What Makes an Automatic Keyword Classification Effective?
Jones, K. Sparck; Barber, E. O.
Journal of the American Society for Information Science, 22, 3, 166-175, May-Jun 71
The substitution information contained in automatically obtained keyword classification is most effectively exploited when: (1) strong similarity connectives only are utilized, (2) grouping is confined to non-frequent terms, (3) term groups are used to provide additional and not alternative descriptive items and (4) descriptor collection frequency is taken into account in matching.
