基于本体的个人知识管理模型设计

Ontology-based personal knowledge management modeling

针对目前个人知识管理中存在的知识来源多样、存储分散、片段知识不便及时存储、基于关键词匹配而非语义检索等问题,采用本体方法建立了具有用户层、表示层、本体层和存储层4层结构的个人知识管理系统.用户请求经表示层转化为对本体的具体操作请求后发给本体层;本体层包含了本体定义、本体查询、本体更新的三大类接口访问存储层;存储层负责知识的存储.通过本体技术,能实现基于语义的个人知识管理.

Currently,several limitations existed in the field of personal knowledge management.For example,knowledge is usually gathered from diverse source with scatter storage,knowledge snippet cannot be stored promptly,and knowledge retrieval is based on simple keywords matching rather than semantic searching.This paper creates a new personal knowledge management model which is based on ontology method and composed of user,presentation,ontology and data storage layers.In the architecture,presentation layer converts user requests to concrete ontology operations and transmits them to ontology layer.Ontology layer accesses storage layer through three kinds of interfaces including ontology definition,searching and update interfaces individually.Storage layer can quickly store information.Through ontology technique,the new model supports semantic searching in personal knowledge management.
