1. A computer-implemented method for travelogue-based contextual map generation, the computer-implemented method comprising performing computer-implemented operations for: identifying, by a computing device, one or more locations mentioned in a Web page travelogue for a particular location; causing a map to be generated and displayed, by the computing device, in conjunction with a display of the Web page travelogue, the map encompassing the identified locations; generating, by the computing device, co-occurrence values for the one or more locations by identifying a number of times a pair of first and second locations are mentioned within a universe of travelogues associated with the particular location; identifying, by the computing device, at least one other location based on the co-occurrence values; and causing the map, by the computing device, to encompass the at least one other location.
