Abstract: Systems, methods, and computer-readable storage media for performing entity-based aggregation of endorsement data are provided. Entity-endorsement data is received from a plurality of different sources, e.g., websites, web pages, database records, files, data feeds, or networks. Entity resolution is then performed to identify like entities. Once the entities are resolved, the relevant endorsement data from each appropriate source is aggregated. The aggregated endorsement data may then be presented with or without an identification of the sources from which the data was aggregated. In this way, sparseness and fragmentation of endorsement data are mitigated and a more complete picture of an entity's endorsement status may be seen.
