| Abstract(in English) | We study a novel problem of mining subtrees with frequent occurrence of similar subtrees, and propose an efficient algorithm for this problem. According to our problem setting, frequency of a subtree is counted not only for equivalent subtrees but also for similar subtrees. Our experiment showed that our algorithm is enough fast for practical use. Preliminary experiment for data record extraction using our mining method also showed encouraging result. |
