Abstract In order to get similar patents from patent databases, based on merging similar concepts on Ontology-based identification replacement, this paper constructs a vector space model by estimating the TFIDF values of the concepts, and eventually gets a collection of similar clause on similarity matching sentences by orderly longest common subsequence identification method to match the results of previous similar patent document extraction. This method can help enterprises intelligence detect similar patents effectively.
