The Application Of Word Intelligent Segmentation And Clustering Of Domain Chinese Understanding In The Design Of Machinery Product

This text designed and realized the intelligent words segmentation and the Clustering analysis module,then applied these in the mechanical product design process. Based on the Domain Chinese Understanding System ,it accomplished the transform from the user's requirement expressed in the form of natural language into the designing requirement of the Concept Design or design parameter.First of all, this text analyzed the pluses and minuses of existing words Segmentation methods, put forward a new kind of intelligent words segmentation module, which incorporated the Automatic segmentation theory and the semantic segmentation theory and based on the System theory. In this system, the intelligent words segmentation module was embedded into the Domain Chinese Understanding system as an important module. It produced all possible words segmentation result in the Automatic Words segmentation stage, and excluded the improper result of words segmentation with lexical analysis. Then excluded the rest improper result of words segmentation with semantic analysis in the followed Domain Chinese Understanding system modules,at last, it utilized the feeding-back module to fed the result produced by Domain Chinese Understanding system back to the segmentation vocabulary, realized the self-accomplished and positive interacted words segmentation in Domain Chinese Understanding system. Secondly, this text put forward a new mentality which applied the Clustering system to the Domain Orientation module of the Domain Chinese Understanding system, which accomplished the Domain-Orientating of the result of words segmentation. At the same time, this text applied the words clustering system to the feeding-back module of the Domain Chinese Understanding system. The words clustering system used the result of Domain Chinese Understanding system to self-training and self-accomplished step by step, finally accomplished the words clustering of words segmentation vocabulary, which improved the veracity and efficiency of the words segmentation and the Domain Chinese Understanding system. At last, the intelligent words segmentation and the Clustering system were applied to the mechanical product designing. It passed the system test and obtained good result.
