Peer reviewedBookstein, A.; Klein, S. T.; Raita, T. – Journal of the American Society for Information Science, 1998
Defines the notion of serial clustering of words in text, and explores the value of such clustering as an indicator of a word's bearing content. This approach is flexible in the sense that it is context-sensitive; a numerical approach may also be of value in assigning weights to terms in requests. Experimental support is obtained from natural text…

Peer reviewedShepherd, Michael A.; Phillips, W. J. – Journal of the American Society for Information Science, 1986
Defines relationship between user profile and user query in terms of relationship between clusters of documents retrieved by each, and explores the expression of cluster similarity and cluster overlap as linear functions of similarity existing between original pairs of profiles and queries, given the desired retrieval threshold. (23 references)…

Peer reviewedShaw, W. M., Jr. – Information Processing and Management, 1993
Describes a study conducted on the cystic fibrosis (CF) database, a subset of MEDLINE, that investigated clustering structure and the effectiveness of cluster-based retrieval as a function of the exhaustivity of the uncontrolled subject descriptions. Results are compared to calculations for controlled descriptions based on Medical Subject Headings…

Peer reviewedSmall, Henry – Journal of the American Society for Information Science, 1986
Applies a method for generating synopses of scientific fields to a co-citation cluster in field of cancer virology and describes the resulting specialty narrative. Implications of procedure for the cognitive processes involved in reviewing a field are discussed. Appended are lists of highly cited and citing papers. (35 references) (EJS)

Peer reviewedYerkey, A. Neil – Journal of the American Society for Information Science, 1983
This study attempts to analyze descriptors taken from subject categories in ERIC thesaurus and used as search terms on CROSS database Bibliographic Retrieval Services. An expectation ratio was computed and cluster analysis was conducted to discover subject relationships among databases. A list of databases retrieved and 12 references are appended.…

Peer reviewedGarland, Kathleen – Information Processing and Management, 1983
Describes method of automatic document classification in which documents classed as QA by Library of Congress classification system were clustered at six thresholds by keyword using single link technique. Automatically generated clusters were compared to Library of Congress subclasses, and partial classified hierarchy was formed. Twelve references…
