Recent natural disasters have highlighted the need for disaster preparedness, planning, and management. Hurricane Katrina demonstrated the usefulness of Web sites in dealing with natural disasters. However, little is known about the necessary contents and structures of Web-based information systems for natural disaster management. In this paper, we focus on developing an ontology structure of elements...
Data modeling is one of the most important activities in the process of information systems development which is based on domain knowledge in specific area. This paper presents a system for analyzing data model correctness from both syntax and semantic aspect. The system is based on using ontology for domain knowledge representation, transformation of data models and ontology to predicate logic form...
In this paper, we present our definition of a particular ontology of the Civil Aviation Information System. Therefore we have a fundamental information framework for the whole system. We also show the mapping of models between OWL and XML, which are both quite useful. And with OWL-S, we describe and extend definition of web services in the system. All these not only unifies the information in the...
Web mining is the use of data mining technologies to automatically interact and discover information from Web documents, which can be in structured, unstructured or semi-structured form.

One major challenge for businesses today is the openning of their information systems (IS), making them accessible to their partners over the Internet. To this aim, they expose interfaces of their IS via Web wervice technology which consists in loosely coupled components using XML documents and commonly agreed standards to communicate.

The ontology is driven by two main design models: the conceptual and the application models. The application model extends the conceptual model with presenting data and inferring. During the presentation generation the input data goes through a...
