Hiroki Tanioka, Kenichi Yamamoto · 2005
We developed a distributed search system with the corresponding very large scale corpora from NTCIR-5 Patent Retrieval Task. And we developed the method of query refining using Support Vector Machines. Our search system, which consists of 5 PCs could make indices of all claims for ten years. Additionally, we confirmed that our arranging the scoring method made an improvement of mean average precision.
