Abstract: The present disclosure includes a method for constructing an intelligent knowledge base. The method comprises: obtaining, via an intelligent-knowledge-base constructing device, a plurality of abstract semantic expressions, wherein each of the plurality of abstract semantic expressions comprises a semantic-lacking element; receiving an initial request message from a user; acquiring, via the intelligent-knowledge-base constructing device, one or more abstract semantic expressions corresponding to the initial request message by performing an abstract semantic recommending process on the initial request message based on the plurality of abstract semantic expressions; extracting, from the initial request message, an element corresponding to the semantic-lacking element of the one or more abstract semantic expressions; filling the extracted element into the semantic-lacking element to obtain one or more specific semantic expressions corresponding to the initial request message; and storing the initial request message and the one or more specific semantic expressions into the intelligent knowledge base.

Abstract: The present invention provides a multi-round questioning and answering method, a method for generating a multi-round questioning and answering system and a method for modifying a multi-round questioning and answering system. The multi-round questioning and answering method includes: acquisition initial request information, and matching the initial request information with a knowledge point in a knowledge base; if it is determined that the initial request information matches with a thematic question in a thematic knowledge point, triggering a root node of a multi-round questioning and answering flow module corresponding to the thematic knowledge point; and, performing, according to a first interaction node to which the multi-round questioning and answering flow module is proceeded currently, one or more knowledge points corresponding to the first interaction node stored in the knowledge base and user interaction information input by an interactive user, questioning and answering interaction with the interactive user.
