About the Lab
Professor Gwang-Yoon Ko's research lab specializes in corpus-based applied linguistics, focusing on the authenticity, continuity, and pedagogical appropriateness of English language materials in Korean educational and media contexts. The lab investigates textbook language, standardized test vocabulary, and native-like proficiency in Korean-English contexts, with an emphasis on function words, lexical distribution, and corpus-driven evaluation. A central aim is to develop a distinct, internationally competitive model of Korean-style English linguistics grounded in empirical data.

15This study is a corpus-based analysis of Korean middle school English textbooks and it aims to verify whether their English vocabulary is presented with sufficient educational continuity by examining the five most widely used series of middle school English textbooks (7th-9th grades). In particular, the study analyzes TTR (type-token ratio), the distribution of new words, average sentence length, and other relevant factors in the 15 middle school English textbooks in order to evaluate the contin
Despite the considerably growing interest in corpus linguistics and the use of authentic language data among Korean (English) linguists, only a few seem to be confident about the use of corpora and corpus tools in their linguistic research. This paper takes a close look at (more powerful) WordSmith Tools 4.0 and (more user-friendly) MonoConc Pro 2.2, two of the most useful and readily accessible software packages for corpus-based investigations and linguistic analyses, with an aim to compare the
This study is a corpus-based analysis of the English vocabulary used in the English exams of the College Scholastic Ability Test (CSAT) and its two analogous tests (i.e., the Mock CSAT and the Achievement Test), and it aims to determine the vocabulary levels of the three types of English exams and evaluate their appropriateness as tests to measure prospective college students' English proficiency for higher education, an issue left mostly untouched in all previous studies. To achieve this goal,
English linguistics of Korea, despite its considerable development and growth for the last 50 years, has continued to lag behind that of not only the US and the UK but also many European countries and even Japan as well. The current state of English linguistics of Korea seems to be closely related, above all, to our lack of the native speaker’s intuition about English and the failure in developing a successful model of Korean-style English linguistics which enables us to overcome our weaknesses
The language of English newspapers in Korea may seem grammatically perfect, partially due to the editing and correction of English-speaking proofreaders, but still shows some interesting ‘non-nativeness’ of many different kinds. This paper is a corpus-based study of the language of English newspapers in Korea and its main goal is to show what is behind the ‘non-nativeness’ of the English language found in Korean English news. The discussion of this study is mainly based on the analyses of high-f
This study is a corpus-based analysis of textbook English and it attempts to evaluate the authenticity of the (English) language used in Korean English textbooks by examining the uses of high-frequency function words in the two corpora, KHERC (based on seven Korean high school English reading textbooks) and Frown Corpus. The results of this study indicate that the function words used in Korean English textbooks often do not fully represent their typical uses and distributions observed in natural
There have been a great many studies of English textbooks in Korea, but virtually none of them have considered the authenticity of English used in the textbooks though the presence of some ungrammatical or odd English sentences in the textbooks has occasionally been noted. The present study, an effort to fill this gap, is a corpus-based analysis of Korean English textbooks and aims to demonstrate the authenticity of textbook English by examining the five most widely used series of middle school
The so-called light verbs in English have very often been discussed both in traditional grammar and generative linguistics. The variation shown in these verbs, especially that of have a NOUN vs. take a NOUN, however, has only been very briefly mentioned, with few previous studies having provided an extensive empirical analysis of the variation, thereby letting the phenomenon remain mostly a matter of preference in British or American English. This study investigates the variation between the lig
This article investigates corpus-based English vocabulary studies carried out in Korea for the last ten years in an attempt to discuss their current status and limitations and suggest ideas for possible solutions and future directions in this research area. To attain this research goal, the present study examines a total of 40 research articles and theses that mainly aim to present an analysis of overall vocabulary level of texts. The results indicate that many of these studies need to compile a
Although the alternation of different from, different than, and different to has been among the most talked-about linguistic variations in English, few previous studies have provided a thorough empirical analysis of the alternation, thereby letting the issue remain mostly a matter of which choice is correct or more appropriate. This study discusses the use of the three English prepositions occurring after different on the basis of the relevant data from seven English corpora. The results indicat
본 연구는 번역된 텍스트들에 전형적으로 나타나는 언어적 특성들인 번역 보편소(translation universals)에 관한 코퍼스 기반 연구이다. 지금까지의 번역 보편소 연구는언어계통상 서로 밀접한 관련이 있는 영어와 다른 유럽어 사이의 번역에 집중되어왔으며, 다른 한편으로 주로 문학 장르의 분석에 치중되어 있다는 아쉬움을 지닌다. 본 연구에서는 관련 연구가 지닌 이러한 두 가지 주요 문제점을 보완하고자 하는 노력의일환으로 한국어를 원문으로 하는 영어 번역 가운데 비문학 장르인 신문언어 텍스트를분석대상으로 선택하였다. 먼저, 번역된 신문영어 텍스트와 비번역 신문영어 텍스트를정해진 기준에 따라 수집하여 번역과 비번역 영어(translated and non-translated English)로 구성된 대응코퍼스(comparable corpora)를 구축하였다. 이렇게 구축된 대응코퍼스를 바탕으로 기존 문헌에서 논의된 번역 보편소 가설 가운데 가장 대표적인단순화(simplificati
English newspapers, along with the increasing attention to (E)NIE ((English) newspaper in education), have been one of the most recommended resources for English study among Korean students and teachers, resulting in many studies dealing with the use of English newspapers in and outside classroom. Despite considerable contribution of these studies, however, few of them have provided a systematic analysis of English newspaper vocabulary, thereby making it difficult for teachers and students to pr
Keyword calculation for a text in corpus linguistics is usually made through the comparison of the word list of the text with the word list of a reference corpus (RC). For this very reason, its results are highly likely to be influenced by one's choice of the RC, thereby making it worthwhile to examine the relationship between the RC and resulting keyword results. This paper is a quantitative study of the effects that the size and composition of the RC can have on the results of keyword calculat
Goh, Gwang-Yoon, Lee, Younghee (Cheri) & Kim, Dongyoung. 2016. A Corpus-based Study of Translation Universals in Abstracts: Centered on the Discrepancies between Translated and Non- Translated Language. Korean Journal of English Language and Linguistics 16-4, 819-849. This article argues that the translated English texts hold particular linguistic properties distinctive from the non-translated English texts on a substantial level. By compiling the purpose-end comparable corpora of translated and
With the importance of vocabulary knowledge in language development more fully appreciated, a great deal of studies have been done on incidental vocabulary learning through (extensive) reading. Yet, few studies have attempted to analyze how the size of incidentally learnable vocabulary changes as the amount of reading increases, a question which, if answered properly, can greatly help language learners and their teachers to stay motivated in the long process of learning a foreign language by let
