Notes applications of information technology in archival activity, highlighting computer use in management of records centers and archives, intellectual control including computer indexing and online retrieval, and preservation of machine-readable records. Cooperative development of archival systems and impact of mini- and microcomputers are…

Analyzes the nature of Boolean information retrieval in relation to the discrete weights of query terms, examines assigned weights from an approach involving thresholds, and generates an evaluation mechanism which allows the user to attach a threshold to the query term. Thirteen references are listed. (FM)

Discusses the basic issues and practices in the administration of photographic collections, specifically with respect to the preservation of photographic materials, the organization of photographic files, and the cataloging of photographs under the Anglo American Cataloging Rules. An 18-item bibliography is included. (JL)

Uses an experimental system for authority control on a collection of bibliographic records to demonstrate the resemblance between thesaurus-based automatic indexing and automatic authority control. Details of the automatic indexing system are given, results discussed, and the benefits of the resemblance examined. Included are a rules appendix and…

Describes XMARC, a set of computer programs which provides students with a simplified means of writing programs for the automatic indexing of an experimental collection of MARC records. (Author/FM)

Describes an automatic method, based upon a text structure analysis and using a relatively small dictionary, to extract significant phrases from the title and the abstract of scientific and technical documents. The information representation of the document is discussed with relation to the construction of the document information retrieval…

Demonstrates that the process of comparing each document in an automated system with all others during the classification procedure may be avoided by the use of an inverted file. (FM)

Describes the implementation of a user-oriented online indexing system at the Boys Town Center's Library Services Division. (FM)

Responds to W. S. Cooper's article on utility-theoretic indexing (Journal of the American Society for Information Science, v29 n3) and posits that the method's claim to predictive success rests solely on its appeal to the consequences of decisions. (FM)

Answers Patrick Wilson's criticism of the theory of utility-theoretic indexing (Journal of the American Society for Information Science, v30 n3) and defends the theory on the basis of its analytic capability. (FM)

An on-line document retrieval system is described which combines a data base management system with automatic processing of natural language queries and abstracts. (Author)

A comparison of the Magazine Index (MI) and the New York Times Information Bank (IB) showed the two data bases have little in common, mainly due to differences in focus, indexing, vocabulary, use online, and output. For business and government users, IB is the best choice; for more general and academic purposes, MI provides access to more…

Argues that online indexing has great potential as a tool for information retrieval, and can be most effective when approached as a combination of traditional indexing and computer search capabilities. Argues that a good online index is specifically designed to be searched. Offers an overview of how to design such an online index. (SR)

Discussion of multimedia libraries and the need for storage, indexing, and retrieval techniques focuses on the combination of computer vision and data mining techniques to model high-level concepts for image retrieval based on perceptual features of the human visual system. Uses fuzzy set theory to measure users' assessments and to capture users'…

Discussion of weighted index terms in information retrieval focuses on a method for adjusting index weights by processing text in digital libraries that has been highlighted by users. Considers weights in query processing; feedback sources; active reading while accessing digital documents; collaborative information retrieval; and improving index…
