Base Claim:
1. A method comprising: selecting, by a processor, a toponym-place pair of a target document that includes a plurality of toponyms corresponding to a plurality of toponym-place pairs, wherein the place of each toponym-place pair identifies a geographical location or region designated by the corresponding toponym; and for the selected toponym-place pair, the method further comprises: generating, by the processor, a confidence value, wherein the confidence value presents a confidence that the toponym of the selected toponym-place pair refers to the place of the selected toponym-place pair, and wherein the confidence value is pre-computed and derived from a statistical observation about a plurality of documents; determining if another toponym is present within the target document that has an associated place that is geographically related to the place referred to by the selected toponym-place pair; and if the another toponym is present within the target document that has an associated place that is geographically related to the place referred to by the selected toponym-place pair, boosting the generated confidence value for the selected toponym-place pair for the target document; and ranking the target document based on the boosted confidence value.
