Abstract
An error detection system for automatically evaluating writing includes: an example construction apparatus to collect example sentences including various literary styles, to break up the collected example sentences in units of morphemes, and to construct the example sentences in an example-based index database (DB); and an error detection apparatus to break up an input sentence in units of morphemes, to generate one or more morpheme sequences bound in arbitrary window sizes based on one or more of morphemes of the broken-up input sentence, to search the example-based index DB for each of the generated morpheme sequences, and to detect an error according to a frequency at which said each morpheme is arranged in a corresponding morpheme sequence among morpheme sequences searched for through the example-based index DB.
