Abstract

The invention relates to an artificial intelligence technology, and provides a word vector generation method and device, computer equipment and a storage medium, and the method comprises the steps: training a word in a corpus through a preset model, and obtaining an initialization vector of the word in the corpus; the candidate words of the to-be-constructed word vector words generated based on the initialization vectors of the words are sorted through the preset sorting model to obtain the positive correlation set and the negative correlation set of the to-be-constructed word vector words, and the candidate words are sorted, so that the number of annotations of the words is reduced, the training efficiency of the model is improved, and the training efficiency of the model is improved. The positive correlation set and negative correlation set samples are obtained through the preset sorting model, the quality of the samples is improved, the high-quality samples are sent into the contrast learning model for training, and the generation quality of the word vector of the word vector word to be constructed is improved.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, and in particular, to a method, device, computer equipment and storage medium for generating word vectors. Background technique [0002] Natural language processing is an important direction in the field of computer science and artificial intelligence. At present, natural language processing tasks include machine translation, sentiment analysis, text summarization, text classification and information extraction. In natural language processing tasks, the first step is to consider how to enable computers to represent natural language. Computers cannot directly represent natural language. Therefore, we need to design a method to mathematicalize natural language so that computers can process it. This is word vector. [0003] In the prior art, word vectors are mainly obtained by an active learning method or a comparative learning method. In the active learning method, a large amount of...
