In order to integrate and query irregular and dynamic information on Web in a database like fashion, we use Object Exchange Model(OEM) ( OEM ) to construct information model of Web. 为了对Web上不规则的、动态的信息按照数据库的方式集成和查询,采用对象交换模型(OEM)(OEM)建立了Web上信息模型。
A framework for the representation of incremental information in OEM ( Object Exchange Model(OEM) ), a popular model for semi-structured data is introduced. 基于对象交换模型(OEM),提出了增量信息的数据建模框架。
An approach was developed to identify structures in semi-structured and hierarchical data using the OEM ( object exchange model ) and a pruning strategy to quickly extract simple paths from the OEM graph for integrating and querying semi-structured data. 该文提出一种基于OEM(ObjectExchangeModel)模型的半结构化数据的模式抽取算法,采用自顶向下的剪枝策略,可快速发现频繁简单路径集,应用于半结构化数据的集成及查询回答与优化。
Extends the OIM ( Object Model for Integration ) object algebra, and designs a practical OIM data exchange system model based on Java language. The proposed model makes full use of the advantages of both OIM object model and the object-oriented language. 扩展了OIM对象代数,提出一种基于Java的OIM数据交换系统模型,充分利用OIM对象模型与面向对象语言的配合优势,使系统性能得到保证。
The proposal of learning object makes it possible for the reusing, sharing and exchange of learning content. Metadata model describes the public property of various components and solve the exchange and retrieval problems of learning objects. 学习对象的提出为网络学习内容的重用、共享和交换的实现提供了可能,元数据模型描述了各类组件的公共属性,解决学习对象的交换和检索问题。
