Context through answer set programming
Angelo Rauseo, Davide Martinenghi, Letizia Tanca · 2011
In a world of global networking, the variety and abundance of information generates the need for effectively and efficiently gathering, synthesizing, and querying the available data while removing information noise. The concept of context has been developed and refined since the first approaches to ubiquitous computing [3], the research area of everywhere computing systems, which has the objective to provide help and information to users in an almost imperceptible way. At first, the idea of context was limited to time and location; later it was extended also to the other external environmental factors, current trends and phenomena that may change or influence the information and services available to a user. In this work, we refer to context primarily in relation with the effects that this notion has over data.
