소셜 네트워크 서비스의 하나인 트위터는 팔로우를 통하여 사용자 간의 관계를 맺을 수 있다. 트위터 사용자들은 다양한 팔로워들이 존재한다. 이 팔로워들은 사용자에 대한 호감을 가지고 팔로우 하거나, 맹목적으로 추종하거나, 부정적인 의견을 지니고 사용자의 행동과 글을 관찰하기 위해 팔로우할 수도 있다. 본 논문에서 사용자에게 팔로워들이 어떠한 목적으로 그 사용자를 팔로워의 행태를 분석하는 모델을 제안한다. 대상사용자의 영향력 있는 팔로워를 추출하고, 팔로워의 리트윗 정보, 프로파일, 최신 트윗의 감정분석을 통해 지지자, 중립, 비지지자로 분류한다. 제안 방법의 유효성을 검증하기 위해 트윗 데이터에서 정치인과 언론인 5 명의 팔로워들 중 무작위로 3 만명을 추출하여 실험하였다. 실험 결과 영향력 있는 사용자 추출을 통한 지지 팔로워 추출이 효과적임을 알 수 있다.

This study examines the feelings of positivity and negativity generated through upward social comparison and explores the impact of the results of the emotions on SNS users' posting behavior. In particular, this study aims to systematically identify the influence of upward social comparison on SNS followers and uploaders' SNS usage behavior and the structural principle of social network circulation in which followers become uploaders again. According to the analysis, interaction-oriented followers made negative upward social comparison and positive upward social comparison, while negative upward social comparison reduced the publication of independence tendency. However, positive upward social comparison has been shown to increase both independent and interactive postings. The results of this study are meaningful in that SNS has expanded the results of prior studies, in which social comparison theories were biased toward negative upward comparisons, to positive upward comparisons. In addition, this study suggested a practical strategy for SNS platform operators on how SNS users would not deviate from other platforms.

This study investigates the posting strategies of influencers for sales: what kind of contents should the influencers provide and how? Influencers used to have seven days of advertising period before the event date (sales begins) and provide both (or either) commercial and (or) non-commercial contents. Some influencers have large number of followers, while others have very small followers. We empirically investigated whether the sequence of posting the commercial and non-commercial contents influence sales, and whether such effects are susceptible to the size of followers. Through the analysis of 1,153 events of 298 influencers on Instagram, we found that commercial contents are more important than non-commercial contents for both small and large influencers. In more detail, the quantity of commercial contents is very important for the large influencers, while the quality of commercial contents is important for small influencers.

최근 조직 내 정보시스템이 제공하는 지식과 정보에 대한 공유와 교환이 더 이상 성공적이라고 판단되지 않음에 따라 그 대안으로써 가상공동체(Virtual Community)가 주목받고 있다. 그러나, 가상공동체에서 살아있는 지식과 정보의 공유를 위해서는 공동체 안의 구성원인 리더와 구성원(팔로워) 들의 상호작용을 통한 몰입이 매우 중요하다는 인식이 확산되었다. 그러나, 이러한 몰입에 영향을 주는 리더-구성원 간의 영향관계는 충분히 연구된 바 없다. 이에 본 연구는 가상공동체에서 리더의 리더십 스타일과 팔로워의 특성 그리고 이들 간의 동기와 신뢰가 가상공동체의 몰입에 미치는 인과관계에 대해 분석하고자 하였다. '지각된 리더의 배려'로 측정된 '서번트 리더십'과 '지각된 리더의 조직지향'을 통해 측정된 '변혁적 리더십'이 구성원의 팔로워십과 동기, 리더와 조직에 대한 신뢰에 어떠한 영향을 미치는지 460명의 가상공동체 구성원을 통해 실증적으로 분석하였다. 분석결과 서번트 리더십과 구성원의 팔로워십 특성이 구성원의 몰입에 있어서 중요한 역할을 수행함을 알 수 있었다.

웹 2.0의 기술이 보급됨에 따라 소셜 네트워크 서비스에 대한 관심이 증가하였다. 국내에서는 싸이월드, 미투데이 등과 같은 서비스가 널리 사용되고 있으며 최근 급부상한 트위터는 여러 분야에서 관심을 받고 있다. 트위터는 팔로워나 트윗 등 활동 정도에 따라 랭킹 서비스가 제공되고 있지만 랭킹은 그들 사이의 관계를 세부적으로 나타내지 못한다. 본 논문에서는 트위터의 사용자들 사이에 존재하는 관계를 시각적으로 나타내는 도구에 대해 개발한다. 국내 사용자 중 팔로워의 랭킹에 따른 사용자를 이용하고, 시각화를 위해 생물학적 데이터를 네트워크로 나타내는 Cytocape 플랫폼을 사용한다. 사용자 간의 관계를 나타내는 네트워크를 통하여 온라인상에서 영향력 있는 사용자들의 관계를 나타내고 그들의 관계를 수치로 분석한다. 또한 복잡한 네트워크로부터 선택된 노드와 관련된 연결만을 추출하는 기능을 제공하여 온라인상의 관계를 상세하게 나타낸다.

This study examines the effects of SNS fashion influencer's authenticity on the followers' relationship maintenance intention and product purchase intention through the mediating role of fanship. In addition, influencer's attractiveness is proposed as a moderator affecting the authenticity on fanship; in addition, authenticity is operationalized as honesty and expertise. A written survey is developed for 181 female Instagram users. The analyses of the data yields the following findings. First, honesty has a positive effect on fanship, relationship maintenance intention and purchase intention, while expertise affects fanship and relationship maintenance intention, but does not have a significant effect on purchase intention. Second, honesty and expertise have a positive effect on follower behavior intention through the partial mediation of fanship. Third, social attractiveness and physical attractiveness have a significant effect on fanship. However, all interaction effects between authenticity and attractiveness are not significant. Unlike authenticity, attractiveness has no direct effect on follower behavior intention. This study verifies the critical role of authenticity for an influencer in the context of SNS marketing and commerce, as this factor leads to followers behavioral intention as well as fanship in both direct and mediated paths.
