面向知识服务的知识库逻辑结构模型

Knowledge Service-oriented Model of Knowledge Base Logical Structure Research

由传统的文献信息服务,提升到用于解决实际问题的知识服务,必须以高效的知识获取作为支撑,有效地推动知识服务并拓宽其服务领域。文章从知识服务的角度架构知识库逻辑结构模型,分析知识库逻辑结构,并以知识获取为驱动来构建知识库逻辑结构的理论框架,探索结构一般规律,形成知识获取的新模式。根据推理范畴探究知识点之间存在的映射关系并提出知识的简约表示,解决了知识存储与知识推理两难问题;引入非数据的清洁度机制,保障了知识的简约表示的效用,使得能从知识库中获取满足清洁度的查询结果且适应不同知识服务的合理化需求,保障知识服务水平的提升。

High efficiency knowledge discovery, as supported by the process from information service to knowledge service which to solve actual problems, put forward to effectively promote knowledge service and widen the service field. The aim of this paper is to form the model of knowledge base logical structure on architecture from the perspective of knowledge service, to construct the theoretical framework of knowledge base logical structure driven by the knowledge discovery, and to protect high performance knowledge service, exploring the general law of knowledge base structures, and the formation of a new pattem of knowledge discovery. About the logical structure of knowledge base research is according to the following aspects： investigate the mapping relationship between knowledge points and raise a new simple knowledge representation based on reasoning ranges, settle a dispute between knowledge storages and knowledge reasoning, safeguard the utility of the simple knowledge representation by introducing the mechanism of data cleaning, obtain query results with a clean degree satisfying clean requirements of applications from knowledge base with the dirty data.
