POSTECH at NTCIR-6 English Patent Retrieval Subtask
نویسندگان
چکیده
This paper reports our experimental results at the NTCIR-6 English Patent Retrieval Subtask. Our previous participation at the patent retrieval Subtask revealed that the long length of the patent applications require less smoothing of the document model than general documents such as news paper articles. We setup the initial baseline retrieval system for U.S. patent applications and compare the difference from that of Japanese patent applications.

Overview of the Patent Retrieval Task at the NTCIR-6 Workshop
In the Sixth NTCIR Workshop, we organized the Patent Retrieval Task and performed three subtasks; Japanese Retrieval, English Retrieval, and Classification. This paper describes the Japanese Retrieval Subtask and English Retrieval Subtask, both of which were intended for patent-to-patent invalidity search task. We report the evaluation results of the groups participating in those subtasks.

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 Su...

This report describes the experimental results of our participation at the Document Retrieval Subtask of NTCIR-5 Patent Retrieval Task. Unlike newspaper articles which belong to the main document type handled in previous information retrieval experiments, patent documents have many different characteristics in terms of length, technicality, structureness, etc. Among these, we focus on the lengt...
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.
