The use of mediation and ontology technologies for software component information retrieval

Regina M. M. Braga, Marta Mattoso, Cláudia M. L. Werner
2001 Software engineering notes  
Through mediators, domain ontology acts as a technique/formalism for specifying ontological commitments or agreements between component users and providers, enabling more accurate software component information  ...  We present a component information integration data layer, based on mediators.  ...  Usually a query engine is available in HDDS and therefore ad hoc queries over this metadata can be used to analyze the available components.  ...

Feature Analysis of Ontology Mediation Tools

Ravi Lourdusamy, Gopinath Ganapathy
2008 Journal of Computer Science  
Ontology mediation includes operations such as, mapping, alignment, matching, merging and integration.  ...  It provides the researchers a comprehensive understanding of methods and tools intended for ontology mediation.  ...  If the user wants to expand his query over different ontology servers, the original query needs to be translated from the vocabulary of the user's ontology into the vocabulary of another's component ontology  ...

Information Integration Via an End-to-End Distributed Semantic Web System [chapter]

Dimitre A. Dimitrov, Jeff Heflin, Abir Qasem, Nanbor Wang
2006 Lecture Notes in Computer Science  
A distributed, end-to-end information integration system that is based on the Semantic Web architecture is of considerable interest to both commercial and government organizations.  ...  Prototype System Architecture The ISENS system prototype consists of three main components: the Web Interface Component (WIC), the Distributed Querying System (DQS), and the Distributed Enabling Component  ...  The DQS component processes each SPARQL query and enables data integration over different, distributedly located, ontologies. The DQS contains a set of source descriptions.  ...

Query processing in a three-level ontology-based data integration system

João C. Pinheiro, Vânia M. P. Vidal, José A. F. Macêdo, Eveline R. Sacramento, Marco A. Casanova, Fábio A. M. Porto
2010 Proceedings of the 12th International Conference on Information Integration and Web-based Applications & Services - iiWAS '10  
First, the query is decomposed, using the mediated mappings, into a set of elementary sub-queries expressed in terms of the application ontologies.  ...  In our approach, the mediated schema is represented by a domain ontology, which provides a conceptual representation of the application.  ...  These experiments will provide empirical evidences of the scalability of our query answering approach using sets of very large ontologies.  ...

Configuring Intelligent Mediators Using Ontologies [chapter]

Gennaro Bruno, Christine Collet, Genoveva Vargas-Solar
2006 Lecture Notes in Computer Science  
A user specifies a needs expression in terms of (i) an interesting view over a given application domain, (ii) sources preferences and (iii) architectural requirements.  ...  A configured mediator can therefore be adapted in order to build knowledge-based mediation systems with an arbitrary architecture.  ...  A user formulates a query over its mediation ontology and the query is evaluated over the mediator resources in a transparent way.  ...

Ontology-based data integration methods: a framework for comparison

Agustina Buccell, Alejandra Cechich, Nieves R. Brisaboa
2005 Revista Colombiana de Computación  
Keywords: Data Integration, Ontology, Semantic Heterogeneity.  ...  A data integration system provides a uniform interface to distributed and heterogeneous sources. These sources can be databases as well as unstructured information such as files, HTML pages, etc.  ...  Specifically, the mediator uses the articulations in order to translate queries over its own ontology to queries over the ontologies of the articulated sources.  ...

Context Aware Information Retrieval for Enhanced Situation Awareness

Ali Bahrami, Jun Yuan, Paul R. Smart, Nigel R. Shadbolt
2007 MILCOM 2007 - IEEE Military Communications Conference  
These factors can be used to shape both the execution of user queries and the form in which retrieved information is packaged.  ...  The approach lays on five intertwined fundamental concepts, namely Workflow, Context, Ontology, Profile and Information Aggregation.  ...  Governments are authorized to reproduce and distribute reprints for Government purposes notwithstanding any copyright notation heron.  ...

2008 BMC Bioinformatics  
Results: In this paper, we describe the Ontology-Based Mediator developed in the Amine System Project (http://asp.uma.es) using the infrastructure of Semantic Directories, and how this system has been  ...  Conclusions: This infrastructure is used to publish and manage not only ontologies and their relationships, but also metadata relating to the resources committed with the ontologies.  ...  Both G and S are expressed in languages over alphabets comprised of symbols for each of their respective relationships. The mapping M consists of assertions between queries over G and queries over S.  ...

2007 18th International Conference on Database and Expert Systems Applications (DEXA 2007)  
To successfully retrieve data described by RDF-based ontologies, the query language SPARQL is currently being developed at W3C.  ...  For a large-scale data integration, which is the scope of a middleware developed within the Austrian Grid project, it is necessary to execute queries on distributed data nodes.  ...  However, for efficient distributed query processing pipelining will be necessary. Figure 1 . 1 Mediator-wrapper architecture.  ...
