SOUPA: standard ontology for ubiquitous and pervasive applications

Abstract

We describe a shared ontology called SOUPA -Standard

Context-Aware Service Composition in Pervasive Computing Environments

“…Among recent approaches to ontology-based context modeling, SOUPA [5] and CONON [29] define two-level ontologies for context modeling. A core ontology defines generic concepts that are usually modeled in context such as platform or users, while more specific ontologies introduce concepts for a particular application domain such as characteristics of users and devices, and location (vertical extensions), or the definition of intelligent environments such as home or office (horizontal extensions).…”

“…We do not enforce the use of a specific context ontology, any existing OWL-based context ontology can be used (e.g., [18,5,29,17]). What we define is a model for services and tasks enabling context-aware service composition.…”

“…Further information about the use of the simulation mode is given in Section 4.2. The context manager can be a central entity that aggregates the heterogeneous information provided by various entities in the environment [5], but it can also be distributed [14]. A distributed context manager can be a set of collaborating intelligent agents that exchange context knowledge fragments to synthesize context information.…”

“…In particular, various models have been proposed to represent context information, among which attributes and values models, object oriented models and ontologies. Ontologies have proved to be the most suitable model for representing and reasoning on context information for the following reasons [5] : (i) ontologies enable knowledge sharing in open, dynamic systems; (ii) ontologies with well defined declarative semantics allow efficient reasoning on context information; and (iii) ontologies enable service interoperability and provide the means for networked services to collaborate in a non-ambiguous manner. The Ontology Web Language (OWL 1 ) is a recent W3C Most existing approaches to context-aware systems propose either a user-centric or a service-centric view of context.…”

An Agent-Oriented Programming Language for Computing in Context

“…They are responsible for the specification of the domain knowledge, and as they can be expressed logically, they can be the basis for sound reasoning in the specified domain. Several ontologies are being proposed for the development of specific applications [6,14,7,22]. Description logics are at the core of widely known ontology languages, such as the Ontology Web Language (OWL) [13].…”
