| Abstract: | Patent information retrieval is a major means to access the patent information,it plays an important role in the patent application.Base on the analysis of current technologies involved in patent information retrieval,we propose a patent information retrieval approach on the concept.First,we analyze the concept content of patent documents,and according to this,use different feature selection method.Then,the key issues of the concept-based patent information retrieval method including query expansion and patent similarity calculation are also described. |
