Abstract

A method and apparatus for entity link are provided, wherein that method includes: processing a text to obtain at least one participle, wherein at least one participle contains entity reference; Determining a word vector corresponding to each of the at least one participle; Inputting a word vector corresponding to at least one word segmentation into an operation model to calculate a feature vectorof entity reference; Calculating the similarity between the feature vector of entity reference and the feature vector of each candidate entity in the candidate entity set; selecting the candidate entity corresponding to the maximum similarity as the linked entity of entity reference. In this way, the candidate entity matching the entity reference in the text can be selected from the candidate entity set, so that the entity linking accuracy is high.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular, relates to a method and device for entity linking. Background technique [0002] Entity linking refers to the process of identifying entity mentions in text and linking them to corresponding entities in the knowledge graph, which can solve the problem of ambiguity between entities. The key to entity linking is how to select the correct entity from the candidate entity set, which can directly affect the application effect of entity linking in automatic question answering, information retrieval, knowledge graph construction and other fields. For example, in the intelligent answering system, when parsing the text "What is Jordan's highest score in a single game in his career?", it must first be identified that the entity reference "Jordan" actually refers to the "Jordan" in the knowledge graph. Michael Jordan" entity, so that Jordan's highest score in a single game...
