2. The computer-implemented method of claim 1 , further comprising computing conditional probabilities of occurrence of words in geographic queries based at least in part on the geographic language model.
2. The computer-implemented method of claim 1 , further comprising computing conditional probabilities of occurrence of words in geographic queries based at least in part on the geographic language model. 3. The computer-implemented method of claim 2 , further comprising: receiving a geographic query from a user; generating an alternative geographic query that is a variant of the received geographic query; computing a probability of occurrence of the received geographic query and a probability of occurrence of the alternative geographic query based at least in part on the computed conditional probabilities; and responsive to the probability of occurrence of the alternative geographic query being higher than the probability of occurrence of the received geographic query, providing the alternative geographic query to the user as an alternative query.
