Paper Abstract:
|
Ontologies has as main objective to represent domains, providing semantic data and capacity to manage knowledge in computer systems. Althought there are standards for representing ontologies, such as OWL language, the full use of ontologies in computational systems is still restricted because the limitations found in persistence tools that are actually available, such as loss of performance in the conversion process of ontologies to relational databases, limitations related to the horizontal scalability, limiting the use of the same ontology between nodes in a geographically distributed network or the limitations related to querying and reasoning capabilities of the databases used in this tools, these are some of important features required by ubiquitous systems. This article describes a software architecture, that based on CouchDB database, aims to provide a distributed solution to store semantic data based on ontological models using standard query languages, such as SWRL and SQWRL, therefore allowing the use of semantic data in a distributed network, be it composed of fixed or mobile nodes. |
