한국어 분석 도구를 활용한 국어교과서 텍스트의 장르 비교 분석

Abstract

This study aimed to investigate the characteristics of three different genres, including argumentative, expository, and narrative texts that were selected from high school Korean textbooks revised by the 2015 National Curriculum with Auto-Kohesion, a Korean text analysis tool. The indices used for the current study included basic measures (the number of words, the number of sentences, the average sentence length, the average word length), word frequency (word frequency for contents words and all words), lexical diversity (type-token ratio for content words), personal pronouns (the first person pronouns, the second person pronouns, the third person pronouns, all pronouns), connectives (causal, additive, and all connectives), syntactic complexity (the ratio of modifiers, the ratio of constituents), and reference cohesion measures. The analysis demonstrated that the argumentative and expository texts were not significantly different in all measures. However, the differences between the two genres versus narratives were substantial; a greater use of personal pronouns and lower frequency words as well as more words and sentences was identified in the narrative texts, whereas the argumentative and expository texts included the higher text cohesion and the sentence constituent ratio along with the longer average words and sentences. The argumentative texts have been shown to include more personal pronouns than the other two genres. The current study provides some implications for designing Korean textbooks and analyzing the characteristics of different genres.
