When the corpus is insufficient, the usergenerated answer is generated form Free Talk. In our system, the ASR transcription is processed through Chinese Knowledge and Information Processing (CKIP) Chinese words segmentation system. Then, filtering the command sentences through human machine interface, remaining normal sentences are passed the dialogue system, and normal sentences are vectorized through preprocess bag of word. All sentences of corpus have been preprocessed and vectorized in vector space model, then, input sentence is calculated by sentence similarity with vector space model. In order to make system more enjoyable, we adapt image recognition to record the round emotions. According to the round emotions, to response the emotion conversation.
