KNOWLEDGE GRAPH-BASED ENTITY LINKING METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/073254
Kind Code:
A1
Abstract:
A knowledge graph-based entity linking method and apparatus, a device, and a storage medium. The method comprises: performing word segmentation on a legal text to obtain a word segmentation result; looking up whether there is an entity reference that is the same as the word segmentation result; if yes, placing the entity reference into an entity reference set, and placing an entity into a candidate entity set; separately calculating an association score and related scores, and performing addition on the association score and each corresponding related score to obtain an objective function; and in the entity reference set, determining the entity reference having a maximum objective function value as a final entity reference, and linking the final entity reference to a corresponding entity in a legal knowledge graph. By calculating the association score of the entity reference and the related scores between candidate entities, determining the final entity reference, and linking the entity reference, the present invention avoids the phenomenon that there is a synonym and polysemy in the legal text.
