CCMF, Computational Context Modeling Framework - An Ontological Approach to Develop Context-Aware Web Applications

The purpose of software is to help people to perform their activities and fulfill their objectives. In this regard, the human-software relationship could be enhanced if software could adapt to changes automatically during its utilization (Brezillon, 1999). Context is defined by (Dey, 2001) as any type of information which characterizes an entity. An entity is any person, place or object that is relevant to the interaction between users and software. According to (Dey & Abowd, 1999) context-awareness is the capability of software to use context to offer services to users. For instance, a context-aware system may trigger an alarm in a device near to a user to remind him of the departure time of a planned trip (Yamato et al. 2011). In this example, context is used to provide a service to the user: the reminding of a personal activity. It is not, however, a trivial task to associate context with software in the same level of abstraction as humans do when they communicate with each other. (Dey & Abowd, 1999) considers that such ability is naturally inherited from the richness of the human languages and the common understanding of how the world works and from an implicit understanding of daily situations. Thus, with the intention of enhancing the offering of services from software to humans, it is important to transmit these capacities to computational environments.
