본 논문에서는 토픽 시그너처(Topic Signature)를 이용하여 댓글을 분류하는 시스템에 대해서 설명한다. 토픽 시그너처는 자질을 선택하는 방법으로 문서요약이나 문서분류에서 사용하는 방법이다. 댓글은 문장의 길이가 짧고 띄어쓰기가 거의 없으며 특수문자들이 많은 특성을 가지고 있다. 따라서 우리는 댓글을 7개의 음절로 나누고 이를 다시 Tri-gram으로 나누어 분류의 기본단위로 본다. 이 Tri-gram을 토픽 시그너처를 이용한 학습 단위로 사용하고, 학습한 자질을 베이지안(Bayesian) 모델을 사용하여 분류한다. 다양한 방법의 모델과 비교 실험을 통하여 구현한 시스템의 성능이 기존의 방법보다 상승되었음을 실험 결과를 통해 알 수 있었다.

인터넷의 발달로 대중의 여론에 영향을 주는 인터넷 매체의 신뢰성이 중요해지는 반면 최근의 익명성을 이용한 리뷰 조작 등의 사례는 대중들에게 막연한 의구심을 들게 한다. 본 연구에서는 이러한 사이버 여론 조작과 관련된 현상이 인터넷 게시판 등 웹사이트에도 존재하는지 여부를 수치적으로 살펴보기 위하여 댓글의 요소를 분석하고 내용을 코사인 유사도를 이용하여 비교하였다. 분석 결과 첫째, 댓글 내용의 유사성은 댓글 순위에 의한 게시글의 랭킹과 상관관계가 있었으며 분석 대상 2개 웹사이트에 대해서는 14.1%와 2.6%가 유사한 댓글로 구성되어 있었다. 둘째, 사이버 여론 조작에 일반적으로 이용되는 기법인 과다한 중복 게시 행위와 실제로는 동일인이지만 여러 명으로 위장한 것으로 추정되는 사용자를 파악 할 수 있었다.

With regard to the recent developments in public diplomacy, the increasing fusion of strategic communication appears necessary. China engages in public diplomacy with a strategic purpose to shape its national image abroad. Hosting diplomatic advocacy event is regarded as an instrument with expectations to present reliable and responsible image and promote international collaborations. The present research focuses on the Belt and Road Forum (BRF) in May 2017 with the objective to analyze its outcomes and influence on the international news agenda, news frames, and foreign citizens' comments online. The quantitative content analyses are used to compare the media reports (N=364) and Facebook users' comments on the selected news (N=957) between the US and Pakistan. Results reveal that Pakistani media provided more diverse frames and attributed more positive evaluations to the BRF than the US media. However, Facebook comments expressed more unfavorable opinions toward the BRF and China's image with rare differences between two countries. In conclusion, the BRF has served as an eye-catching advocacy of Chinese foreign policy, as it influenced the news agenda in two selected countries. However, news frames vary due to the differences in media system and the involvement in the BRF. China's public diplomacy practices follow a traditional top-down communication which needs meticulous subdivision of target stakeholders, delicate messaging strategies, and integrated tactics.

Background and objective: Instagram, an image-based social media, is being used as an important outlet for the communication and place marketing of public spaces. The purpose of this paper was to analyze how types of place-based content affect user reactions (Likes and Comments) on Instagram in order to provide basic data on the operation and utilization of social media by public places such as botanical gardens and arboretums. Methods: A total of 850 posts uploaded to the Instagram account of Kew Gardens from November 6, 2014 to July 3, 2020 were classified using 14 subject codes. Multiple regression analysis was performed to evaluate the user's reaction between the dependent variables ("Likes", "Comments") and the independent variables (14 subject codes). Results: The findings showed that user reactions appear to differ depending on the typology of the content, and "Likes" and "Comments" were presented in independent behavioral reactions. In particular, "close-ups of plants (botanic, macro)," "plant colony (botanic, wide)," "place-specific landscape (building, landscape)," "anniversary" and "information" showed positive impacts on both "Likes" and "Comments"which could lead to electronic word-of-mouth and content sharing. Conclusion: Based on these findings, it can be argued that the typology of a botanical garden's content can be used to determine factors that affect the immediate reactions and enhance engagement with users.

Subjects of the study consisted of 60 mothers and their children 10 boys and 10 girls each at the age of 3,4 and 5 The mothers' teaching language was analyzed on the basis of hoffman(1987)'s study and the types of information thant mothers and children exchanged during writing letters was analyzed by Burns and Casbergue (1992)'s categories. Frequency percentages and χ2 tests were used to analyze the data. The resuls of this study were as follows. 1. The types of the mothers' teaching language from the most to the least were mother-initiated statements mother-initiated questions and mother's responses to child's efforts. There were significant differences according to children's age in mothers' language. In the mother-initiated questions request questions were used most frequently and followed by interrogation questions and invitation questions next. The statements initiated by mothers were directive comments informative comments supportive comments insistence comments and invitation comments in order. Mothers' responses to child's efforts were corrects/controls additional cues confirmation promotion and praise in order. In all three types of the teaching language significant promotion and praise in order. In all three types of the teaching language significant differences were found according to children's age. 2. The types of information about writing were spelling content off task/preparation mechanical conventions and conceptual meaning of writing in order. Significant differences were found according to children's age. In the age group of 4-and 5-year-olds the mothers exchanged more information about spelling than the mothers of 3-years-olds who frequently used information about content and off task or preparation of writing the letter.

최근 유튜브가 큰 인기를 얻고 있다. 많은 연구에 따르면 소셜 미디어에서 상대적 박탈감이 나타나듯이 본 연구에서는 유튜브에서도 상대적 박탈감이 나타나는지 확인해보고자 한다. 그중에서도 유튜버의 경제적 지위를 잘 드러내는 명품 하울 영상을 중심으로 연구를 진행하였다. 명품 하울이란 많은 양의 명품 제품을 구매하여 보여주는 콘텐츠를 의미한다. LDA, TF-IDF, Word2Vec 기법을 이용하여 유튜브 댓글 분석을 진행하였다. 추가로 LSTM 학습 모델을 기반으로 댓글을 긍정적 그룹과 부정적 그룹으로 분류하였다. 연구 결과에 따르면 다수의 댓글이 긍정적인 의미를 내포하지만, 상대적 박탈감 등을 나타내는 부정적 의미의 키워드를 가진 댓글도 나타났다. 이러한 댓글에서는 자신과 유튜버의 경제적 모습을 비교하는 표현이 등장하였다. 특히 유튜버의 나이가 상대적으로 어리거나 스스로 명품제품을 구매할 능력이 되지 않은 것으로 보이면 상대적 박탈감을 표현하는 댓글이 증가하였다. 따라서 본 연구에서는 유튜브도 다른 소셜 미디어와 같이 이용자가 상대적 박탈감을 느낀 다는 것을 확인 할 수 있었다.

This study examines the effects of celebrity endorsed advertising from a new perspective of the prior research that emphasizes the matchup between the brand and the celebrity. Due to the recent sharing experiences of the celebrity and their fans on SNS, it is hypothesized that the shared stories would impact viewers' responses that are often expressed in their likes, dislikes, shares and comments on SNS. In this study, the episodic type of advertising is hypothesized to have more favorable and active responses from viewers than the typical celebrity image-focused ads would have. By crawling and analyzing viewers' responses on YouTube toward 12 BTS endorsed ads, the hypotheses are confirmed as higher ratio of likes, lower ratio of dislikes and significantly higher ratio of comments over both total views and total likes were found. For the rationale behind, total 1800 comments were categorized into 4 major content types such as attached, experiential, empathic and self-related ones that are all considered as important factors influencing the strong ad effect. The results showed that the episodic ads have marginally more emotional comments than the celeb image ads. The difference was only found in experiential and empathic responses but not in self-related responses. Contrary to the hypothesis, the comments expressing attachment were found more for the celebrity image-focused ads than the episodic ones. It does not seem to suggest that the celebrity image focused ads are better to capture viewers' attachment towards the celebrity and the ad endorsed, but that the episodic ads draw viewers into relatively deeper level of attachment such as empathy by perceiving the authenticity of the celebrity and the brand. In conclusion, the shared stories on SNS can be a factor in the match-up theory on celebrity endorsed ad effects.

본 연구는 유튜브 채널 비디터의 '브레이브걸스_롤린_댓글모음' 영상을 중심으로 댓글이 차트 역주행에 미치는 영향에 관해 분석하였다. 먼저, 이를 위해 채녈 주인인 비디터가 영상에 사용한 댓글이 어떻게 스토리텔링을 이룰 수 있었는지를 알아보았다. 또한 이 영상에 사용자들이 직접 작성한 댓글들을 "티핑 포인트" 법칙을 통해 분석함으로 인기의 이유를 조사했다. 그 결과, 이 영상은 브레이브 걸스를 군대 이야기와 연결시킴으로 스토리텔링을 만들었음을 알 수 있었다. 티핑 포인트에서 소수의 법칙은 군대임이 나타났고, 고착성의 요소는 백령도 공연에서 남긴 좋은 이미지가 메시지로 보였다. 마지막으로 상황의 힘 법칙에서는 코로나라는 어려운 현실 상황과 브레이브 걸스 멤버들과 관계자들의 댓글을 통한 직접적인 소통으로 인한 좋은 상황이라는 것을 알 수 있었다.
