The Impact of Subordination Type and Finiteness on Second Language Development in Timed Impromptu Writing: An NLP-Based Analysis Using the Subordination Sophistication Analyzer

Peer reviewed

Direct link

Haerim Hwang – Written Communication, 2025

The use of subordination enables language users to achieve syntactic efficiency by allowing them to connect ideas in temporal/logical relation. Although the importance of subordination has been recognized in previous research on second language (L2) writing, it has been typically assessed with global indices that measure overall ratio of…

Korean Syntactic Complexity Analyzer (KOSCA): An NLP Application for the Analysis of Syntactic Complexity in Second Language Production

Peer reviewed

Direct link

Haerim Hwang; Hyunwoo Kim – Language Testing, 2024

Given the lack of computational tools available for assessing second language (L2) production in Korean, this study introduces a novel automated tool called the Korean Syntactic Complexity Analyzer (KOSCA) for measuring syntactic complexity in L2 Korean production. As an open-source graphic user interface (GUI) developed in Python, KOSCA provides…
