In this article, we propose a document clustering method with Natural Language Processing and Self-Organizing Maps (SOM) on our Web based DBMS for clinical cases. The system is implemented in Java language on the Internet server, and all documents of clinical case in the database are written in Japanese. We tested the system ability to evaluate for correct clustering of clinical cases, that each document has 30 attributes in an input-vector for SOM-learning. For the result of this ability test, it shows that 73.3% of clustering datasets are correct answers. Thus, it seems that our method is available to search the similar cases in the database.
