With the rapid development of Internet technology, web information system has achieved great development, and XML, as the new carrier and standard of information exchanging and calculating on the internet, has been widely used as well. While providing a uniform syntax and semi-structured data model, XML does not express semantics but only structure. This paper combines the web data integration problem...
This research utilized software agent based technology in expanding remote machine tool service system by constructing related remote service ontologies to facilitate its smart and distributive characteristics. These service agents could be used for remote smart machine tool services underlying Internet through the communication protocols supported by both KQML (Knowledge Query Manipulation Language)...
In this paper we propose a hierarchical data model for representing ontologies. The model is suited for efficiently handling hierarchical relationships, frequently found in the ontology structure. Our hierarchical data model defines a generic representation using hierarchies that can be persisted in a general purpose records structure. We introduce two algorithms that efficiently represent the hierarchical...
The Web has become the largest information source, which includes all aspect of human's life. The myriad information is believed to be hidden behind the deep Web, which the search engines and crawlers can't access directly. To extend the human's physical limitation of accessing information, the information fusion system is introduced. The Web is very different from the traditional database community,...
The explosion of the Internet in recent years has caused the need of the association between different industries and branches to achieve communication and information sharing. However various heterogeneities exist between different data sources, especially semantic heterogeneities because the same data was modeled by different users in different ways. This paper mainly imported the concept of ontology...
