Claim 0:
1. An automated method for recognizing an event in a geographic region based on a deviation from a baseline frequency of domain-specific ontological terms, the method comprising:
receiving an ontology including ontological terms related to a domain of interest;
receiving documents by a server;
analyzing the documents, by the server, to identify a baseline frequency of the ontological terms;
identifying a relevant geographic region for each of at least some of the documents, by the server, by determining whether the document identifies one or more named places in the geographic region of interest or is from or focused on the relevant geographic region;
analyzing additional documents, by the server, to identify a frequency of the ontological terms in the additional documents and a relevant geographic region for each of at least some of the additional documents;
identifying a deviation from the baseline frequency of the ontological terms, by the server, by comparing the frequency of the ontological terms in the additional documents to the baseline frequency of the ontological terms; and
identifying a geographic region of interest, by the server, by identifying the relevant geographic region of documents wherein the frequency of the ontological terms exceeds the baseline frequency of the ontological terms by a predetermined threshold.
