Claim 10:
11. A system for recognizing an event in a geographic region based on a deviation from a baseline frequency of domain-specific ontological terms, the system comprising:
non-transitory storage media configured to store documents and an ontology that includes ontological terms related to a domain of interest; and
a server configured to:
analyze the documents to identify a baseline frequency of the ontological terms;
identify 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 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;
identify a deviation from the baseline frequency of the ontological terms by comparing the frequency of the ontological terms in the additional documents to the baseline frequency of the ontological terms; and
identify a geographic region of interest 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.
