Abstract

Pre-trained language models have achieved good results in the task of sentiment text generation, but existing sentiment text generation methods mostly use soft constraints to control the sentiment attributes of the text as a whole and lack hard control at the word and phrase level. To solve the above problems, this paper proposed sentiment text generation methods under hard constraints. Firstly, it extracted aspect and sentiment words of the sentence and judged sentiment polarity using aspect sentiment analysis techniques. After that, it selected the aspect and sentiment words of the target sentiment as hard-constrained inputs to the pre-trained language model to reconstruct the complete sentence, in which designed a new word weight calculation method, aiming to make the model generate important words in priority. The experimental results show that the sentences generated by this method not only have aspect-level sentiment, but also have significant improvement in the evaluation indexes of text quality and diversity.
