The increasing availability of massive information on the
Web causes the need for information aggregation by filtering and ranking
according to user´s goals. In the last years both industrial and academic
researchers have investigated the way in which quality of services can be
described, matched, composed and monitored for service selection and
composition. However, very few of them have considered the problem of
evaluating and certifying the quality of the provided service information
to reduce irrelevant information for service consumers, which is crucial to
improve the efficiency and correctness of service composition and execution.
This paper discusses several problems due to the lack of appropriate
way to manage quality and context in service composition and execution,
and proposes a research roadmap for reducing irrelevant service information
based on context and quality aspects. We present a novel solution
for dealing with irrelevant information about Web services by developing
information quality metrics and by discussing experimental evaluations.
