MRC-based company entity disambiguation method combined with knowledge base

The invention discloses an MRC-based company entity disambiguation method combined with a knowledge base. The MRC-based company entity disambiguation method comprises the following steps: obtaining ato-be-disambiguated statement; splicing the statement to be disambiguated with a questioning sentence to obtain an MRC structure; obtaining different entity description statements corresponding to ambiguous abbreviations in the statement to be disambiguated from an entity knowledge base; splicing different entity description statements at the end of the MRC structure; inputting the MRC structure spliced with the different entity description statements into a Bert model; and enabling the Bert model to output a real entity corresponding to the ambiguous abbreviation to realize statement disambiguation. According to the invention, the accuracy of model prediction is effectively improved, and meanwhile, the generalization ability of the model is supervised, so that the requirements on re-annotation and model training
