Problems solved by technology

Although this method can achieve better results in some fields, it is more dependent on knowledge triplet templates. They cannot extract better knowledge triplets for common texts, and the knowledge graph constructed also has certain limitations.
[0004] At present, there is no team in China to go deep into the knowledge map of the automotive field, but the knowledge map of the automotive field is very meaningful, whether it is for sellers, buyers, or netizens who want to check car-related information and comments.

Abstract

The invention discloses a construction method and system for an automobile field knowledge graph. The method comprises the following steps: collecting a large amount of automobile field related data in the Internet; classifying the related data according to a preset classification algorithm; carrying out analogy resolution processing on the text of the related data after classification processing; extracting triple data according to a dependency analysis method; and performing visualization processing on the triple data, and constructing an automobile field knowledge map. According to the knowledge graph of the automobile field constructed by the method, the data visualization degree is high, a user can conveniently inquire related information of an automobile, the method is simpler and more convenient, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of knowledge graphs, in particular to a method and system for constructing knowledge graphs in the automotive field. Background technique [0002] Since entering the 21st century, people have gradually realized the importance of information and data. According to the data given by the China Internet Network Information Center, as of the end of 2017, the number of Internet users in my country reached an astonishing 772 million. The number of websites exceeds 5.33 million and is still growing at an annual growth rate of 10.6%. Faced with such a huge amount of data, how people can quickly and accurately obtain the information they want is the problem facing the Internet in China. Google proposed the concept of knowledge graph in 2012. After seeing the advantages and potential of knowledge graph, many researchers have invested in the research of knowledge graph. The knowledge graph can mine the relationship b...
