Electronic markets have gained much attention as institutions to allocate goods and services efficiently between buyers and sellers. However, calculating suitable allocations between buyers and sellers in such markets can easily become very tricky, particularly if the services and goods involved are complex and described by multiple attributes.
This talk will present a semantic policy description framework that draws from utility theory to specify configurable products with multiple attributes. The framework thus allows the declarative description of seller pricing policies as well as buyer preferences over these configurations. As part of the framework, we present a machine-interpretable representation language for the policies and a method to evaluate different trading object configurations based on these policies. Buyers and sellers can then publish their policies, allowing an independent matchmaker to select the best service allocation based on the given buyer preferences and seller pricing policies.
The talk will also include a discussion of the various activities that are currently going at the University of Karlsruhe in the area of service sciences.
