The present disclosure discloses a method and a device for locating an answer based on question and answer, in which the method includes: receiving a query sentence; parsing the query sentence, to generate a semantic parse tree corresponding to the query sentence; matching the semantic parse tree with a pre-established matching base, to obtain an alignment probability between each of candidate answers in the pre-established matching base and the semantic parse tree; and determining a final answer according to the alignment probability.

Method and device for locating an answer based on question and answer

Embodiments of the present invention provide a method, system and storage medium for implementing intelligent question answering. The method includes: receiving a query question; performing a semantic analysis of the question; performing corresponding search processing for the question based on a result of the semantic analysis, wherein the search processing includes search processing performed for the question by at least one of a semantic relationship mining system, a text library search system, a knowledge base search system, and a question and answer library search system; and returning an answer based on a result of the search processing. In this way, the accuracy of answers to the questions is effectively improved.
