Ontology based data access
Weban OWL ontology as well as an ontology-based data access method is presented, which both are prerequisite for OPC UA integration into Linked Factory Data. Usually, the information in an ontology is stored in a graph-based triplestore and is not changing frequently over time. In industrial processes, run-time data, like sensor data or Webof ontology-based data access and ontology-based access control are presented, the proposed conceptual model is detailed in Section 3. Finally, Section 4 concludes the paper and summarizes the future directions of the presented study. 2 RELATED WORK The relation between database and Semantic Web is a frequently studied impressive topic in …
Ontology based data access
Did you know?
WebOntology-based data access (OBDA) is a data integration framework where data is accessed using queries on the ontology layer, and in turn, a set of mappings guide the data access on the underlying relational layer. This process is usually done via query rewriting wrt. ontology and query unfolding wrt. mappings respectively. WebOntology-Based Data Access could be seen as an application scenario of ontologies, yet it is also intricately linked with ontology engineering due to the representation limitations …
WebUsually, each of them utilizes a relational database system with a different proprietary schema. Semantic integration and access to the data is hardly possible. This paper describes ways of using Ontology Based Data Access (OBDA) for bridging the semantic gap between existing raw data and user-oriented views supported by ontology-based …
http://www.ghxiao.org/talks/2014-csws-obda-talk.pdf WebIn ontology-based data access (OBDA), an ontology is connected to autonomous, and generally pre-existing, data repositories through mappings, so as to provide a high-level, conceptual view over such data. User queries are posed over the ontology, and answers are computed by reasoning both on the ontology and the mappings.
Webover the ontology into data-level queries which can be executed by the underlying database management system. The paper is focused on the main principles of OBDA applied to Energy Technology Database within technology forecasting information system.
