Then we made a comparison and analysis with the several main formal models and methods of system , such as basing on statistics , basing on meaning , basing on concept , basing on knowledge etc , the dissertation put forward a summarized method combined statistics with some semantic relations . this method combined the technology of statistics based on with the technology of meaning based on . it aimed at texts of science and technology 接着本文通过对现阶段几种主要的自动摘要技术:基于统计的自动摘要方法、基于自然语言理解的文摘方法、信息抽取、基于结构的自动摘要方法的比较和分析,得到它们自身的优点和缺点,并在此基础上提出一种主要基于传统的统计技术,并结合一定的语义关系的摘要方法。
The conclusion of this research can be listed as follows : 1 . case ' s phase - levels thoughts has been rigorously verified by the children ' s cognition ( daily mathematical practice and spatial construction ) and social cognition ( understanding of social meaning ) in min - developed region , has not been demonstrated in undeveloped region . 2 ( 5 )自创中心概念结构术语,将此定义为一种语义结和语义关系的网络( anetworkofsemanticnodesandrelations ) ,这些网络代表了儿童在某一领域范围并能运用于该领域所有认知任务核心知识。
In order to solve the problem of symbolic representation in geographic concepts and their mutual relationships , the geometrical composition of symbols of large scale topographic maps and the semantic and geometrical relationships among symbols are analyzed , the symbols system of topographic maps is regarded as a two - dimensional graphic language , and the relationship between symbols and geographic concepts is discussed 摘要为了解决地理概念及其相互关系的符号化表达问题,分析了大比例尺地形图符号的几何构成及符号间的几何和语义关系,把地形图符号系统作为一种二维图形语言,讨论了它和地理概念之间的关系。
