This thesis deals with the proposal of a framework and an architecture that allow the design and modeling of environments able to perceive the context-awareness through tagging. In this proposal, we have carried out an analysis of the domain related with the context-awareness. Thus, we have defined the relevant entities of the environment such as areas, devices, objects and users, as well as the contextual information acquired from the actions performed with these entities. In this way, the architecture can support and provide (implicit) adaptive services, not only to the user interacting with the entities in a certain moment, but also to other users; these users can receive context-awareness services subsequently, in a proactive way. On the other hand, the model includes a grammar to represent the dynamic behavior of the environment, a classification of the interactions, and mechanisms to implement the context-awareness services by means of tagging.

This Ph.D. Thesis pretends to provide a model for taking advantage of the actions carried out by the users and, in consequence, offer better services in an implicit way, helping in the development of user’s activities. Basically, these characteristics are activated by means of the link of contextual information with relevant entities of the environment, and by mechanisms to give the needed support for generating context-awareness services through tagging. Thus, the effort made by the users is reduced considerably.
