Abstract

The present invention relates to error detection for automatically evaluating a sentence and provides an automatic sentence evaluation device using a shallow parser to automatically evaluate a sentence, whereby a simple grammatical error and an error in sentence structure analysis are detected by generating a string of parts of speech using n-gram for a composed input sentence and parsing the generated string of parts of speech on the basis of a rule (shallow parsing) defined according to a connective relationship between adjacent parts of speech, and a corrected draft is proposed for the detected errors to thereby increase accuracy of sentence evaluation, and an error detection apparatus and method for the same.

Description

technical field [0001] This disclosure relates to error detection for automatically evaluating sentence composition, and more particularly to an apparatus and method for automatically evaluating sentence composition and an error detection apparatus for this purpose, which segments a composed input sentence into morphemes, Parts of speech are tagged to the segmented morphemes, simple grammatical English writing errors are detected for each part of speech string, and they are syntactically analyzed based on rules defined by the connection relations of parts of speech adjacent to each other to improve composition evaluation the accuracy. Background technique [0002] Recently, the Korean SAT and Enterprise Grading assessments have been changed to assessments based on actual spoken and written English performance. [0003] Namely, the Ministry of Education has developed NEAT (National English Proficiency Test, which is an Internet-based assessment of listening, reading comprehe...
