  bibo_abstract:
  - 'We consider a market where final products or services are compositions of a number
    of basic services. Users are asked to evaluate the quality of the composed product
    after purchase. The quality of the basic service influences the performance of
    the composed services but cannot be observed directly. The question we pose is
    whether it is possible to use user evaluations on composed services to assess
    the quality of basic services. We discuss how to combine aggregation of evaluations
    across users and disaggregation of information on composed services to derive
    valuations for the single components. As a solution we propose to use the (weighted)
    average as aggregation device in connection with the Shapley value as disaggregation
    method, since this combination fulfills natural requirements in our context. In
    addition, we address some occurring computational issues: We give an approximate
    solution concept using only a limited number of evaluations which guarantees nearly
    optimal results with reduced running time. Lastly, we show that a slightly modified
    Shapley value and the weighted average are still applicable if the evaluation
    profiles are incomplete.@eng'
