1. A method for determining an accuracy of location information that indicates a location at which social media content was created, the method being implemented in a computer that includes one or more physical processors programmed by one or more computer program instructions that, when executed by the one or more physical processors, program the computer to perform the method, the method comprising: obtaining, by the computer, a geofeed definition comprising an indication of one or more geographically definable locations; obtaining, by the computer, social media content items based on the geofeed definition, the social media content items aggregated from a plurality of content providers based on the indication of the one or more geographically definable locations, the social media content items being provided by the plurality of content providers based on respective requests formatted specifically for individual ones of the plurality of content providers, wherein the respective requests comprise the one or more geographically definable locations, and wherein the social media content items include at least social media content from a first one of the plurality of content providers; obtaining, by the computer, metadata associated with the social media content; determining, by the computer, first geotag data from the metadata, the first geotag data indicating: (i) an automatically derived location, or (ii) a manually input location where the content was created; identifying, by the computer, a geotag source related to the first geotag data, wherein the geotag source comprises a user profile of a content creator who created the social media content; obtaining, by the computer, non-profile-based geotagged content related to the one or more geographically definable locations, wherein the non-profile-based geotagged content is associated with second geotag data generated by a geotag source other than the user profile; identifying, by the computer, a profile location associated with the non-profile-based geotagged content based on location information defined in the user profile; determining, by the computer, whether the second geotag data associated with the non-profile-based geotagged content and the profile location match; and determining, by the computer, a confidence level based on the determination of whether the second geotag data associated with the non-profile-based geotagged content and the profile location match, wherein the confidence level is indicative of a likelihood that the first geotag data accurately describes a location where the social media content was created.
