Results of the study indicate that the probability-based tagger outperforms the rule-based tagger, and that the probability-based tagger yields an accuracy comparable to that achieved when the tagger is used to tag English native speakers' texts. It is also found that the rule-based tagger does not perform stably, and that its accuracy is often affected by the quality of learner language.
