9. A computer-implemented method comprising: identifying a travelogue for location-related mining; decomposing the travelogue into a plurality of portions of the travelogue to identify a particular location and a context term, the context term characterizing the particular location without co-occurring with a plurality of locations; filtering out one or more noisy context terms that do not characterize the particular location and co-occur with a plurality of locations from at least one portion of the travelogue; extracting the particular location from the portion of the travelogue as decomposed; mining the context term which characterizes the location from the portion of the travelogue as decomposed; creating a geo-snippet comprising the particular location and the context term which characterizes the particular location; obtaining a geographic relevance score corresponding to the geo-snippet; obtaining a semantic relevance score corresponding to the geo-snippet; and computing, by a processor, a snippet score corresponding to the geo-snippet based at least in part on the geographic relevance score and the semantic relevance score.
11. A computer-implemented method as recited in claim 9 , further comprising building at least one tag from information comprising one or both of the location or the context term which characterizes the location.
