  • This paper mainly studies how to extract the common structure and process methods of expectation from scene-specified expectation setting, then puts forbh the algo-rithms to build expectation model suitable for dialogue systems based on the task model. When incorporated with dialog context, this model could create dynamic situation that varies with, dialogue process, which endows the system with the preliminary ability to reason users intentions by reference to this situation, so as to improve the robustness and precision of semantic analysis and the dialogue success rate. Finally, the experimental results prove the effectiveness and usability of this model.
