Entity linking method and equipment

The embodiment of the invention provides an entity linking method and equipment, and the method comprises the steps: determining key information of at least one of a to-be-processed text and an entity semantic text of a candidate entity, and enabling the to-be-processed text and the entity semantic text to form a sentence pair; determining a label corresponding to the key information; according to the tag, generating sentence pair key information tag representation; and inputting the sentence pair key information label representation into an entity link model, and predicting a chain index relationship between the candidate entity and the to-be-processed text by the entity link model according to the sentence pair key information label representation. According to the method, the key information label is used for representing the auxiliary information of the chain index relationship between the candidate entity and the to-be-processed text predicted by the entity link model, so that the entity link model can c
