| Abstract(in English) | This paper investigates the performance of two criterion functions and four different algorithms for document clustering. The criteria, that we evaluate, are the cosine similarity criterion and the entropy-based criterion. The quality of a clustering solution is evaluated how the various classes of documents are distributed within each cluster. We present an experimental evaluation involving all combination of criterion functions and algorithms. Our experimental results show that the entropy-based criterion is superior to the cosine similarity's and that competitive learning algorithm with the entropy-based criterion achieves the best performance. |
