Methods and systems that improve the ability of a media guidance application to aggregate information from one or more sources and one or more mediums. For example, the media guidance application may automatically collect information based on attributes associated with information of a particular type. Specifically, the media guidance application may determine based on comparison with verified training data that one source or medium typically associates information of a particular type, for example, “Actor,” with one or more path attributes, for example, a location in a directory structure. The media guidance application may then search the source or medium for the one or more path attributes. Upon detecting the one or more path attributes, the media guidance application may designate any sub-set of information associated with the one or more path attributes as a particular type of information.
