Intention recognition method, device and system

The invention provides an intention recognition method, an intention recognition device and an intention recognition system. The method comprises the steps of converting user dialogue information inputted by a user into session vector information, carrying out the semantic recognition of the session vector information through a plurality of semantic recognition models, obtaining a plurality of semantic recognition results, sorting the semantic recognition results by utilizing an intention sorting model in combination with the session preceding text information and the user information, and taking the semantic recognition result with the highest sorting as a final intention recognition result. According to the embodiment of the invention, multiple features such as session context and user information are combined. The method for accurately identifying the user intention in the complex context is provided. The user intention is more accurately identified in a multi-round interaction scene. The intention identif
