针对研究中存在缺乏个体针对性、理论总结和应用结合不够、结构推理功能不强、真实性和安全性难以保证以及缺乏量化数据及实验支持等问题,本文对知识地图的概念体系及可视化服务机制进行了研究。首先介绍了知识地图的概念体系,包括知识的定义和特征、知识分类、空间知识、知识地图等,在总结知识地图的研究现状的基础上,指出了研究中存在的不足;然后,介绍了知识地图中知识库的多源数据特性、知识可视化的研究内容及针对个性化需求的定制、推荐、推送、自适应等服务机制,提出了知识地图可视化系统中知识库、符号库和模板库的构建方法,并进行了初步实践。
In connection with the lack of individual, combination of theory and application, also the difficulty to ensure the authenticity and safety, lack of quantitative data and experimental support in research , the paper studies the concept system of knowledge map and related visualization services mechanism. First, the authors introduce the concept system of knowledge map including the definition and characteristics of knowledge, the classification of knowledge, spatial knowledge and knowledge map, etc. Based on the research status of knowledge map, the authors point out the deficiency in research. Then the paper introduces the multi - source characteristics of knowledge database in knowledge map and the research of knowledge map visualization and service mechanism to meet the individual requirements. Finally, the authors propose the construct methods of the knowledge data- base, symbols database and templates database in the map visualization, and make an elementary practice.
