Jardine, N.; van Rijsbergen, C. J. – Information Storage and Retrieval, 1971
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)

Yu, Clement T. – Information Storage and Retrieval, 1974
Heuristic methods for the construction of term classes are presented and experimental results are obtained to illustrate the usefulness of the method. (Author/PF)

Gerson, Gordon M. – Information Storage and Retrieval, 1972
Patents are clustered by similar cited-by" patterns using MacQueen's algorithm. The clusters are enriched by the addition of citing patents. These maximally connected clusters, or cliques, form the classification. (27 references) (Author)

van Rijsbergen, C. J. – Information Storage and Retrieval, 1974
Reports the results of experiments in document clustering using three well-known test collections. (Author)

Rettenmayer, John W. – Information Storage and Retrieval, 1972
This study proposes and investigates file ordering and retrieval techniques which, it is hypothesized, will: (a) reduce the average cost of retrieving records which satisfy a query, and (b) increase the rate of retrieval in the initial portion of the response period. (8 references) (Author)
