利用语义信息集成技术解决企业内部信息孤岛问题

当前企业内部广泛存在信息孤岛的关键是因为信息的语义只对与数据源相关的应用程序和特定的用户是可理解的，而计算机无法理解和处理信息的语义。通过构建面向领域的全局本体来描述与领域相关的知识，并在各个分布异构的数据源与全局本体之间建立语义映射来消除数据源之间的语义异构，从而解决信息孤岛的问题。详细分析了利用语义信息集成的关键技术解决企业内部信息孤岛问题的过程和方法，并提出了一个用于解决孤岛问题的语义信息集成的体系结构。

APPLYING SEMANTIC INFORMATION INTEGRATION TO RESOLVE INFORMATION ISOLATE NODES INSIDE ENTERPRISE

The meaning of data sources is comprehensive to the related applications and special users but, computer, which is the key to the wide existence of isolated information nodes inside enterprise. The way to resolve problem of isolated information nodes is by constructing domain-oriented global ontology to describe the knowledge related to the special domain then set up mapping between heterogeneous and distributed data sources and global ontology to eliminate the semantic differences. In this article, the author analysed the key technology basis and methodology and put forward a semantic information integrated architecture to resolve problem of isolated information nodes.
