Entity linking method and equipment

The embodiment of the invention provides an entity linking method and device, and the method comprises the steps: employing a vectorization method matched with a target language of a to-be-processed text, and carrying out the vectorization of the entity meaning description of the to-be-processed text and a candidate entity, and obtaining a text vector matrix and a candidate entity vector matrix; fusing the text vector matrix with the candidate entity vector matrix to obtain a first vector matrix; determining association information associated with the candidate entity from a pre-established knowledge graph, and determining an association feature vector according to an association relationship between the association information and the to-be-processed text; the knowledge graph is constructed based on a multi-source heterogeneous entity library; fusing the first vector matrix with the associated feature vector to obtain a second vector matrix corresponding to the candidate entity; and determining a link entity
