Analyzes associations among different role operators quantitatively by taking input strings from 200 abstracts, each related to subject fields of taxation, genetic psychology, and Shakespearean drama, and subjecting them to the Chi-square test. Significant associations by other differencing operators and connectives are discussed. A schema of role…

Describes applications in variety of settings of videodiscs as tools of information retrieval with online databases, identifies underlying technical capabilities, and discusses five operations required to implement any application: coordinating diverse formats; indexing; physically arranging items on disc; designing input, search, and output;…

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…

Demonstrates efficiency of preparation of query description using semantic analyser method based on analysis of semantic structure of documents in field of automatic indexing. Results obtained are compared with automatic indexing results performed by traditional methods and results of indexing done by human indexers. Sample terms and codes are…

Review for workers in information science of the development of Permuterm Subject Index (PSI) of the Science Citation Index (SCI). (KP)

This paper presents the most important concepts and techniques to use in successfully searching the major World Wide Web search engines and directories, explains the basics of how search engines work, and describes what is included in their indexes. Following an introduction that gives an overview of Web directories and search engines, the first…

This paper focuses on a user driven approach to improve video indexing. It consists in cumulating the large amount of small, individual efforts done by the users who access information, and to provide a community management mechanism to let users share the elicited knowledge. This technique is currently being developed in the "OPALES"…

The purpose of this research is to investigate indexing issues that pertain to the development of digital libraries, including: the identification of sublanguage vocabulary; domain-specific indexing; and other indexing tools. Thesauri are needed for digital libraries in order to improve end-user access. To demonstrate the importance of thesauri to…

An evaluation of graph theoretical clusters of index terms which can be extracted from an automatically indexed document collection, and the effects of employing such clusters in automatic document retrieval are described. (19 references) (Author)

This brief overview of some vocabulary control schemes in non-scientific fields is intended to suggest that the complexity of the design problem increases with the newness of the field involved. (Author/NH)

Some problems encountered with the ERIC indexing system in efforts to retrieve information from the ERIC files are discussed. (4 references) (Author/NH)

Reviews characteristics and efficiency of types of information retrieval systems, and concludes that for selective dissemination of information from computer tapes keyword indexing is less efficient than enumerative hierarchical systems which require single hit searching. (AL)

A method for producing course reading lists as an outgrowth of ongoing research in indexing is described. (AB)

Results of this study comparing coverage and features of Psychological Abstracts and National Institute of Mental Health (NIMH) online databases demonstrate a 49 percent citation overlap between the files. A complementary, not competitive, relationship is indicated by comparing citation overlap, journal coverage, descriptive indexing, treatment of…

Considers patent subject searching capabilities of major online databases, noting patent claims, "deep-indexed" files, test searches, retrieval of related references, multi-database searching, improvements needed in indexing of chemical structures, full text searching, improvements needed in handling numerical data, and augmenting a…
