At first system accomplishes chinese language automatic word segmentation and part - of - speech tagging through chinese input approach with word segmentation , then forms corresponding surface semantic network according to the semantic structure grammar , and finally gets corresponding data flow diagram and data dictionary according to the automatic generation algorithms of data flow diagram and data dictionary , the whole completion of the work , can not only provide a description environment of natural language for case , but also develop into the system which takes the question described on the basis of the natural language as the system ' s input 工作的中心是自然语言篇章理解。系统首先通过分词输入法实现汉语自动分词与词性标注,然后根据语义结构文法产生相应的表层语义网络,最后根据数据流图、数据字典自动生成算法转换为相应的数据流图和数据字典。这项工作的彻底完成,不仅可以给case提供一个自然语言的描述环境,而且可进一步发展为基于自然语言描述问题作为输入的系统。
