At present, the rapid development of NLP technology makes it more and more convenient in the direction of intelligent information retrieval and screening. The semantically based retrieval algorithm can effectively improve the retrieval rate by calculating the similarity between two sentences. This paper proposes a method to obtain the similarity between sentences based on Bert model, and compares the traditional ALBERT, ESIM and BIMPM models. Experimental results show that the accuracy of BERT model in calculating text similarity reaches 87%, which is obviously better than other models. At the same time, the synonym model is trained based on Word2Vec to obtain synonyms related to the target word. Therefore, the algorithm adopted in this paper can effectively improve the retrieval efficiency.
