[Abstract]:In order to effectively excavate the rich design knowledge in patent to assist the innovation design of electromechanical product, this paper designs the framework of patent knowledge mining system of electromechanical product based on innovative evaluation, and discusses the expression method and innovative evaluation of patent design knowledge of electromechanical product. And patent knowledge extraction and other key technology implementation strategy. By analyzing the characteristics of patent design knowledge, using gerund phrases in patent literature to extract innovative hierarchical features, and using the principle of cosine similarity, an innovative evaluation algorithm of patent design knowledge based on vector space is designed. Combining with the method of extracting functional knowledge of patent of mechanical and electrical products, the innovative knowledge of patent design is obtained. The prototype system of patent knowledge mining for mechanical and electrical products is developed, and the practicability of the scheme is verified by the innovative design of oil pepper agitator.
