摘要
In natural language problems, the relationship expression in the knowledge base is diversified. Therefore, matching the answers of the knowledge base question and answer through representation learning is still a challenge. To make up the shortcomings, a knowledge base question answering method incorporating fact text is proposed. Entities, entity types and relationships in the knowledge base are converted into fact text. A pre-trained language model(BERT) is employed for representation. The vector of question and answers in low dimensional semantic space is obtained using the rich semantic mode of BERT. The answer with the closest semantic similarity to the question is matched by calculation. Experiments show that the proposed method is effective and robust in answering common simple questions. © 2021, Science Press. All right reserved.
