Evaluation of four clustering methods used in text mining

Résumé

Classification systems are used more and more often in artificial intelligence, especially to analyze texts and to extract knowledge they contain. The results of general clustering methods, though, are viewed too often being an absolute reference for classifying terms. This paper's goal is to evaluate quantitatively the quality of classification. Various tools are compared with relation to the same reference medical corpus. We analyze various methods such as hierarchical clustering, neural network, partitioning, co-word analysis which occur in different software systems. The evaluation method used is based on the comparison between a conceptual classfication taken as a reference, and the resulting classifications. This reference classification was realized with the help of a medical expert. It is an handmade classification according the real-world.
