1. A system comprising: a processor; a data bus coupled to the processor; and a computer-usable medium embodying computer program code, the computer-usable medium being coupled to the data bus, the computer program code used for refining cognitive insights using cognitive graph vectors and comprising instructions executable by the processor and configured for: storing travel-related data from a plurality of data sources within a cognitive graph; associating a first set of the travel-related data within the cognitive graph with a first travel-related cognitive graph vector of a plurality of travel-related cognitive graph vectors; associating a second set of the travel-related data within the cognitive graph with a second travel-related cognitive graph vector of the plurality of travel-related cognitive graph vectors; processing the travel-related data from the plurality of data sources to provide travel-related cognitive insights; and refining the travel-related cognitive insights based upon a limitation relating to one of the plurality of travel-related cognitive graph vectors.
