Patent ID: 8572076

Claim:
A computer-implemented method for location context mining within document text, the computer-implemented method comprising performing computer-implemented operations for: receiving one or more documents; identifying, by a computing device, location words within the documents; identifying, by the computing device, candidate location context words within the documents, the candidate location context words being non-geographic words located within a specified word count of the location words with the documents, the candidate location context words being associated with the identified location words within the documents, where a set of all possible candidate location context words c i,j for each location word in a list of location words X i,j being defined as: c i , j = { w i , j k ∈ D i ❘ / ( X ij , w ij k ) ≤ T } , where w i,j k is the k th word in a document D i , the function /( . . . ) being a measure of a distance between the two words, and T being a predefined threshold; establishing, by the computing device, a set of possible pairings between the location words and the candidate location context words; and generating, by the computing device, a score for each pairing comprising a term frequency inverse document frequency (TF-IDF) score.
