| Abstract: | Purpose/significance] Patent similarity detection assists the formulation of the national innovation strategy planning macroscopically, finds hotspots in China and all over the world, and deals with patent rogues in other countries. Microscopically, patent similarity detection provides support for patent inventors, patent examiners and patentees.Method/process] A new method was proposed based on deep learning of Doc2Vec model, with patent corpus based on no data clearance of domain knowledge. Then typical patents were randomly selected to carry on similarity detection by this new method, and the results with traditional similarity detection models were compared.Result/conclusion] According to experimental results, the new deep learning of Doc2Vec method and TFIDF model has similary results which both of the model's patent corpus all based on no data clearance of domain knowledge.The new method requires less professional skill in specific domain knowledge, and didn't require the process of data clearance. It can givesa new intelligent support tool for patent infringement and patent investigation, reduce the research threshold and workload, and improve service efficiency. |
