Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: A method, system and computer device for interacting in a multi-round session are disclosed. The method comprises: receiving user requirement information (101); mapping the user requirement information to standard requirements contained in nodes of a plurality of locally preset requirement structure trees, the standard requirement contained in each node being a general requirement of standard requirements contained in sub-nodes of the node in the requirement structure trees (102); and outputting content of the standard requirements contained in sub-nodes of a selected non-leaf node or session information corresponding to a selected leaf node, if the standard requirement contained in the selected node in the plurality of requirement structure trees matches the user requirement information (103). The above technical solution provides a session interaction method for a task-based session system with a tree-like hierarchical dependency, while improving the matching rate of the user requirement.
