The Application Of The Noun Cluster Of NLU Discourse In The Domain Of Test And Measurement

This text applies the Noun Cluster Of NLU Discourse in the domain of Test and Measurement Technology, especially does more research on the progress noun cluster in discourse, through understanding and analyzing to the user's needs that are expressed in the form of natural language, and transform analysis result into the designing requirement of the concept or design parameter, offer a good design environment to user and designer. The main work done in this paper is as following:Introduce several theories and methods of NLU knowledge expression, and then give a new method to express knowledge, which combined by those methods. It uses "concept" including its intension and extension as the kernel, it also uses a framework and has a hierarchy structure like tree structure, and it shows the association of concepts. In the end, the method is used to construct a knowledge base and some rules. Classify the relations of noun concept in discourse; Secondly, analyze the inherent form of main-body in discourse --concept; Third, use concept as the foundation, then analyze the relations of concept and its attribute concept and the relations of connotation and extension; statement the methods of the analysis of the noun cluster in discourse; Also the core-word theory is presented; At last, the concept's association analysis method is developed for the deep discourse association problems. Implement the domain NLU discourse noun cluster analysis. The whole framework is introduced first, and then shows the method of noun cluster and the method of noun attribute concrete.Analyse the relations deeply of the concept by noun cluster, and analyze the discourse core word by the consequence of noun cluster. At last, the discourse noun cluster in NLU analysis is applied to the Test and Measurement expert system of the Man-machine interface. Meanwhile, the knowledge database and some rules of discourse analysis are established.The coming NLU system should using the internet resource, and realize using a way of collaboration of a few sub systems, every sub system has its special domain knowledge, the whole system is finished by every system dealing with a special domain and the whole system can deal with most NLU problems.
