음운론적 복잡도와 적합도의 상관관계에 대하여

This paper explores ways of quantifying wellformedness based on Information Theoretic concepts such as Phonological Complexity (PC). Goldsmith (2002) proposed that as the wellformedness of a representation increases, PC, which is computed from the probabilities of component unigrams and bigrams of words, becomes lower. The purpose of this paper is to propose the revised PC which reflect the effect of syllable numbers in Korean verb stems and words, and examine whether the correlation of phonological markedness between the revised PC and the wellformedness holds for glide formation in Korean, which has been thought to occur to avoid marked VV sequences. The statistical analyses of the hiatus and glide formation show that not only wellformedness but also revised PC significantly differ. Furthermore, Pearson correlation test of the hiatus and glide formation can provide significant correlation between the revised PC and the phonological wellformedness. Pearson correlation test of 32 stems which have one or two syllable reveals a statistical significant negative correlation coefficient between the revised PC and the phonological wellformedness.
