| Abstract(in English) | Due to explosive increase of the number of web pages, the number of copyright violation web pages, such as lyrics or news citation pages without permission, has also been increased. To solve this problem, we propose a system for detecting copyright violation web pages. The proposed system consists of three steps. Firstly, the system generates search keywords on phrasal units, called "bunsetsu", which are included in the "seed page." Secondly, on search keywords generated by the first step, the system gathers candidate of web pages violating copyright by using Google or Yahoo! web service. Finally, the system re-ranks the candidate web pages with similarity to the seed page. Here, we adopted "Longest Common Subsequence" of phrasal units, as a similarity measurement. Our evaluation confirmed that proposed system is able to extract copy violation web pages correctly. |
