Problems solved by technology

[0004] Purpose of the invention: In view of the problems and deficiencies in the prior art, the present invention proposes a method and device for constructing a knowledge map based on UCL semantic indexing, which can standardize and fine-grained index the Internet information, so that the knowledge map represented The semantic information is richer, and at the same time, it can improve the traditional relational reasoning algorithm. When dealing with "one-to-many" and "many-to-one" types of relationships, if the entities on both sides of the relationship are replaced and interfered with, the reasoning performance is unbalanced.

Embodiment Construction

[0029] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0030] The Uniform Content Label (UCL) defined by the national standard "Uniform Content Label Format Specification" (GB / T 35304-2017) is a kind of content metadata that can index the rich semantics of content resources. It can standardize the indexing of content in the media, the Internet and related industries. UCL has the characteristics of flexible structure, simplicity and high efficiency, and can be freely expanded and tailored according to specific application requirements. The invention p...

Abstract

The invention discloses a knowledge graph construction method and device based on UCL semantic indexing. The method comprises the following steps: firstly, extracting entities and relationships from an open link database, and constructing a basic entity library; then crawling news information in each portal website by utilizing a crawler, cleaning and analyzing the news information to form a UCL entity, completing entity disambiguation, and carrying out semantic fusion on the UCL entity and the basic entity library to construct a knowledge graph; and finally, completing the automatic completion of the knowledge graph by utilizing an improved relation reasoning algorithm, so that the automation level of the knowledge graph is improved. According to the method, standardized and fine-grainedsemantic indexing can be carried out on the internet information by utilizing the UCL national standard, so that semantic information expressed by the knowledge graph is richer, and knowledge graph support based on UCL semantic indexing is provided for content big data application based on semantic deep processing.

Description

technical field [0001] The invention relates to a method and device for constructing a knowledge map based on UCL semantic indexing, and belongs to the technical field of the Internet. Background technique [0002] With the rapid popularization of the Internet and the explosive growth of digital information, on the one hand, it has brought valuable information wealth, and on the other hand, how to retrieve effective information from these huge data is also a big challenge for search engines. Traditional search engines mainly feed back relevant webpage links to users by matching the keywords in user search requests by indexing the content in webpages, and sort the results by using webpage sorting algorithms. This model brings great convenience to Internet information retrieval, but the returned results are too single, and users must click on the web page link to do a secondary search to obtain the required information. Internet users hope to obtain accurate, direct and rich ...
