SOME COMPROMISES BETWEEN WORD GROUPING AND DOCUMENT GROUPING

Abstract

Statistical analysis of the text of document collections has yielded, for information retrieval purposes, two broad classes of output: word grouping and document grouping. Associative indexing comes under the general heading of word grouping and automatic classification is a kind of document grouping. Document grouping and word grouping can be combined to give a scheme of classification with more attractive features than could be achieved with either document grouping or word grouping alone. A hierarchical grouping program written by J. H. Ward of Lackland Air Force Base for use in classifying personnel by skill and aptitude is discussed. This program turns out to be nearly ideal as a basis for a mixed document and word-grouping approach.
