| Abstract(in English) | To achieve easy search and reuse of business documents stored in a file server, we propose a new clustering method to generate virtual folders which are implemented as search criteria. Our method has two features ; 1) it extracts keywords from metadata, 2) it generates hierarchical clusters of appropriate size using metadata frequency difference. The experimental result demonstrates that our method achieved 97% precision and 86% recall. Moreover, it was able to extract unexpected keywords. |
