Model Formulation: semCDI: A Query Formulation for Semantic Data Integration in caBIG
OBJECTIVES To develop mechanisms to formulate queries over the semantic representation of cancer-related data services available through the cancer Biomedical Informatics Grid (caBIG). DESIGN The semCDI query formulation uses a view of caBIG semantic concepts, metadata, and data as an ontology, and defines a methodology to specify queries using the SPARQL query language, extended with Horn ru...
متن کاملSemantic Representation and Querying of caBIG Data Services
A computational grid infrastructure for biomedical research, called caGrid, is under development by the National Cancer Institute (NCI) as part of the cancer Biomedical Informatics Grid (caBIG) Initiative. In this paper we present a model that enables users to query an integrated view of caBIG data services at a conceptual semantic level. The model is based on semCDI, a formulation to generate ...

Query Rewriting for Semantic Web Information Integration
Though significant research has been done in the realm of information integration, continuously increasing amounts and complexity of data demand more advanced techniques for its access. Semantic Web technologies such as OWL and SWRL provide the capacity for rich definitions of data sources, global views, and the mappings between them. An information integration system based on these technologie...
متن کاملSemantic-Based Query Routing and Heterogeneous Data Integration in Peer-to-Peer Semantic Link Networks
A semantic link P2P network specifies and manages semantic relationships between peers’ data schemas. The proposed approach includes a tool for constructing and maintaining P2P semantic link networks, a semantic-based peer similarity measurement approach for efficient query routing, and peer schema mapping algorithms for query reformulation and heterogeneous data integration. The advantages of ...
