In large-scale distributed information systems, where participants (consumers and providers) are autonomous and have special interests for some queries, query allocation is a challenge. Much work in this context has focused on distributing queries among providers in a way that maximizes overall performance (typically throughput and response time). However, participants usually have certain expectations with respect to the mediator, which are not only performance-related. Such expectations mainly reflect their interests to allocate and perform queries, e.g. their interests towards: providers (based on reputation for example), quality of service, topics of interests, and relationships with other participants. In this context, because of parti...
