The Research And Implementation Of The Intelligent Words Segmentation In Domain Chinese Understanding And Its Application In Products Designing

This paper designed and realized the system of intelligent words segmentation and the module of unknown word recognition in Domain Chinese Understanding, then applied it in the product design process. Based on the Domain Chinese Understanding System,this system transform the user's requirement expressed in the form of natural language into the designing requirement of the Concept Design or design parameter.Firstly, this paper analyzed the advantage and disadvantage of existing words Segmentation methods,and 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.This system produced all possible words segmentation results in the Automatic Words segmentation stage, and excluded the improper results of words segmentation with lexical analysis, then excluded the rest improper results of words segmentation with semantic analysis in the following Domain Chinese Understanding system modules, at last, at last, it utilized the feeding-back module to fed the results 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 paper mainly studied the recognition of Chinese names and institution names in the unknown word recognition module,then put forward a method based on statistic and rules which was used to solve the recognition of Chinese names,and another method based on the template matching which was used to resolve institution's recognition.At last, the system of intelligent words segmentation and the module of unknown word recognition were applied to the mechanical product designing. It passed the system test and obtained good result.
