14. A system comprising: one or more computing devices operable to perform operations comprising: receiving a search query, the search query including one or more terms that include a name corresponding to one or more individuals; identifying a plurality of search results responsive to the query, wherein the plurality of search results includes a first search result, the first search result corresponding to a cluster of social media resources associated with a particular individual of the one or more individuals, and wherein each resource in the cluster of resources is associated with a corresponding cluster identifier that identifies the cluster of resources; providing for presentation the first search result and one or more other search results of the plurality of search results; receiving user feedback for the first search result that identifies the cluster of resources associated with the particular individual, wherein the feedback provides an indication of the accuracy of the cluster of resources; and processing the received feedback to determine whether to modify the cluster of resources associated with the particular individual, where the processing includes assigning a weight to the user feedback, where the weight of the user feedback is determined based at least on one or more factors associated with the user, and where the one or more factors include a level of a social connection between the user and the one or more individuals.
