Abstract

The invention relates to the technical field of artificial intelligence, and discloses an entity identification method, device and equipment and a storage medium, which are used for improving the accuracy and identification efficiency of entity identification. The method comprises the steps: receiving a to-be-identified statement of a target domain input by a user; performing word segmentation processing on the to-be-recognized statement to obtain corresponding word blocks, and performing vectorization processing to obtain text word vectors; respectively inputting the text word vectors into apreset deep learning model, a preset statistical model and a preset dictionary model or performing entity prediction by using a preset regular expression to respectively obtain corresponding entity recognition result sets; combining the obtained corresponding entity identification result sets; judging whether one entity corresponds to a plurality of recognition results in the entity recognition result set obtained by merging, and performing corresponding processing according to a judgment result to obtain a target entity recognition result set corresponding to each field in the to-be-recognized statement.

Description

technical field [0001] The present invention relates to the technical field of semantic analysis of artificial intelligence, in particular to an entity recognition method, device, equipment and storage medium. Background technique [0002] At present, named entity recognition in the field of natural language processing mainly uses a single entity recognition model to perform entity recognition on each entity one by one. The single entity recognition model has low recognition accuracy and low recognition efficiency, and cannot recognize different types of entities; in addition, for the target field, For example, in the insurance field, there is no specific entity recognition algorithm yet. Contents of the invention [0003] The main purpose of the present invention is to solve the technical problem of low recognition accuracy and low efficiency due to a single entity recognition model. [0004] In order to achieve the above object, the first aspect of the present invention...
