Abstract: The present disclosure provides a method and apparatus for update processing of a question answering system, relates to the technical field of artificial intelligence and specifically to big data and natural language processing technologies. A specific implementation solution is: acquiring an updated question-answer set; comparing blocks of the updated question-answer set with blocks of an original question-answer set in terms of question-answer pairs to determine an unchanged block and a changed block; acquiring feature data of questions included in the changed block, and creating an index file corresponding to the block, and adding the feature data to an updated training output set; and retaining the index file and feature data corresponding to the unchanged block, and adding the feature data to the updated training output set. The present disclosure can reduce the time consumed in the updating process and occupation of resources.
