Ubiquitous Supervisory System Based on Social Contexts Using Ontology

Ontology Verification Using Contexts

Ontologies have become the de-facto modeling tool of choice, used in a variety of applications and prominently in the Semantic Web. Their design and maintenance, nevertheless, have been and still are a daunting task. As a result, ontologies quickly become underspecified. Therefore, if ontologies do not evolve, the semantic infrastructure of the information system can no longer support the chang...

Ontology Alignment Using Multiple Contexts

Ontology alignment involves determining the semantic heterogeneity between two or more domain specifications by considering their associated concepts. Our approach considers name, structural and content matching techniques for aligning ontologies. After comparing the ontologies using concept names, we examine the instance data of the compared concepts and perform content matching using value ty...

Ubiquitous Healthcare System Using Context Information Based on the DOGF

This paper proposed the Ubiquitous Healthcare System using context information for the personalized healthcare services in a home network environment. The context information is generated by location, health and home environment information collected from sensors/devices equipped in home. This system is designed on the Distributed Object Group Framework (DOGF) supporting the interfaces for invo...

Speech Recognition System Using DHMMs Based on Ubiquitous Environment

Most commercialized speech recognition systems that have a large capacity and high recognition rates are a type of speaker dependent isolated word recognition systems. In order to extend the scope of recognition, it is necessary to increase the number of words that are to be searched. However, it shows a problem that exhibits a decrease in the system performance according to the increase in the...
