Investigates techniques for automatic coding of English language strings which involve titles drawn from bibliographic files, but do not require prior knowledge of source. Coding methods (basic, maximum entropy principle), results of test using 6,260 titles from British National Bibliography, and variations in code element ordering are…

The structure of a retrospective information retrieval system that uses equifrequent word or text fragments is described, and its advantages over word oriented systems are mentioned briefly. (Author)

Introduced are information retrieval strategies based on automatic hierarchic clustering of documents. Cluster-based strategies are shown to be as effective as, and more efficient than, linear associative retrieval. (47 references) (Author/SJ)

A brief description of an efficient information retrieval system by which students, teachers, researchers, etc., may store information and data that are pertinent to their work. (AK)

Frequently it is useful to abbreviate or otherwise transform keys used for information retrieval. Given a transformation algorithm and data to be transformed, certain qualities of the algorithm relating to retrieval problems can be characterized. This paper gives some measures of effectiveness of such transformation algorithms. (11 references)…

Describes a system devised for recording and analyzing the sociologically relevant literature on forest recreation. (JB)

Presents a set of general guidelines for computer literature searches specifically geared to the needs of art education researchers. Two basic modes of accessing information from databases are discussed and the use of Boolian logical operators in structuring searches is explained. (Author/AM)

Describes and discusses the relational organization of a bibliographical database, the notion of normal forms, relational languages, and the advantages of the relational approach to information retrieval. Twenty references are cited. (FM)

Presents an interpolation theorem for an extended Boolean information retrieval model. Results show that whenever two or more documents are similarly ranked at any two points for a query containing exactly two terms, then they are similarly ranked at all points in between; and that results can fail for queries with more than two terms. (Author/LRW)

Explains why Internet groups are a good medium for retrieving and exchanging information. An example of the use of netgroups to obtain information on the Gulf War of 1990-91 is given; the benefits of the informal nature of netgroups are discussed; and a mediated discussion group, Humanist, is described. (LRW)

Discusses the maximum entropy principle (MEP) and applies it to the design of probabilistic retrieval systems. Inconsistent expert judgments and the resulting optimization problem are examined, a linear programing problem is presented that checks the consistency of the expert judgments, and four schemes are proposed to find revised judgments.
