Abstract


In response to the demand for sentiment analysis in modern cultural studies, the article conducts in depth research on the word vector generation and training methods in Natural Language Processing (NLP). By adopting the hierarchical Sotfmax structure, the problem of matrix sparseness caused by the increase of the vector dimension in word vector description is alleviated. The CNN⁃Softmax model mentioned in the article has a significant improvement in performance due to the introduction of a deeper convolution structure. Accuracy and  have reached 83.8% and 81.9%，respectively, which is about 4% higher than the traditional binary tree⁃ based model.
