Experiments with Syntactic Traces in Information Retrieval
De Heer, T. – Information Storage and Retrieval, 1974
Use of syntactic trace as an access strategy for large files containing arbitrary languages for which thesaurus-based and multiple attribute search techniques are unsuitable. (LS)
Descriptors: Indexing, Information Retrieval, Information Storage, Mathematical Models
An Evaluation of Query Expansion by the Addition of Clustered Terms for a Document Retrieval System
Minker, Jack; And Others – Information Storage and Retrieval, 1972
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)
Descriptors: Automatic Indexing, Cluster Analysis, Data Processing, Information Retrieval
A Model of Information Retrieval Process for Hierarchical Set of Descriptors
Laus, Krystyna; Dabrowski, Miroslaw – Information Storage and Retrieval, 1974
Presents a model information retrieval system for the case when a hierarchic set of descriptors is defined. (Author/PF)
Descriptors: Information Retrieval, Information Storage, Models, Subject Index Terms
Term Association Analysis on a Large File of Bibliographic Data Using a Highly-Controlled Indexing Vocabulary
Jacquesson, Alain; Schieber, William D. – Information Storage and Retrieval, 1973
An experiment to compute and analyze the degree of association between descriptors used to index a document collection of approximately 40,000 records is described. An analysis of the results is presented which indicates the difficulties inherent in applying the results to an operating system. (11 references) (Author)

Comment on "An Evaluation of Query Expansion by the Addition of Clustered Terms for a Document Retrieval System"
Salton, G. – Information Storage and Retrieval, 1972
The author emphasized that one cannot conclude from the experiments reported upon that term clusters (or equivalently, keyword classifications or thesauruses) are not useful in retrieval. (2 references) (Author)
