APPARATUS FOR GRAMMATICAL ERROR CORRECTION AND METHOD FOR GRAMMATICAL ERROR CORRECTION USING THE SAME

摘要

The present invention relates to a system for correcting grammatical errors and a method for correcting grammatical errors using the same. More particularly, the system for correcting grammatical errors comprises: a learning unit for acquiring a plurality of contextual qualities according to language characteristics from a plurality of corpuses and generating a first learning classification model and a second learning classification model which are standards for diagnosing grammatical errors from the contextual qualities; and an execution unit for predicting grammatical errors for a corpus inputted by a learner using the first learning classification model, predicting grammatical errors using a first prediction result of the grammatical errors and the second learning classification model, and correcting the grammatical errors, wherein the second learning classification model is generated by a repeated learning technique using the contextual qualities extracted from the corpuses, based on the first prediction result.
