I am going to present a work about the use of ontologies in the Ubiquitous Computing area. Our work is general, and it is not an specific proposal of a new ontology in a new ubiquitous application. We have made an study about different uses of ontologies in this field, and we propose a taxonomy to classify these works.

Ubiquitous Computing Generic Ontologies : Have the ambitious objective of modelling the complete Ubiquitous Computing body of knowledge.
Ubiquitous Computing specific ontologies : Only attempts to conceptualize one part (sub-domain) of this discipline, of interest for a determined goal, collective, or moment.
Generic Ontologies of Ubiquitous Computing Domain (Example)
SOUPA ( Standard Ontology for Ubiquitous and Pervasive Applications ) : Combines many useful vocabularies from different consensus ontologies (Chen et al., 2004)
Specific Ontologies of Ubiquitous Computing Domain (Example)
FIPA Device Ontology : Can be used as reference to express the capabilities of different devices in an ubiquitous computing system. (Foundation for Intelligent Physical Agents, 2001)
Ontologies as Software Artifacts in Ubiquitous Computing Applications
Ontologies as software artifacts at development time : Includes the ontologies used as artifacts in software development and maintenance, or in other complementary activities of the development: support activities, project management, knowledge reuse, etc
Ontology-driven applications : When ontologies are part of the system software architecture, as an additional component, cooperating with the rest of the system at run time to attain the software objective
Ontology-aware applications : Are used by the software during run time for a specific purpose, as an information resource, normally remote, upon which the software operates, carrying out, for example, specific queries.
GAS Ontology : Conceptualises the Gadgetware Architectural Style (GAS), which supports the composition of ubiquitous computing applications from everyday physical objects enhanced with sensing, acting, processing and communication abilities (Christopoulou et al., 2004)
GAIA Pervasive Computing Environment : A smart spaces framework, using an ontology server to get the interoperability among different entities, the semantic discovery and matchmaking of the arrival and departure of mobile entities in the environment, and the context-awareness in ubiquitous computing systems (Ranganathan, 2003)
Ontology as database substitute : Mapping relational databases into ontologies, using a mapping processor for generating the ontology and for the execution of queries on the ontology. This refers to facilitate the transformation of the applications that use a relational database to allow semantic access to the content available in the database. (Barrasa, 2006)
