语义Web和语义网格及数据资源整合的探讨

目前,许多电子政务系统面临着一个共同的问题,这就是所谓的＂信息孤岛＂问题,解决该问题的关键是如何将现有数据资源进行有效的整合。而语义网格理论的提出,为这一难题的解决提供了一个新的思路。应用语义网格理论,针对出租汽车管理信息化的应用需求,构造语义网格模型Tx-Grid,并且讨论一种利用本体整合分布式异构数据库资源的机制,有效地解决这一问题。

Discussion on Semantic Web and Semantic Grid and Data Resources Integration

At present,many e-govenment systems are up against a common problem,namely information island.The key for solving the problem is to integrate the data sources in existence.The semantic grid theory which combines semantic Web and the grid brings us a new method to do the job.Based on the theory,puts forward a prototype of semantic grid called Taxi Grid（Tx-Grid） according to the application requirement of informationzation of Taxi management,and discusses a mechanism that integrates heterogeneous distributed database resources by using ontology to solve the problem efficiency.
