Term Extraction Using Co-occurrence in Abstract and First Claim for Patent Analysis
Patent information analysis need to extract patent terms from a vast amount of patent records rapidly and accurately.This paper proposes a patent term extraction method using co-occurrence in abstract and first claim sections of patent records.The research is carried out in three steps.In experiment 1,our proposed method’s F1 is 34.8%and higher than that of KEA with 21.0%.This demonstrates the good performance of our proposed method from a standard point of view.In experiment 2,our proposed method selects only 10,866 qualified terms from 28,044 candidate strings,with the selection percentage of 38.75%.There are 96.8%of total patent claims that contain the candidate terms at the same time.This illustrates the advantage of the proposed method in both eliminating unqualified candidates and providing a good coverage of patent texts from an actual application perspective.
