        감성분석과 SVM을 이용한 인터넷 악성댓글 탐지 기법

        홍진주,김세한,박제원,최재현,Hong, Jinju,Kim, Sehan,Park, Jeawon,Choi, Jaehyun 한국정보통신학회 2016 한국정보통신학회논문지 Vol.20 No.2

        The Internet has brought lots of changes to us sharing information mutually. However, as all social symptom have double-sided character, it has serious social problem. Vicious users have been taking advantage of anonymity on the Internet, stating comments aggressively for defamation, personal attacks, privacy violation and more. Malicious comments on the Internet are creating the biggest problem regarding unlawful acts and insults which occur on the Internet. In order to solve the issues, several studies have been done to efficiently manage the comments. However, there are limitations to recognize modified malicious vocabulary in previous research. So, in this paper, we propose a malicious comments detection technique by improving limitation of previous studies. The experimental result has shown accuracy of 87.8% providing higher accuracy as compared to previous studies done. 인터넷을 통해 많은 정보를 얻고 많은 정보를 타인에게 제공하면서 개인의 삶의 양식에 큰 변화를 가져다주었다. 모든 사회 현상에는 양면성이 있듯이 인터넷 익명성을 이용하여 명예훼손, 인신공격, 사생활 침해등과 같이 악의적으로 이용하여 사회적으로 심각한 문제를 양산하고 있다. 인터넷 게시판의 악성댓글은 인터넷에서 발생하는 불법적인 언사나 행위와 관련하여 가장 대두되고 있는 문제이다. 이러한 문제를 해결하기 위해 많은 연구가 진행되고 있지만 악성댓글에 사용된 단어들은 변형이 많이 나타나기 때문에 기존 연구들은 이러한 변형된 악성어휘를 인식하는데 한계점이 존재한다. 이에 본 연구에서는 기존 연구의 한계점을 개선하여 악성댓글을 탐지하는 기법을 제안한다. 실험결과 87.8%의 정확도를 나타냈으며, 이는 기존 연구들에 비해 상당히 발전된 결과로 볼 수 있다.

        The purpose of this study (n = 325) were threefold: to explore Korean EFL undergraduates’ perspectives on an on-line course, to investigate the effects of the course on their TOEIC test scores, and to examine the relationship between the participants’ levels of English proficiency and their perspectives on the course. For data collection, the participants were given a survey questionnaire (asking their perspectives) and TOEIC practice tests (obtaining their TOEIC scores). The findings showed that the participants in general reported taking the course had helped them improve their listening ability, independent language studying capacity, and test taking skills. In fact, many of the participants improved their TOEIC test scores. In regard to the third research question, the participants in a high-level group significantly improved the TOEIC scores than those in a low-level group. Some more interesting findings and implications for English education will further be discussed in detail.

        황종배(Hwang Jong-Bai),안희돈(Ahn Hee-Don),한정임(Han Jeong-Im),임인재(Lim Injae),홍진주(Hong Jinju),심창용(Sim Changyong) 한국외국어교육학회 2007 Foreign languages education Vol.14 No.4

          This study quantitatively investigates foreign learners" acquisition of double particles in Korean. Some of the particles in Korean are jointly used with other particles and some are not, and the sequence of the particles determines the grammaticality of the double particles. Chinese and Japanese learners of Korean participated in the experiment in which they were asked to judge the grammaticality of a combination of a noun and double particles. The participants" judgment of the grammaticality of the double particles and their reaction time for the judgment were analyzed. The results of the study revealed that Japanese learners whose native language has a particle system similar to that of Korean performed better in the grammaticality judgment than Chinese learners whose native language shows no use of double particles. The advanced learners of Korean, regardless of their native languages, showed better judgment on the grammaticality of the use of double particles. This study also found that the type of double particles also affected the learners" judgment and that in the grammaticality judgment of ungrammatical joint of adverbial particles, most of the participants, regardless of their native languages and their Korean proficiency, scored much lower than in the judgment of the other types of double particles. The analyses of the participants" reaction time for the judgment showed congruent results with those of their grammaticality judgement.
