Abstract

The invention provides an entity mention classification method and device, electronic equipment and a storage medium. The artificial intelligence technology is involved; the method comprises the following steps: acquiring a plurality of brother entity mentions corresponding to entity mentions to be classified from an entity mention set; obtaining a second graph neural network based on the to-be-classified entity mentions and the plurality of brother entity mentions; on the basis of the initial feature representation mentioned by the to-be-classified entity and the feature representation mentioned by each brother entity, calling a second graph neural network to carry out first iteration updating processing to obtain the updated feature representation mentioned by the to-be-classified entity; based on the updated feature representation of the to-be-classified entity mention and the feature representation of the plurality of entity mention types, determining the prediction probability of the to-be-classified entity mention on the plurality of entity mention types; and determining the entity mention type of which the prediction probability is greater than a first probability threshold as the entity mention type corresponding to the to-be-classified entity mention. According to the invention, the accuracy of entity mention classification can be improved.

Description

technical field [0001] The present application relates to artificial intelligence technology, and in particular, to a method, apparatus, electronic device and storage medium for entity mention classification. Background technique [0002] Artificial Intelligence (AI) is a comprehensive technology of computer science. By studying the design principles and implementation methods of various intelligent machines, the machines have the functions of perception, reasoning and decision-making. Artificial intelligence technology is a comprehensive discipline that covers a wide range of fields, such as natural language processing technology and machine learning / deep learning. With the development of technology, artificial intelligence technology will be applied in more fields and play a more increasingly important value. [0003] With the rapid development of artificial intelligence, Knowledge Graph (KG) has received extensive attention due to its powerful data description capabiliti...
