Data commentary is an important text type in research articles; however, its discourse model is often challenging to access because it is embedded in the upper genres such as textbook, weather forecast, and journal article. This study aims to establish a discourse model of data commentary, with a focus on academic research papers in Economics and Business administration journals. To accomplish this, this study employs Move analysis and SF-MDA(Systemic Functional-Multimodal Discourse Analysis) to investigate the moves of data commentaries and the metafunctional meanings of each step. The results indicate that the data commentary discourse model consists of three moves: (1) summarizing the topic and methodology, (2) representing figure and numbers, and (3) analyzing and commenting on results. Additionally, 22 steps are identified for each move that creates metafunctional meaning: ideational, interpersonal, and textual.

Lee, Jee Won. 2017. “The Use and Discourse-Pragmatic Function of wo buzhidao in Naturally Occurring Mandarin Chinese Conversation”. The Sociolinguistic Journal of Korea 25(1). 167~192. This study investigates several aspects of Chinese (wo) buzhidao using both qualitative and quantitative methods, including its distributional properties and discourse-pragmatic functions in conversational contexts. This study has found that (wo) buzhidao occurs in conversational environments other than in reply to information questions and carries more interactive and social implications than had been previously proposed by previous studies. First, (wo) buzhidao marks the speaker’s uncertainty and concerns about the truth of the proposition expressed. Second, (wo) buzhidao constructs the speaker’s neutral position by disattending opinions, assessments, or troubles. Third, (wo) buzhidao avoids an explicit disagreement. The use of (wo) buzhidao as a stance marker allows the speaker to convey his/her consideration for the hearer’s face, and it can help to achieve a range of interactional goals. Native speakers of Mandarin Chinese employ (wo) buzhidao in conjunction with other interactive strategies to organize their speech via their recipient enabling mutual intersubjectivity.

Nam, Sin-Hye. 2015. “The Discourse Functions of Code Switching on SNS texts : focusing on the case of Facebook”. The Sociolinguistic Journal of Korea 23(1). 31~53. This study aims to figure out the discourse functions of code switching which appears in the texts posted on SNS, especially Facebook. In order to satisfy this purpose, this study observed and analysed several individual timeline pages whose owners have a plural language background, but live in a monolingual society. The results are as follows. First, a lot of code switching examples appeared in the observed texts, even though the writer lived in a monolingual society. Second, the unmarked code of the individual writers was their mother language and it was chosen when the posting was about the writer's everyday life and appeared as a longer passage. Third, when the writers chose their marked code, they had at least four particular reasons that were related to discourse functions; including or excluding a particular reader, using more effective words, emphasizing or watering down the implications of the text, and changing the speech act or topic. Finally, these results show that the community on SNS is closer to a plural lingual society rather than a closed monolingual community. On SNS, the users act as if they live in a multi lingual space and perform as plural linguals, although, in the reality, they live in a very monolingual society. And this is one of the important characteristics of a SNS discourse community.

Im Sun-hee and Kim Sun-hoi. 2014. A study on the discourse marker functions of “ye/ne” in Korean through analyzing the Sejong Corpus. The Sociolinguistic Journal of Korea 22(1). The expressions called discourse markers universally have three shared features, that is, connectivity, optionality, and non-truth-conditionality (Schourup 1999). Kim (1989), Lee (1993), and Kang (2009) have shown that the expressions “ye/ne” in Korean have the propositional meaning in some cases, but exhibit these features in other cases. Based on these previous studies, where the various functions of “ye/ne” were classified, this paper investigates, focusing on their discourse marker functions, the function-based frequencies of “ye/ne” occurring in the spoken component of the Sejong Corpus. From this investigation, the following results are derived: First, “ye/ne” is used much more frequently as a discourse marker than as a propositional meaning form, second, their most frequently used function is a back-chaneling one, and last but not least, “ye/ne” is also used within a speaker’s turn very frequently and “ye/ne” in these cases is not used for responding to another's utteran

이 연구의 목적은 there 존재구문의 논리 주어인 후치 명사구(post verbal NP)의 담화 기능을 주제 진행의 측면에서 제시하는 것이다. there 구문의 의미상의 주어는 정보성 위주의 설명에서는 관찰되지 않았던 담화 기능을 수행하는데, 이는 논리 주어의 정보성이나 단순한 의미 해석에 의존하는 것이 아니라 담화 흐름과 주제 응집성에 따라 그 기능을 달리한다는 것을 의미한다. 이 접근 방식은 학교 문법에서 there 구문의 의미 해석보다는 논리 주어가 후행 담화에서는 어떤 명사구로 연결되어 나타나는지를 명확히 설명하는 계기를 제공해 줄 것이다. 따라서 이 논문에서는 담화의 기본이 되는 문장과 나아가서는 담화를 구성하는 요소의 정보성, 그 요소와 선, 후행 발화와의 관련성, 그리고 화자와 청자의 상호 관계 등 담화에 관여한 모든 요소들을 고려하여 결정해야 한다는 담화 전개의 관점을 통해 there 존재구문에 나타난 후치 명사구의 담화 기능이 ‘주제 도입’임을 제시한다.

Young-Soon Kim. 2001. Discourse Functional Interpretation of the Word Order Variation. Studies Modern Grammar 24, 137-159. In many linguistic studies there has been a dichotomy between formal and functional approaches. This paper will attempt to connect the two approaches because linguistic expressions always simultaneously have formal grammatical properties and functional pragmatic properties. In order to do it, this study explains the concept of the discourse-grammar, demonstrates the discourse-grammar relationship of Korean, German, and English, and deals with the motivation of word order variation in English. There are expressions of discourse functions in English, for example, the left attachment and the right attachment. The former has the interpretation of marked topicalization and the latter has the effect of creating a new focus of statement. The outline of results in this study is as follows: Korean and German are pragmatical languages, which make use of grammatical means to cope with discourse-functional requirements in quite a different way from English.

Sun Ok Park. 1998. Differences in Discourse Functions of Modal Auxiliaries and Quasi-Modals. Studies in Modern Grammar 13, 107-131. The main concern of this study is to provide the English learners with the differences in discourse functions of will and be going to and suggest the differences can be applied to other modal auxiliaries and quasi-modals. Will has hypothetical condition and the speaker reaches his or her subjective prediction using the background experience and common sense. Be going to has present indication for the future event, so the speaker reaches his or her prediction based on the actual condition. The modal auxiliaries, must and can also have the speaker`s subjectivity while the corresponding quasi-modals, have to and be able to don`t.
