indexing research an experiment is described which examined term distribution and the effectiveness of the Two Poisson and Three Poisson Models in identifying good index terms. The conclusion reached is that these models should be applied with caution in document retrieval. (25 references) (EAM)

Salton, Gerard – Journal of the American Society for Information Science, 1987
Briefly reviews early work in documentation and text processing, and predictions that were made about the creative role of computers in information retrieval. An attempt is made to explain why these predictions were not fulfilled and conclusions are drawn regarding the limits of computer power in text retrieval applications. (Author/CLB)
Descriptors: Automatic Indexing, Documentation, Information Retrieval, Information Technology

Bell, Colin; Jones, Kevin P. – Journal of the American Society for Information Science, 1979
Surveys the current state of minicomputer-operated information systems capable of incorporating linguistic features, focusing on the Minicomputer Operated Retrieval (Partially Heuristic) System. Consideration is given to the automation of the indexing process and to available search strategies. (FM)

Harter, Stephen P. – Drexel Library Quarterly, 1978
Views automatic indexing as a two-tiered word frequency analysis that involves selection of a technical vocabulary and identification of document keywords. Assumptions, criteria, evaluation, and relevance are discussed. (JD)
Descriptors: Automatic Indexing, Bibliographies, Criteria, Evaluation

Salton, Gerard; And Others – Information Processing and Management, 1990
Summarizes various linguistic approaches proposed for document analysis in information retrieval environments. Topics discussed include syntactic analysis; use of machine-readable dictionary information; knowledge base construction; the PLNLP English Grammar (PEG) system; phrase normalization; and statistical and syntactic phrase evaluation used…

Burke, Colin – Journal of the American Society for Information Science, 1992
Presents an historical overview of Vannevar Bush's efforts to develop a machine for free-form indexing and computerized information retrieval. Descriptions of the Memex concept and two related machines--the Rapid Selector and the Comparator--are provided; and the shift in emphasis to a device for business or cryptanalytic purposes is discussed.…

Harman, Donna; Candela, Gerald – Journal of the American Society for Information Science, 1990
Describes the advantages of a prototype retrieval system that uses statistically based ranked retrieval of records rather than traditional boolean methods, especially for end users. Several new techniques are also discussed including bit mapping, pruning, methods of building inverted files, and types of search engine. (26 references) (EAM)

Gomez, Louis M.; And Others – Journal of the American Society for Information Science, 1990
Reports on a study of index term selection techniques in a small experimental keyword information retrieval system. Two experiments are described which show that user success is improved by increasing the number of terms per object used. Implications for larger databases are considered. (22 references) (EAM)
Descriptors: Automatic Indexing, Databases, Online Searching, Relevance (Information Retrieval)

Fagan, Joel L. – Journal of the American Society for Information Science, 1989
Describes the possible improvements in the quality of automatic indexing systems gained by using complex descriptors, and reports on the effectiveness of a simple nonsyntactic phrase indexing procedure. The discussion covers shortcomings of this approach, possible methods for improvement, and areas needing further research. (43 references) (CLB)

Purcell, Royal – Library Software Review, 1991
Discussion of indexing focuses on the possibilities of fully automated indexing. Topics discussed include controlled indexing languages such as subject heading lists and thesauri, free indexing languages, natural indexing languages, computer-aided indexing, expert systems, and the need for greater creativity to further advance automated indexing.…
