Query Processing the Heterogeneous Information Sources using Ontology-based Approach
The problems of accessing and integrating heterogeneous information sources are becoming centerstage problems. One problem arising from accessing heterogeneous sources is semantic heterogeneity. In this paper, we propose a metadata dictionary based on domain ontology as an assistant mechanism for query processing the heterogeneous sources and resolving semantic heterogeneity. An XML-based data ...
متن کاملQuete: Ontology-Based Query System for Distributed Sources
The exponential growth of the web and the extended use of database management systems in widely distributed information systems has brought to the fore the need for seamless interconnection of diverse and large numbers of information sources. Our contribution is a system that provides a flexible approach for integrating and transparently querying multiple data sources, using a reference ontolog...
متن کاملOntology Based Integration of Distributed and Heterogeneous Data Sources in ACGT
In this work, we describe the set of tools comprising the Data Access Infrastructure within Advancing Clinico-genomic Trials on Cancer (ACGT), a R&D Project funded in part by the European. This infrastructure aims at improving Post-genomic clinical trials by providing seamless access to integrated clinical, genetic, and image databases. A data access layer, based on OGSA-DAI, has been developed...
متن کاملOntology-based information extraction and integration from heterogeneous data sources
In this paper we present the design, implementation and evaluation of SOBA, a system for ontology-based information extraction from heterogeneous data resources, including plain text, tables and image captions. SOBA is capable of processing structured information, text and image captions to extract information and integrate it into a coherent knowledge base. To establish coherence, SOBA interli...
متن کاملQuery Translation for Ontology-extended Data Sources
The problem of translating a query specified in a user data content ontology into queries that can be answered by the individual data sources is an important challenge in data integration in e-science applications. We develop the notions of semantics-preserving query translation and maximally informative query translation in such a setting. We describe an algorithm for maximally informative que...
