  • manually defining a set of classes for words/phrases, each class being associated with a class-tag;

    replacing words of domain-related rules with corresponding class-tags to generate class-based domain-related rules;

    generating a class-based rule net using the class-based domain-related rules;

    obtaining a class-based statistical representation from the class-based rule net; and

    combining the class-based statistical representation with a class-based statistical representation from a statistical language model to generate a final language model.
