| This paper makes a preliminary discussion on the Chinese natural language understanding of the product design. During it, the keystone is processing of collective structure which is expressed as a group. By understanding and analyzing the phrase in user requirements which is expressed in natural language style and converting them into the requirements of conceptual design with the whole system running, the subsequent design is supported.The method based on knowledge should be adopted in the natural language understanding in the field of mechanical product design. Based on the Knowledge Base, Ontology theory is chosen as the main analytic method with which collective structure is analyzed deeply. At the same time, the group relation is classification and presentation. Based on the work done, the processing flowchart of collective structure is given, which can understand the sentence with the words that represent a group. Finally, partial discourse analysis of natural language understanding is applied to mechanical automation. With other models running, the system runs well. |
