Abstract

The invention discloses a multi-round dialogue method and device in a knowledge question-answering system. The multi-round dialogue method comprises the following steps: acquiring a historical entityand a historical relationship of a current question sentence; screening out candidate entities according to the current questions; performing weighting processing on the features of the candidate entities to obtain a main entity; forming a candidate path according to the adjacent relationship between the main entity and the historical entity in the knowledge base and the adjacent entities; performing weighting processing on the features of the candidate paths to obtain a final path; obtaining an answer according to the final path and returning the answer to the user; and obtaining all entitiesand all relationships of the final path as historical entities and historical relationships of the next round of questions and answers. Through the method, the historical information of the previousquestion sentence is completely added into the current question and answer, so that the historical information acquisition accuracy is ensured, and a large amount of labor cost is avoided.
