Abstract

Abstract: The data processed by semantic grid are often semi-structured data. Therefore, how to model and retrieve these semi-structured data is a key issue of semantic Web. The presenting model for semi-structured data base Resource Description Framework （RDF） and its information retrieval mechanism were proposed in this paper. Then a semantic grid infrastructure was described, which implemented knowledge sharing and retrieval in chemical engineering domain based on a chemical computing grid platform.

Key words: semantic grid, Resource Description Framework （RDF）, semi-structured data, information retrieval

摘要： 语义网格所需要处理的信息通常为半结构化数据，如何以合理的模型表示这些半结构化数据并实现高效查询处理，是语义网格要解决的核心问题之一。提出了一种基于资源描述框架（RDF）的半结构化数据表示模型，并设计了相应的信息检索机制。最后介绍了一个基于化工计算网格平台的，实现了化工领域知识共享与检索的化工语义网格架构的设计与实现。

关键词: 语义网格, 资源描述框架, 半结构化数据, 信息检索
