A system for prioritizing search results retrieved is described. One embodiment includes an inference, classification, and indexing subsystem configured to assign a local ranking to each occurrence of each data artifact in a collection of data artifacts obtained from on-line data objects, the local ranking assigned to each occurrence of each data artifact indicating a level of importance of that data artifact compared to other data artifacts obtained from the same on-line data object, the collection of data artifacts being indexed and organized by subject in at least one data structure, all data artifacts associated with a non-unique subject being associated with a single subject entry in the at least one data structure; and a search subsystem configured to assign, in response to the computerized search query, a global ranking to each data artifact in a set of data artifacts retrieved as search results from the collection of data artifacts, the global ranking of each data artifact in the set of data artifacts indicating a level of importance of that data artifact compared to the other data artifacts of like kind in the set of data artifacts, the global ranking of each data artifact in the set of data artifacts being based at least in part on the local rankings of the occurrences of that data artifact; prioritize the search results in accordance with the global rankings of the data artifacts in the set of data artifacts, the data artifacts of a given kind being grouped and arranged in descending order of global ranking; and present at least a portion of the prioritized search results to a user.
