1. A method of decoding input, the method comprising:

  • identifying possible sequences of words from the input;

    using a class-based language model and a class entity dictionary to select one of the possible sequences of words as an output sequence, the class entity dictionary providing the probability of an entity given a class;

    receiving modifications made to the output sequence by receiving a modified entity that represents a modification of a decoded entity in the ouput sequence; and

    using the modifications to change the class entity dictionary by adding the modified entity to the class entity dictionary and estimating a probability for the modified entity given the class to which the entity is added based on an n-gram probability associated with the decoded entity and an n-gram probability associated with the class to which the modified entity is added.
