Relation Converging Of Collective Structure Faced To Discourse And Its Application On Requirement Analysis Of Products

This paper designs and realizes relation converging of collective structure faced to context, and applies it in the electronical product design process. Based on the Domain Chinese Laguage Understanding System, it accomplish the transition from the user's requirement expressed by natural language to the designing requirement of the concept design or design parameter, to supply the sustain for next design.The method based on knowledge should be adopted in the Natural Language Understanding in the field of electronic product design. Based on the Knowledge Base, conceptual dependency theory is chosen as the main analytic method with which relation of collective structure is analyzed. Based on the work done, the processing flowchart of relation converging of collective structure is given, which can understand the sentence with the words that represent a group.Finally, the relation converging of collective structure faced to context is applied to anlysing and understanding of the user's needs of the electronical product design. Tested and debugged together with other parts of the system, the model is satisfactory.
