Enabling ontology evolution in data integration

Haridimos Kondylakis, Dimitris Plexousakis
2010 Proceedings of the 1st International Workshop on Data Semantics - DataSem '10  
In this dissertation, we provide a solution that allows query answering under evolving ontologies without mapping redefinition. This is achieved by exploiting query rewriting.  ...  We elegantly separate the semantics of query rewriting for different ontology versions and for the sources and we present a module that enables ontology evolution over traditional ontology-based data integration  ...  Under these circumstances, the query rewriting in GAV approach is quite easy (it is illustrated in the Fig. 12) .  ...

Query Rewriting in RDF Stream Processing [chapter]

Jean-Paul Calbimonte, Jose Mora, Oscar Corcho
2016 Lecture Notes in Computer Science  
In this paper we propose a different approach for querying RDF streams over ontologies, based on the combination of query rewriting and stream processing.  ...  While RDF Stream Processing (RSP) has focused so far on extending SPARQL for continuous query and event processing, stream reasoning has concentrated on ontology evolution and incremental materialization  ...  Supported by Ministerio de Economía y Competitividad (Spain) under the project 4V: Volumen, Velocidad, Variedad y Validez en la Gestión Innovadora de Datos (TIN2013-46238-C4-2-R)  ...

Using Ontologies for Semantic Data Integration [chapter]

Giuseppe De Giacomo, Domenico Lembo, Maurizio Lenzerini, Antonella Poggi, Riccardo Rosati
2017 Studies in Big Data  
Here, we focus on a specific paradigm for semantic data integration, called Ontology-Based Data Access (OBDA).  ...  While many approaches exist for both ontology evolution [49] and database schema evolution [45] , to the best of our knowledge, no previous study has analyzed evolution in the presence of a mapping  ...  Current challenges In this section we discuss the main challenges related to OBDA that are currently under investigation. Query rewriting optimization.  ...

Improving Data Management using Domain Knowledge

2018 Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence  
First, we consider the problem of ontology-mediated query answering (OMQA), where queries in a standard database query language are enriched with an ontology expressing background knowledge about the domain  ...  of interest, used to retrieve more complete answers when querying incomplete data.  ...  Rewriting techniques In the context of OMQs, query rewriting is the following problem. Assume that a standard database query language L has been fixed as target language.  ...

Semantic Integration of Collection Description

Irene Lourdi, Christos Papatheodorou, Martin Doerr
2009 D-Lib Magazine  
Within those settings, we discuss five different cases studies that illustrate the use of ontologies in metadata representation, in global conceptualization, in high-level querying, in declarative mediation  ...  In this paper, we discuss the use of ontologies for data integration. We consider two different settings depending on the system architecture: central and peer-to-peer data integration.  ...  Query processing in a hybrid peer-to-peer system uses the global ontology as a declarative mediator for query rewriting between peers. Mapping Support.  ...
