Geolocating social media

A system comprising:

• one or more processers;
• one or more computer readable media;
• a knowledge base creation and updating application stored on at least one of the one or more computer readable media that, when executed by at least one of the one or more processors, directs the at least one of the one or more processors to
• search at least one database comprising social media data having geo-coordinates and at least one associated tag;
• create location-based data clusters of the social media data using the geo-coordinates,
• extract at least one tag for each location-based cluster from the at least one associated tag of the social media data in that cluster, and
• store the at least one tag in association with geo-coordinates for that cluster in a knowledge base.

A system comprising:

• one or more computer readable media;
• instructions stored on at least one of the one or more computer readable media that, when executed by a processor, directs the processor to:
• extract information from textual content associated with a non-geolocated social media data item,
• search a knowledge base to determine at least one geocode to which the information from the textual content relates, and
• append an estimated geocode to the non-geolocated social media data item according to the at least one geocode to which the information from the textual content relates.
