1. A method in a computing device for identifying a location associated with a document, the method comprising: providing a collection of documents of words, each document associated with a location; generating collection level parameters for a latent Dirichlet allocation style model for the collection of documents that based on latent topics and the location of each document, the collection level parameters indicating a probability that a document in the collection relates to each latent topic, a probability that each word of the collection relates to each latent topic, and a probability that each location of the collection relates to each latent topic; and estimating, using the collection level parameters, a probability that a location is associated with the document based on an aggregation of, for each topic, the conditional probability of the location given the topic and the conditional probability of the topic given the document.
