Integrating Content and Citation Information for the NTCIR-6 Patent Retrieval Task

چکیده
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 application 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 accuracy for the English Retrieval Subtask.

متن کاملOverview of Classification Subtask at NTCIR-6 Patent Retrieval Task
This paper describes the Classification Subtask of the NTCIR-5 Patent Retrieval Task. The purpose of this subtask is to evaluate the methods of classifying patents into multi-dimensional classification structures called F-term (File Forming Term) classification systems. We report on how this subtask was designed, the test collection released, and the results of the evaluation.
