SMS automatic 3D animation generating system is based on sender message content, by information extraction, semantic analysis and a series of steps, eventually generating a 3D animation which matches the content of the text message. Information extraction in the 3D animation generating system is primary and key, the purpose is to provide animated information for follow-up links to 3D animation automatically generating system. This paper introduces the path feature to realize the extraction of the Chinese text message. It mainly uses the LTP-Cloud platform of Harbin Institute of Technology to preprocess the short message. The path is extracted from the processing result and the path of feature is obtained. Getting rules by combinating the path of features by the first-order inductive learner, and then predicting the relation of messages by matching rules. Finally, Extracting the type of relationship and relation combination in the text message.
