Abstract: In the application domain of mobile phone 3D animation automatic generation system, resesrches the information extraction method for Chinese text messages. It proposes a method to do the information extraction on Chinese text messages. A domain template definition method based on the limited context-free grammar is defined. After that designs and implements a template base with the corresponding template parser. The template parser uses the left-first deduction algorithm to ensure the efficiency. Experimental results show that this method can expand the extracted range and improve the accuracy of information extraction.
