1. A method of evaluating a sequence of characters received by one or more computing devices to determine the presence of a natural language word in the received sequence, the method comprising:

  • finding a subsequence of alphabetical characters in the received sequence of characters, wherein the received sequence comprises both alphabetical and non-alphabetic characters, and wherein the subsequence corresponds to alphabetical characters occurring between the non-alphabetic characters in the received sequence;

    calculating a probability that the subsequence is a natural language word using a statistical model of a natural language; and

    determining if the subsequence is a natural language word based on the probability;

    wherein the finding, calculating, and determining steps are performed on the one or more computing devices.
