煤炭资源信息共享中语义检索的研究与实现

The Research and Implementation of the Semantic Retrieval in Coal Resources Information Sharing

分析了当前我国煤炭资源的特点,构建了网络煤炭资源信息共享平台,以操作异构、数据表示异构、知识内容孤立3个层次的问题为核心,利用本体规范建设技术、传统关系数据库向本体映射的技术和对本体查询的技术,分别实现了表述形式一致、查询形式一致和信息知识互联,从而不仅实现了煤炭资源信息的极大共享,同时针对当前煤炭资源的特点,为用户提供了科学合理的智能化辅助决策。

This paper analyzes the features of our country＇s coal resources at present, establishes a platform for network coal resources information sharing, and taking the problems on three levels of the operation isomerism, data presentation isomerism and knowledge content isolation as the cores, and by using the ontology-based standardized construction technology, traditional relation database＇s ontology mapping technology and ontology-based inquiry technology, realizes respectively the uniformity of representing forms, the uniformity of query forms and interconnection of information knowledge, and therefore not only realizes the maximum sharing of coal resources information sharing but also provides scientific and rational intelligentized decision-making support based on the features of current coal resources.
