Gnanadesika, R.; Kettenring, J.R., Tsao, S.L.. Weighting and selection of variables for cluster analysis (Lang.: eng). - In: J.Classif. Vol. 12, No. 1. 1995. p.113-136. One of the thorniest aspects of cluster analysis continues to be the weighting and selection of variables. Reports on the performance of 9 methods on 8 leading case simulated and real sets of data. The results demonstrate shortcomings of weighting basedon the standard deviation or range as well as other more complex schemes in the literature. (Authors, abbr.)

The patent claims a document indexing and retrieval system and method which assigns weights to the key words and assigns a relative value to pairs of key words (i.e., defines a relative relation on KxK) based on their frequency of occurrence and co-occurrence in the document data base.
