The invention discloses an intellectual property unstructured semantic intelligent processing system. The system comprises a server, an intellectual property database, a retrieval function module, ananalysis function module, a data statistics module, an input module and a central processing unit are arranged in the server; a high-frequency vocabulary list, an industry sub-classification list, a question vocabulary list, a statement recognition list,a word library updating module are arranged in the intellectual property database; the high-frequency vocabulary list, the industry sub-classification list, the question vocabulary list and the statement recognition list are all connected with the retrieval function module and the analysis function module through the central processing unit, and the intellectual property database, the retrieval function module, the analysis function module, the data statistics module and the input module are all connected with the central processing unit. According to the intellectual property unstructured semantic intelligent processing system, data retrieval, analysis and statistics in the aspect of intellectual property can be carried out according to the requirements of users, and therefore the retrieval accuracy and the working efficiency of the intellectual property unstructured semantic intelligent processing system are greatly improved.
