Abstract

The invention discloses a method and a device for constructing a patent data knowledge map. The method comprises the following steps: obtaining patent data of an existing patent database, preprocessing the patent data to unify a patent data format, and segmenting the patent data after being merged with the same type to obtain the segmentation data of each type of patent data; performing knowledgeextraction of preprocessed patent data, performing data cleaning of word segmentation data of each type of patent data to obtain the corresponding subject original file, extracting keywords to obtainsubject words, and constructing a patent subject database for each type of patent data; defining the entity of patent data, determining the subject of patent data, identifying the entity and subject of patent according to the general knowledge map, mining the semantic relationship between the entity and the subject, and constructing the patent data knowledge map.

Description

technical field [0001] The invention belongs to the technical field of patent data analysis and processing, and in particular relates to a method and device for constructing a knowledge map of patent data. Background technique [0002] With the development of the times, innovation has become more and more important at all levels of society, such as enterprise production and development, and scholars' scientific research. Patent data contains almost all solutions for innovation, invention and technical problem solving in all walks of life. Compared with other information resources, patent data has comprehensive information, detailed content, standardized format, scientific classification, time stamp and value. characteristic. Nowadays, patents are valued by more and more companies such as Huawei and Tencent. They will pay attention to and analyze newly released patents by universities and other institutions and individuals, and buy out valuable patents at a lower price in ad...
