Abstract

The invention discloses an entity linking method and system, a storage medium and electronic equipment, and the method comprises the following steps: obtaining a document entity list: carrying out the entity recognition of an online document through an entity recognition model, and obtaining the document entity list; a user name obtaining step: distributing an ID for each login user to obtain an identifier i d, and obtaining a user name list through the identifier i d; an abstract vector acquisition step: acquiring an abstract vector of the online document through a TextRank algorithm according to the online document; and a linking step: obtaining word vectors according to the document entity list and the user name list, obtaining similarity according to the word vectors and the abstract vectors, and carrying out entity linking according to the similarity and a set threshold value. According to the invention, the text abstract, the entity in the graph, the entity attribute and the relevancy of the relationship are utilized, so that the accuracy and recall rate of entity linking are improved.

Description

technical field [0001] The invention belongs to the field of entity linking, and in particular relates to an entity linking method, system, storage medium and electronic equipment. Background technique [0002] With the rise and rapid development of the Internet, cloud technology, and artificial intelligence, text data has experienced explosive growth. Since online documents can support users to edit documents anytime and anywhere, collaborative editing among multiple users, and cloud storage, etc., more and more The more favored by users and enterprises. Correspondingly, more and more online data will be generated. Users and enterprises urgently need efficient and intelligent online text analysis technology to understand the true meaning of data, so as to help users and enterprises quickly obtain useful information. Entity linking technology is a text analysis technology that takes words or phrases appearing in text data as entities and associates them with corresponding e...
