一种用于蔬菜供应链知识检索的元数据模型

Metadata Model Used for Intelligent Knowledge Searching of Vegetable Supply Chain

知识的组织和分类对于智能检索系统十分重要,在调查分析的基础上提出了一个用于蔬菜供应链知识智能检索的元数据模型。这一元数据模型包含了蔬菜供应链知识库中的知识,知识库中的领域概念及用户分类,在元数据模型中将它们组合成一个整体。这一模型是实现蔬菜供应链知识共享和知识重用的基础。用OWL对元模型进行了形式化的表示,并在此基础上实现了蔬菜供应链知识智能检索系统。

Knowledge organization and classification is important for an intelligent searching system.A metadata model for the intelligence searching of vegetable supply chain knowledge is proposed based on investigation.The model contains the knowledge of vegetable supply chain knowledge database,the domain concepts and user classification.It integrates them as a whole.The metadata model is the base of knowledge sharing and reusing for vegetable supply chain.It formalizes the model by OWL and implements the intelligent searching system.
