This paper proposes a patent retrieval method that consists of two processing stages. In Stage 1, analysis and retrieval methods to improve recall are applied. In Stage 2, the top N documents retrieved in Stage 1 are re-arranged by applying analysis and retrieval methods that consider the claim structure to improve precision. This paper gives an overview of this retrieval method and evaluates its performance at the NTCIR4 Patent Retrieval Task. |
