The invention discloses a question answering method, equipment and a computer-readable storage medium. The method includes the steps of: after receiving a question to be answered, extracting keywords in the question to be answered; Find the corresponding intention vocabulary in the search, and determine the target intention corresponding to the question to be answered according to the intention vocabulary; determine the predicate candidate set in the preset knowledge graph according to the subject entity word and target intention in the question to be answered, and determine the predicate keyword in the keyword ; If the target predicate corresponding to the predicate keyword is found in the predicate candidate set according to the preset algorithm, the answer corresponding to the question to be answered is determined according to the target predicate, and the answer is output. In the process of using the knowledge graph to answer questions, the present invention analyzes the intention of the user's question to answer the user's reason-type or explanation-type questions, thereby improving the accuracy of question answering.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a question answering method, device and computer-readable storage medium. Background technique [0002] The existing knowledge map is to match the questions through triples and get the corresponding answers. Each triplet represents a statement of fact, such as triplets can be (little A, nationality, China), (little A, nationality, Han nationality) and (little A, constellation, Virgo). When the question is "What is Little A's constellation", the system where the knowledge graph is located will first recognize the named entity word "Little A" in the question, then recognize the predicate "constellation", and then compare "Little A" and "constellation" To match the triplet in the knowledge map, so that the matched triplet is (little A, constellation, Virgo), and the corresponding answer is "Virgo". It can be seen from this that the existing knowledge graph can only answe...
