Abstract

The invention provides a word classification model training method and device based on artificial intelligence, a word processing method and device, electronic equipment and a storage medium. The method comprises the steps: obtaining a seed entity word set composed of a plurality of seed entity words, wherein the plurality of seed entity words belong to a to-be-mined entity type; combining any twoseed entity words in the seed entity word set to obtain a positive example sample pair; obtaining a historical text including the seed entity words, and constructing a negative example sample pair according to the seed entity words and the historical text excluding the seed entity words; updating a word classification model through the positive example sample pair and the negative example samplepair, wherein the updated word classification model is used for determining the probability that the entity words to be recognized belong to the entity types to be mined. Through the method and the device, the richness of model training samples can be improved, the corpus annotation cost required by entity mining is reduced, and meanwhile, the training effect of the word classification model can also be improved.

Description

technical field [0001] The present invention relates to artificial intelligence technology, in particular to an artificial intelligence-based word classification model training method, word processing method, device, electronic equipment and storage medium. Background technique [0002] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. Natural Language Processing (NLP, Nature Language Processing) is an important direction of artificial intelligence. It mainly studies various theories and methods that can realize effective communication between humans and computers using natural language. [0003] Entity word classification is an important application of natural language processing. By determining the entity type of entity words in t...
