The embodiment of the invention discloses a construction method, answering method, device and system of a list-type knowledge question-answer database. The method of the present invention includes: acquiring question information input by the user; acquiring feature information from the question information; determining the type of knowledge contained in the question information according to the question information; the knowledge type includes: a list type knowledge and other types of knowledge; if the problem information contains list-type knowledge, determine whether the feature information exists in the list-type knowledge table associated with the problem information; if so, call the corresponding A question-and-answer model for generating an affirmative answer; if not, calling a question-and-answer model corresponding to the question information to generate a negative answer. The situation that other forms of answers are given to tabular knowledge is avoided, thereby ensuring that answers are generated in the correct answer form when answering questions containing tabular knowledge.
Description
technical field [0001] The invention relates to the technical field of language information processing, in particular to a method for constructing a list-type knowledge question-answer database, an answer method, a device and a system. Background technique [0002] With the development of Internet technology, people's dependence on the Internet has gradually deepened, such as figure 1 As shown, when people encounter problems, they are used to finding the answers they need on the Internet. For example, people often encounter such questions in life: "Can lighters be brought on the plane?" "Can hairspray be brought on the plane?" "Is alcohol prohibited by plane?"
