    parsing an utterance to identify syntactic relationships amongst words in the utterance;

    creating sets of words from the utterance based on the syntactic relationships;

    mapping each set of the sets of words to a respective candidate intent value to produce a list of candidate intent values for the utterance;

    ranking the candidate intent values in the list based on usage of the sets of words in previously received utterances;

    selecting, from the list, a candidate intent value as being representative of an intent of the utterance;

    detecting that the selected candidate intent value maps to multiple possible labels in a label listing, an entry in the label listing indicating that the selected candidate intent value maps to the multiple possible labels, the multiple possible labels including a majority label representing a first classification and a minority label representing a second classification;

    selecting the majority label;

    assigning the selected majority label to the utterance to indicate that the utterance falls into the first classification, the selected majority label representative of a dominant subject matter likely intended by the utterance.
