A recommender system can be analyzed to determine various performance characteristics of an online content service provider. The recommender system is analyzed using a predetermined policy, to determine if it satisfies such policy, and/or has other measurable intended and/or unintended biases. The policy can include such parameters as whether a particular profile is presented with certain particular types of items by the recommender system. The reliability of search engines can also be tested using a similar approach. |
