The present invention relates to a method for detecting grammatical errors, an error detection device for the same and a computer-readable recording medium having the method recorded thereon, wherein the frequency of morpheme sequences which are the same as a forward morpheme sequence and a reverse morpheme sequence with respect to a written sentence are confirmed and errors on the basis of a high frequency are detected. An example-based technique in the natural language processing field is an existing technique used in machine translation, and a method for extracting translation knowledge with many pairs of original sentences and translated sentences as examples and performing automatic translation on the basis of the extracted translation knowledge is applied. Therefore, since the example-based method applied in machine translation uses a large amount of examples, there is an advantage of using the example-based method as a high-quality translation function. Particularly, since language naturally changes according to the time and location rather than rules, patterns frequently used by people can be easily applied even without continuously generating complicated rules.
