¬One approach to classification of users and automatic clustering of documents
Source
Information processing and management. 29(1993) no.2, S.187-195
Year
1993
Abstract
Shows how to automatically construct a classification of users and a clustering of documents on the basis of users' information needs by creating clusters of documents and cross-references among clusters using users' search requests. Examines feedback in the construction of this classification and clustering so that the classification can be changed over time to reflect the changing needs of the users
