Embodiments of the present invention provide an entity linking method, apparatus, electronic device, and storage medium, wherein the method includes: inputting several linked entities in the context text to which the entity reference to be linked belongs, and several candidate entities for the entity reference To the entity link model, obtain the candidate link result output by the entity link model; wherein, the entity link model is used to determine the linked entity attention feature corresponding to each candidate entity based on each linked entity, and based on each candidate entity Entity linking is performed on the corresponding linked entity attention features respectively; based on the candidate linking results, the entity linking results referred to by the entities are determined. The entity linking method, device, electronic device and storage medium provided by the embodiments of the present invention eliminate the interference of irrelevant linked entities and improve the accuracy of entity linking.
Description
technical field [0001] The present invention relates to the technical field of natural language processing, in particular to an entity linking method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of the Internet, the Internet is flooded with various types of text information, including various entity designations such as names of people, places, and organizations. Due to the diversity of natural language expressions, an entity reference can often point to multiple real entities. Therefore, in order to correctly understand the real meaning of the entity reference in the text, it is necessary to link the entity reference in the text to the corresponding unambiguous entity knowledge base. Physically. [0003] At present, entity linking methods mainly include the following methods: select the candidate entity with the highest popularity as the linking result; or, realize the linking of all entity references based on t...
