Abstract

A statistics-based approach for clustering documentsand for extracting cluster topics is described. Relevant(meaningful} Expressions (RES} automatically extractedfrom corpora are used as clustering base features. Thesefeatures are transformed and its number is strongly reducedin order to obtain a small set of document classijication features. This is achieved on the basis of Principal Components Analysis. Model-Based Clustering Analysis finds thebest number of clusters. Then, the most important RES areextracted from each cluster and taken as document clustertopics.
