1. A computer-readable medium having computer executable instructions encoded thereon, the computer executable instructions executed by a processor to perform location-related mining operations, the operations comprising: identifying a particular travelogue; decomposing the particular travelogue by identifying at least two non-overlapping segments of the particular travelogue, each segment including a representation of at least one location; representing a collection of travelogues with a term-document matrix, the collection of travelogues comprising the particular travelogue, and each word of the particular travelogue representing: a location, a local topic, and a term in a sequence; or a global topic and a term in a sequence; using a probabilistic topic model, decomposing the term-document matrix into one or more matrices comprising: a term-local topic matrix; a local topic-location matrix; or a location-document matrix; and representing a particular location by a multinomial distribution over local topics while associating a document with a multinomial distribution over global topics.
