| Abstract(in English) | In this paper, we consider a data mining problem for semi-structured data. We present an efficient algorithm for discovering frequent substructures from a given large collection of semi-structured data by modeling semi-structured data as labeled ordered trees. This algorithm is a generalization of the itemset enumeration technique, called set-enumeration tree, by Bayardo(SIGMOD'98)to ordered tree enumeration. The experiments on HTML documents show that the algorithm is efficient and scalabel on realworld data. |
