智能化专题地图内容选择的研究

Study on Intelligent Content-Determination of Thematic Map

首先详细阐述了智能化专题地图内容选择的基本理论问题;然后提出了一种“启发式”和“增强型智能化”相结合的问题解决方法并讨论了问题的分解策略和专题内容选择的质量评价方法;接着设计了试验系统的概念框架并建立了问题的知识模型,提出了用关系数据库的理论与方法模拟知识模型,为知识的获取提供了模式,为知识库的构建提供了方法;最后基于WebService开发了试验系统并举例说明了问题。

Intelligent cartography is the developing tendency. This paper manly concerns the intelligent contentdetermination of thematic map, which is an important part of thematic map design. Firstt＇ the fundamental theory of intelligent content-determination of thematic map is illustrated from three aspects： ＂What＂, ＂Why＂ and ＂What is to be done＂. Secondly, a problem-solving method called ＂heuristic＂ with ＂intelligence amplified＂ is presented to answer the ＂How＂ question. On this basis, the decomposition of the problem and quality evaluation of thematic content are discussed. Thirdly, the conceptual framework of the experimental system is designed and the knowledge model is modeled. A method that uses relational database to imitate knowledge model is presented for knowledge acquisition and knowledge base construction. Finally, the experimental system is developed based on WebService, and then an example is given to illustrate it.
