The invention discloses a question-answering method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a natural query statement input by a user, andconverting the natural query statement into a semantic symbol string; generating a semantic path corresponding to the natural query statement according to the natural query statement and the semanticsymbol string; according to the semantic path, generating a machine query statement which can be recognized by a database for storing the knowledge graph; and according to the machine query statement,querying a question and answer result corresponding to the machine query statement in a database storing the knowledge graph, and feeding back the question and answer result. According to the method,question and answer templates do not need to be constructed for different knowledge graphs, and compared with an existing question and answer system, the method has better universality, and is high in efficiency and accuracy.
Description
technical field [0001] The invention relates to the technical field of information search, in particular to a question answering method, a question answering device, electronic equipment, and a storage medium. Background technique [0002] The emergence and popularization of the Internet has brought a large amount of information to users, which has met the needs of users for information in the information age. Sometimes you can't get the part of information that is really useful to you, and the efficiency of using information is reduced. This is the so-called information overload problem. At present, using the question answering system to accurately obtain the information required by users has become an important way to obtain information. [0003] Existing question answering systems are mainly completed through search technology, which searches the question sentences on the webpage and then returns the webpage with the highest matching degree. The information obtained in ...
