Abstract

The application relates to an entity recognition method and device, computer equipment, a storage medium and a computer program product, and relates to the technical field of artificial intelligence. The method comprises the following steps: obtaining a speech recognition result obtained by recognizing target speech; calculating the similarity between an ambiguous entity and each candidate entity in a graph according to the acoustic characteristics of the ambiguous entity in the speech recognition result, to obtain a first similarity score of each candidate entity in the graph; determining a to-be-confirmed set from the multiple candidate entities according to the first similarity score; verifying each candidate entity in the to-be-confirmed set according to a plurality of templates configured in advance; the templates are constructed according to at least two combinations of entity types, entity attributes and relationships in the graph; and determining a target entity from the candidate entities according to the first similarity score corresponding to the candidate entity that passes the verification, to correct the ambiguous entity. The method can improve the accuracy of speech recognition.
