They change rapidly and continuously due to the appearance and disappearance of devices, people and changes in their situation. These changes need to be reflected in the context information which is collected and maintained by the Ambient Intelligence applications. In this work we present a semantic infrastructure whose context information can be dynamically enriched and extended by the dynamically discovered objects in the environment, and which enables to reason over it.}, number = {51}, urldate = {2013-01-16}, booktitle = {3rd {Symposium} of {Ubiquitous} {Computing} and {Ambient} {Intelligence} 2008}, publisher = {Springer Berlin Heidelberg}, author = {Almeida, Aitor and L\xf3pez-de-Ipi\xf1a, Diego and Aguilera, Unai and Larizgoitia, Iker and Laiseca, Xabier and Ordu\xf1a, Pablo and Barbier, Ander}, editor = {Corchado, Juan M. and Tapia, Dante I. and Bravo, Jos\xe9}, month = jan, year = {2009}, keywords = {Artificial Intelligence, Data analysis, ISI, ambient intelligence, intelligent environments, middleware, ontologies, semantic inference, smartlab}, pages = {265--273}, } ']
