Abstract
Semantic caching has been extensively adopted in many mediation systems in order to improve their performance. In fact, without using a caching approach, mediators can suffer from several issues primarily related to sources unavailability and network congestion. Which might leave the final users encountering a high response and can sometimes be even unable to get answers. Nevertheless, the integration of a semantic cache in a mediation system might introduce some additional costs that should be taken into consideration. In this paper, we propose new algorithms that fall within this scope. Our approach relies on computing horizontal, vertical and semantic coverages provided by semantic regions to identify those regions that contain a significant portion of the user query results.
