통계 언어학에 기반한 조사 ‘와’의 결합 특징 연구

Abstract

This study employs statistical linguistic methods to conduct a fine-grained analysis of the combinatorial characteristics of the Korean particle ‘wa’ (와) in its two primary grammatical roles: the adverbial case particle and the conjunctive particle. Based on a large-scale written corpus, the research first conducts a frequency analysis of the morpheme categories that precede and follow ‘wa’. To move beyond raw frequency, the study then applies Mutual Information (MI) to quantitatively measure the strength of association between ‘wa’ and its adjacent morphemes. Furthermore, the Chi-square test is utilized to evaluate the statistical significance of these collocational patterns, distinguishing meaningful linguistic preferences from random co-occurrence. The analysis systematically compares the combinatorial profiles of the two functions based on these quantitative measures.
