Embodiments of the present invention disclose a list-type knowledge Q&A library construction method, an answering method, an apparatus and a system. The method comprises: acquiring question information input by a user; acquiring feature information from the question information; according to the question information, determining a knowledge type contained in the question information, wherein the knowledge type comprises list-type knowledge and other types of knowledge; if the question information contains the list-type knowledge, determining whether the feature information exists in a list-type knowledge table associated with the question information; if yes, calling a Q&A model corresponding to the question information to generate a positive answer; and if no, calling the Q&A model corresponding to the question information to generate a negative answer. The situation that other types of answers are given for the list-type knowledge is avoided, so that answers are generated in a correct Q&A form when answering the question that contains the list-type 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?"
