This paper is a corpus-based study of Maritime English. Maritime English is an area of English for Specific Purposes (ESP) requiring special attention. Although grammar is important, vocabulary is the key difference among varieties of English. The purpose of this paper is to explore some vocabulary features of Maritime English extracted from the Maritime English Corpus (MECO) of Hong and Jhang (2010), referenced against the LOB or the BNC. This corpus-based lexical analysis has been made by compiling both a word-list of high frequencies in the MECO and a keyword-list referenced against the LOB with a WordSmith Tools 5.0 program. We also use a Perl program to extract noun compounds, to set up vocabulary lists, and to suggest how many words should be learned by beginning students (80% cumulative frequency rate) and by advanced students (90% cumulative frequency rate). We explore the distribution of parts of speech as content versus function words and point out significant differences between Maritime English and General English.

An Overview of Korean Sign Language

Jhang Se-Eun(장세은) 새한영어영문학회 2006 새한영어영문학 Vol.48 No.1

본 연구의 목적은 한국수화언어의 개관을 살펴보는 것이다. 첫 번째로, 한국에서의 수화언어가 해방전후에서 최근까지 어떻게 이해되고 있는지 시대 순으로 살펴본다. 두 번째로, 한국수화언어의 언어적인 특성을 연구한 주요논문 (S. Kim 1983; Suk 1989; Hwang 1994; lang 1995; Ch. Kim 1998; Jhang 1997, 1999a, 1999b; Hong 2001)을 중심으로 간략하게 살펴본다. 세 번째로, 수화언어의 습득과정과 관련된 주된 논쟁 (Hwang 1994; Ahn 1997; Na & Kang 2001: Jun 2001; Won 2002)을 살펴본다. 네 번째로, 구화중심(Chun 1998)의 의사소통 수단과 한국표준수화(Jung 2002) 또는 한국수화언어 (Choi & Ahn 2003; Jhang 2003)로서의 의사소통 수단과 한글작문과 독해능력간의 관련성에 대한 논쟁을 소개한다. 마지막으로, 미래의 한국수화언어의 언어학적인 연구는 제2언어로서의 한국어와 제1언어로서의 한국수화언어에 기초를 둔 이중언어-이중문화 접근 관점에서 한국수화언어를 연구하여야 하는 함을 제안한다. So far, I have offered an overview of KSL. The first section presented a history of sign language in Korea. Here, it was pointed out that KSL may belong to the JSL Family owing to the great influence of JSL during the 35 years of the colonization. In addition, it was examined that most educators and educational administrators have paid much attention to KSDSL because they believe, without any evidence, that it would improve Korean literacy. The second section was concerned with investigation of internal organization of signs and morpho-syntactic properties on the basis of distinctive research on linguistic properties of KSL. The third section was given a brief review of the research on the processing of the acquisition of KSL. Here, it was stressed that early exposure to both KSL and Korean provides the strongest support for the acquisition of literacy skills, It was pointed out that we should need a preliminary study regarding the processing of KSL acquisition for deaf children at the early stages. The fourth section presented the debate on the issue of the language of instruction in the classrooms with regard to Korean literacy and a mode of communication such as oralism, Sign Korean, or KSL. We first examined that the change from oralism to Signed Korean began in the late 1980s. The fourth section pointed out that very recent research showed that greater KSL proficiency contributes positively to the improvement in literacy skills of Korean deaf students. Finally, I have presented five kinds of direction for further research on KSL: (ⅰ) a bilingual and bicultural approach based on KSL as the primary language and Korean as a second language (ⅱ) an intensive KSL immersion program just like bilingual education for hearing minority-language students (ⅲ) the training up of teachers who are bilingual and bicultural (ⅳ) both KSL learning for hearing people and tests for interpreters (ⅴ) the production of deaf linguists for KSL analysis and research.

○ The purpose of this study is to discuss sentiment analysis of major characters in Shakespeare`s tragedy plays using dialogue corpora, comparing two types of word-lists for sentiment analysis: AFINN(Nielsen 2011) and VADER (Hutto and Gilbert 2014). ○ First, (i) we try to investigate important tone patterns, using line graphs as time visualization, which both polarity(positive/negative) and intensity (strength) of all characters` sentiment valence sum in each of his 10 tragedy plays may show in order to uncover different types of Shakespeare`s tragedy. ○ In order to do, this, this study focuses on the comparison of sentiment analysis of Shakespeare`s love tragedies (Othello, Anthony and Cleopatra, and Romeo and Juliet) and love comedies(A Midsummer Night`s Dream, The Two Gentlemen of Verona and As You Like it), which Archer, Culpeper and Rayson (2005) classified. ○ Second, (ii) we will discuss some features of sentiment changes between characters within an act and across acts in the four tragedies through the development dispersion of emotional relationship. We also use bar graphs as time visualization, which means that knowing who is speaking to whom allows the flow of positive and negative sentiment valence sum to be tracked. ○ Finally, (iii) this study also attempts to visualize network structures connecting major characters in Shakespeare`s connecting major characters in Shakespeare`s tragedy plays to easily figure out their detailed emotion relationship, representing relation visualization.

키클러스터 분석을 통한 학술목적영어 코퍼스의 어휘다발 특성 연구

장세은 ( Se Eun Jhang ),이성민 ( Sung Min Sung ) 대한언어학회 2012 언어학 Vol.20 No.4

This study is to investigate structural and functional features of English lexical bundles in the Biomed Corpus as a Life Science Corpus through key clusters analyses. Previous studies have identified lexical bundles using their different criteria, but in this study lexical bundles were extracted and identified in a limited number of frequent phrases in comparison to a reference corpus using key clusters analyses. Structural and functional classification of lexical bundles was made following recent work by corpus linguists such as Biber and Barbieri. We found that the lexical bundles that we dealt with represent both positive and negative keyness in value in the list of key clusters, just like keywords analyses. The article examines and discusses the distribution of the frequence category of lexical bundles, the ratio of type and token of nouns in the structures of ``the+Noun+of the`` and ``in the+Noun+of``, various types of passive constructions, and epistemic stance expressions standing out in functional distribution of lexical bundles in comparison to a reference corpus.

키워드 네트워크 분석을 통한 세계 해운경제의 연구 주제와 동향에 대한 연구

장세은(Jhang, Se-Eun),이수호(Lee, Su-Ho) 한국항만경제학회 2016 韓國港灣經濟學會誌 Vol.32 No.1

본 연구에서는 세계 해운경제관련 국제저널에 게재된 논문을 대상으로 5년 주기의 연도 기간별로 2000년∼2004년, 2005년∼2009년, 2010년∼2014년 세 단계로 나누고 저자키워드를 추출하여 네트워크 분석방법인 연결중심성과 매개중심성 방법론을 활용하여 세계 해운경제의 연구동향을 양적인 관점에서 살펴본다. 빈도로 추출한 본 연구의 자료는 Zipf’s의 법칙을 따르고 있으며, 키워드 노드들이 멱함수 분포를 가지므로 해운경제 키워드가 네트워크분석에 적합하다는 것을 보여주었다. 연도시기별로 공유되는 키워드 분석에 설명력을 더해 주기 위하여 Delta-C 알고리즘을 만들어서 시간에 따른 키워드의 변화 경향을 설명하고자 하였다. 본 연구의 결과는 다음과 같다. 해운경제 키워드를 세 개의 연도시기별로 분석한 결과 두 개의 서로 다른 패턴을 발견하였다. 첫 번째 패턴은 세 개의 모든 기간에 공유되는 키워드이고 두 번째 패턴은 두 개 시기에 연속적으로 혹은 불연속적으로 나타나는 키워드였다. 모든 시기에 연속적으로 사용된 키워드는 연결중심성 값이 불규칙하게 변화하는 양상을 보인다. 주기가 연속인 경우는 세 가지이다. 첫 번째 경우는 2000년∼2004년과 2005년∼2009년 연속으로 걸쳐서 사용된 키워드의 특징은 처음에 사용된 키워드의 중심성이 다음 연도기간에 사용될 때에는 낮은 연결중심성을 가졌다. 두 번째 경우는 2005년∼2009년과 2010년∼2014년 연속으로 걸쳐서 나타난 키워드에서는 후반기에 사용된 키워드가 더 높은 연결중심성을 보였다. 세 번째 경우는 2000년∼2004년과 2010년∼2014년의 불연속으로 나타난 경우인데 과거에 사용된 모든 키워드의 연결중심성은 가장 최근에는 모두가 낮은 연결중심성 값을 가졌다. 매개중심성을 사용한 연도시기별 키워드분석결과 이 방법은 연결중심성에 비해서 더 많은 비공유 키워드를 상위에 나타났다. 이러한 연구의 결과의 의의는 네트워크분석을 통하여 향후 연구동향 예측의 기초 자료로 활용할 수 있다는 점이다. 즉, 연결중심성은 연도 기간별 주요 연구주제를 파악할 수 있는데 도움을 줄 수 있고 매개중심성은 특정기간에 등장하는 특이한 주제 파악에 도움이 된다는 것이다. This study identifies themes and trends in maritime economics and logistics by examining 303 papers published in international journals from 2000 to 2014 using keyword network analysis. Network analysis can be used because the collected data follow Zipf"s law and the power law. Utilizing the degree centrality and betweenness centrality, we find the important keywords in each five year period and determine the importance of shared keywords. To further explain keyword centralities, we invented a Delta-C algorithm to show the trends of keywords over time. We found that degree centrality is useful for identifying important research themes in each period because it is mainly concerned with the number of connections. On the other hands, betweenness centrality is useful to determine the unique themes that emerge in each of the specific periods.

고등학교 해사영어 교과서와 해기사 해사영어시험 간의 상관관계 분석

장세은(Jhang, Se-Eun),이성민(Lee, Sung-Min) 새한영어영문학회 2014 새한영어영문학 Vol.56 No.2

We compared the Korean Maritime Officer Certification Tests (MOCT) and two textbook corpora with some vocabulary covering 80% and 90% cumulative frequency of the Maritime English Corpus (MECO) to see the relationships between correlation coefficients using both quantitative and qualitative analyses. We tried to explain these differences and similarities through frequency ratio. We found that the MOCT showed a much lower correlation coefficient score with these MECO vocabulary words than the Busan Metropolitan Education Office Textbook (BUSAN) and the Ministry of Education, Science and Technology Textbook (MEST) did. The BUSAN and the MEST showed very high correlation coefficients. On the other hand, the MEST showed more similarity with the MOCT than with the BUSAN, though the difference is very small. However, when we observed the top 30 content words extracted from the MOCT for qualitative analysis of correlation coefficients, we found that the BUSAN seems to show more similarity with the MOCT than the MEST does, in contrast to their relationships between correlation coefficients using quantitative analysis.

A Corpus-based Analysis of English Abstracts of Korean Scholarly Articles

Jhang, Se-Eun(장세은),Hong, Shin-Chul(홍신철) 새한영어영문학회 2012 새한영어영문학 Vol.54 No.4

This paper reports on a corpus-based study of English for Academic Purposes (EAP). It investigates linguistic characteristics of English abstracts written by Korean scholars in the fields of English Literature and of English Linguistics in order to find lexico-grammatical patterns used by native and non-native English scholars specializing in English Literature and English Linguistics. The paper hopes to offer suggestions on suitable academic English pedagogical techniques, especially for English writing. In our study we compiled two English abstracts corpora from journals of English language and literature and journals of English linguistics from English-speaking countries and from Korea for the years 2000 to 2011: Anglophonic Corpus and Korean Corpus. Each corpus further yielded two subcorpora: native and non-native English literature corpora and native and non-native English linguistics corpora. Unlike previous studies focusing more or less on abstracts of native scholars, in this study abstracts of non-native scholars are compared to those of native scholars in the areas of English literature and English linguistics. This study contrastively analyzes abstracts in academic research articles in terms of two aspects: (i) native/non-native speakers’ distinctive use of language and (ii) linguistic features of abstracts as a genre. In particular, four types of methodologies (statistics, wordlists, keywordlists, and key clusters) often adopted in corpus-based analyses are used to explore characteristics of abstracts written by Koreans and by native speakers.

Functional Analysis of Lexical bundles in rhetorical move of research article abstracts in Applied Linguistics

Xiaolei LIANG,Se-Eun Jhang(장세은) 새한영어영문학회 2021 새한영어영문학회 학술발표회 논문집 Vol.2021 No.10

This comparative study aims to explore frequent four-word lexical bundle found in each rhetorical Moves of research article (RA) abstract and the relationship between functional distribution of lexical bundles and RA Moves. The two corpora used in this study were Native Research Article Abstract Corpus and Chinese Research Article Abstract Corpus, which were self-built out of research article abstracts from international and Chinese journals of Applied linguistics. The two corpora were manually tagged with rhetorical move information. Results indicated that differences and similarities of lexical bundle preference were found in the two corpora. For frequent bundles in the five Moves, we found more research-oriented and stance-oriented bundles for Move 1, research-oriented bundles for both Move 2 and Move 3, text-oriented bundles for Move 4, and stance-oriented and text-oriented bundles for Move 5. Comparison of functional distribution of L1 and L2 group showed that L2 writers demonstrated a tendency to overuse research-oriented and text-oriented bundles in Move 3 and Move 4, and underuse them in Move 5. L2 writers used heavily certain bundles in their RA abstract moves, which may indicate a lack of variety in the move rhetorical realization. Findings from this study may provide a positive reference for academic writing instruction in English for Academic Purpose.

A Corpus-based Cross-regional Study on the English Language Features in Marine Accident Investigation Reports

Lyu, Wenyu,Jhang, Se-Eun(장세은) 새한영어영문학회 2019 새한영어영문학 Vol.61 No.4

This study aims to analyze the English language characteristics of marine accident investigation reports from four continents, i.e. America, Europe, Oceania, and Asia. The examination from the perspectives of lexical complexity, lexical density, keywords and key clusters not only shows differences in words and expressions between non-English speaking countries and English-speaking countries, but also indicates that there are varieties even within the English language itself. Additionally, implications and suggestions from the corpus-based study results are offered to teachers, students and related practitioners for English for specific purposes concerning aspects of the application of advanced vocabulary in writing and the varieties in English itself. This study can shed some light on the teaching and learning process of maritime English, in particular for the writing of marine accident investigation reports.
