What is global ontology?

What is global ontology?

The global ontology is constructed based on the associated concepts in Wikipedia Thesaurus, and provides efficient mappings among the distributed Web ontologies. To construct such a global ontology, the main task is how to extract relations for associated concepts.

What is ontology based data access?

Ontology Based Data Access (OBDA) is a prominent approach to query databases which uses an ontology to expose data in a conceptually clear manner by abstracting away from the technical schema-level details of the underlying data.

What is ontology in data management?

An ontology is a formal description of knowledge as a set of concepts within a domain and the relationships that hold between them. However, unlike taxonomies or relational database schemas, for example, ontologies express relationships and enable users to link multiple concepts to other concepts in a variety of ways.

What is ontology driven?

It brings state-of-the-art ontology reasoning into mainstream software development and its languages. Ontology Driven Software Development is the essential, comprehensive resource on enabling technologies, consistency checking and process guidance for ontology-driven software development (ODSD).

What is ontology and its different types?

“…an ontology is a formal naming and definition of the types, properties, and interrelationships of the entities that really or fundamentally exist for a particular domain of discourse. “An ontology is a formal, explicit specification of a shared conceptualization.”

Is an ontology a database?

An ontology database is a basic relational database management system that models an ontology plus its instances. To reason over the transitive closure of instances in the subsumption hierarchy, for example, an ontology database can either unfold views at query time or propagate assertions using triggers at load time.

What is ontology and its types?

What does ontology-based data access ( Obda ) mean?

Ontology-based Data Access (OBDA) is a new paradigm, based on the use of knowledge representation and reasoning techniques, for governing the resources (data, meta-data, services, processes, etc.) of modern information systems.

What does Obda stand for in Semantic computing?

“Optique System: Towards Ontology and Mapping Management in OBDASolutions,” in Proc. Semantic computing for big data: approaches, tools, and emerging directions (2011-2014) This was developed by Philippi-Hagenbuch of Peoria using the On-board Data Acquisition System (OBDAS) and was tested by CANMET.

How are Obda systems used in the real world?

OBDA Systems proposes state-of-the-art solutions based on the most recent innovations in the field of semantic technologies to provide its clients with a direct and effective means for extracting key data from large and complex datasets. The foundation of these solutions is representation and reasoning through ontology modelling.

How is Obda a form of information integration?

OBDA can be seen as a form of information integration, where the usual global schema is replaced by the conceptual model of the application domain, formulated as an ontology.
