Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific examples.

[0026] To integrate business structured data and Wikidata data, first, it is necessary to build an entity alignment method to link entities in business data and Wikidata data entities; second, build a data model that covers both business data and Wikidata data.

[0027] At present, the entity alignment method is mainly used in the fusion of business knowledge bases, such as the entity alignment of two knowledge graphs. The strategies used include grouping, knowledge representation, similarity calculation, etc., which cannot be fully applied to Wikidata data fusion. In addition, after entity fusion, an appropriate ontology data model needs to be constructed in order to store business data and Wikidata data. At present, relevant research is relatively lacking, and Wikidata is often stored separately, which does not realize the true integration of Wikidata data and business data,...

Abstract

The invention discloses a Wikidata fused entity alignment method, which belongs to the technical field of natural language processing, and comprises the following steps of: carrying out grouping according to label information and specific service data in Wikidata through data preprocessing, specifically obtaining each group, constructing a matching pair for each entity in the service data and each entity in Wikidata, establishing a matching pair for each entity in the service data and each entity in the Wikidata, and selecting the matching entity pair by calculating the similarity. According to the method, data fusion and retrieval requirements can be supported, real fusion of Wikidata data and service data is realized, and the retrieval efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to an entity alignment method integrated with Wikidata. Background technique [0002] In knowledge-intensive business fields such as medical care and education, it is often necessary to build a search query system based on Internet content. One of the solutions is to integrate business structured data with Wikidata and other encyclopedia data to establish a system for structured data and Wikidata data. Association relationship, realize the coverage of Wikidata data, and support the needs of subsequent retrieval and analysis. However, the methods currently used cannot realize the real integration of Wikidata data and business data very well, which limits the retrieval efficiency during application. Contents of the invention [0003] The technical task of the present invention is to provide a Wikidata-integrated entity alignment method for the above deficiencies...
