dc.description.abstract | Data is a modern commodity. Electronic data market places are being designed and deployed. Yet current pricing models either focus on processing or are proprietary, opaque and not conducive of a healthy commodity market dynamics. In this paper we propose a generic data pricing model that is based on minimal lineages, i.e. sets of tuples contributing to the result of a query. We show that the proposed model fulfils desirable properties such as contribution monotonicity, bounded price and arbitrage-freedom. We extend the model to the case of probabilistic databases in the X-tuple model. We propose algorithms to the compute the price of a query based on our pricing models. | en_US |
