Problems solved by technology

[0003] At present, it is mainly to determine the context sentence of each word to be disambiguated, and to calculate the similarity between each definition of each word to be disambiguated and the context sentence after performing representation learning on the context sentence and the sentence of the meaning of the word to be disambiguated. Degree, select the definition with the highest similarity as the definition of the word to be disambiguated, but this method can only roughly classify the definition of the word to be disambiguated, the accuracy rate is low, and the accuracy of word meaning disambiguation is poor

Abstract

The invention relates to the technical field of natural language processing, and discloses a word sense disambiguation method and device based on context semantics, computer equipment and a storage medium. The method comprises the following steps: acquiring text data, and preprocessing the text data to obtain to-be-processed data; inputting the to-be-processed data into a pre-trained language model for training to obtain previous context information, ambiguous word information and next context information; according to the previous context information, the ambiguous word information and the next context information, obtaining text segment semantic information; inputting the semantic information of the text segment into the pre-trained classifier for training, determining the definition of the ambiguous word information in the current context, so that the accuracy of word sense disambiguation is improved.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a context semantics-based word sense disambiguation method, device, computer equipment and storage medium. Background technique [0002] There are a certain number of ambiguous words in language vocabulary, which bring convenience to the application of natural language, but also bring certain difficulties to the understanding and translation of natural language. With the rise of artificial intelligence, word sense disambiguation has been applied more and more in many high-tech fields, and it has become an important problem that needs to be solved in natural language processing. [0003] At present, it is mainly to determine the context sentence of each word to be disambiguated, and to calculate the similarity between each definition of each word to be disambiguated and the context sentence after performing representation learning on the context sentenc...
