Fuzzy Ontology-based Semantic Integration of Heterogeneous Data Sources in the Domain of Watershed Analysis
نویسندگان
چکیده
In environmental research, data integration plays an important role given the increasing availability of heterogeneous data sources for specific features, such as soil type, climate, geographic location and so on. However, some of those features have inherently imprecise relationships and the lack of a suitable semantic model can be a major obstacle to its effective integration. In this context, this paper presents a semantic data integration system based on a fuzzy ontology, capable of perform query expansions based on imprecise aspects of real phenomena. We executed a real experience in the domain of watershed analysis. Consequently, watershed researchers obtained an homogeneous view of the data sources and more effective responses to their queries.

Query Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...

Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...
