The purpose of this study is to examine how cohesion features can be used to distinguish between essays written by Korean and NS college students. A total of 800 essays from the ICNALE (International Corpus Network of Asian Learners of English) corpus were analyzed using the newly-developed automated analysis of cohesion program, TAACO (the Tool for the Automatic Analysis of Cohesion). In order to examine whether there are statistically significant differences between NS and Korean students, a multivariate analysis of variance (MANOVA) was conducted. The multivariate test result showed that the combined cohesion indices were significantly affected by L1, indicating that Korean and NS students differed in terms of various cohesion indices. A stepwise discriminant function analysis was also carried out to characterize the nature of cohesion differences in essays between NS and Korean students. The best two predictors for distinguishing between Korean students’ essays and NS students’ essays are the overlap of function words and the use of demonstratives. Overall, NS students produced a more cohesive writing than Korean students in that they employed overlapping words, demonstratives, and lexical subordinators as a way to connect ideas across sentences. Implications of this study for English writing pedagogy are discussed.
