This paper describes our system participated in the Japanese and English Retrieval Subtasks at the NTCIR-6 Patent Retrieval Task. The purpose of these subtasks is the invalidity search, in which a patent ap- plication including a target claim is used to search documents that can invalidate the demand in the claim. Although we use a regular text-based retrieval method for the Japanese Retrieval Subtask, we combine text and citation information to improve the retrieval ac- curacy for the English Retrieval Subtask. |
