    , d) selecting one or more clusters according to one or more criteria and aggregating the context values and quality measures of selected clusters to generate a single context value and single quality measure, wherein said single context value and single quality measure are usable by a context aware application to avoid conflict and ambiguity among different information sources providing said context data.
