چکیده
For Mass, distributed, heterogeneous data sources of petroleum engineering, this paper presents an petroleum engineering semantic-based data integration technology based on building global semantic mode. PSDT builds a global semantic data model which appropriate to the domain of Petroleum engineering by ontology extraction, ontology mapping, ontology merging, ontology evolution and constraint reasoning for domain data model. Users and upper applications can have a direct access to underlying complex data sources through the global semantic data model. This study integrates the Ontology to build the global semantic data model for the distributed, heterogeneous and complex semantic correlation data source and to provide comprehensive, real-time data services. Experiments have shown that this method is feasible and effective.

An Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...

متن کاملFuzzy Ontology-based Semantic Integration of Heterogeneous Data Sources in the Domain of Watershed Analysis
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...
