  • program code which examines the text data to identify the homograph within the text data and to extract words surrounding the identified homograph in the text data;

    program code responsive to the identified homograph which identifies the possible parts of speech that the identified homograph can assume;

    program code responsive to the possible parts of speech that the identified homograph can assume that obtains a set of rules, each rule based on a pair of possible parts of speech of the identified homograph and a word order and position of one of the surrounding words;

    program code which sequentially applies the rules in the obtained rule set until a rule is satisfied to determine a part of speech for the homograph in the text data; and
