User driven multi-criteria source selection

The paper describes and motivates the approach, presenting a methodology for modelling a user's context, and its collection of optimisation algorithms for exploring the space of solutions, and compares and evaluates the resulting algorithms using multiple real world data sets. The experiments show how source selection results are produced that are attuned to each user's preferences, both with respect to overall weighted utility and through faithful representation of a user's preferences within a result, while scaling to potentially thousands of sources.
