심리학적 한국어 분석 프로그램을 사용한 언어분석 비교

Abstract

In order to assess the reliability and distinguishing features of the Korean Psychological Language Analysis System (PLAS), a comparative analysis was conducted with KLIWC, a widely used language analysis program in previous research. A diverse range of text genres, including newspaper articles, editorials, non-experimental papers, comments, novels, and essays, were collected for analysis using both PLAS and KLIWC. The comparison of the categories commonly classified by both programs demonstrated a strong correlation, supporting the reliability of PLAS language analysis. Additionally, the analysis of the correlation between the categories of KLIWC and the more detailed categories of PLAS revealed a high correlation, indicating the distinctiveness of PLAS in capturing specific variables. Furthermore, a comparison was conducted between newspaper articles, which aim to convey information, and newspaper editorials, which aim to present responsible arguments on major domestic and international issues, in order to analyze the differences between informative and opinionated texts using PLAS. The analysis revealed significant differences between newspaper editorials and articles in PLAS-specific categories such as status, sensory expression, and tense pre-final endings. Through a comparison of unique categories analyzed only by PLAS, the distinctions between newspaper editorials and articles became more evident. Finally, an in-depth discussion on the characteristics and limitations of PLAS was conducted.
