Web2.0시대로 바뀌면서 더 이상 사용자들은 정보를 수동적으로 소비하고 공유하던 것에서 스스로 정보를 창출, 교류하는 능동적인 형태로 변화하는 모습을 보이게 되었다. 국내 토종 SNS인 미투데이(me2day), 싸이월드(cyworld), (c)로그 및 국외 SNS인 페이스북(Facebook), 트위터(Twitter)의 사용자가 급증하고 있으며 FramVille, Mafia War's Game 등의 SNG에 많은 사용자들이 이용하고 있다. 국내의 SNG는 아직 국외에 비하여 활성화되고 있지 않는 단계이다. 이에 국내 게임 시장의 장점인 온라인 게임과 요즘 유행하고 있는 SNS 개념을 통합하여 국내 게임 시장에 맞는 새로운 형태의 게임 즉, SNOG(Social Network Online Game, 소셜 네트워크 온라인 게임)로의 발전 방향을 유연성의 확대, 접근성의 확대, 사회성의 확대의 3가지로 제시하고자 한다.

최근 사이버 커뮤니티의 온라인 사회네트워크 관한 관심이 증대되고 있다. 사회네트워크의 최대의 과제는 인간 자본이 형성으로 이어질 수 있는가 이다. 사람들은 다른 사람들과 가상 커뮤니티 안에서 계속적인 접촉을 바탕으로 서로 관계를 형성하고 이것이 다시 사회네트워크로 이어져 인적네트워크를 형성한다. 사회 네트워크는 자신이 동원 할 수 있는 인적 네트워크의 총합이라 말할 수 있다. 본 연구의 목적은 사이버 커뮤니티 안에서의 사회 네트워크의 형성에 영향을 주는 변수를 찾기 위함이다. 우리는 연구를 위해 이용동기, 자기개방성, 상호작용성을 독립변수로 선정하고 종속변수로 지식공유, 관계강화 선정하여 다중회귀 분석을 실시하였다. 데이터는 대학생들을 대상으로 설문지를 이용하여 수집하였고, 표본으로 256명을 사용하였다. 그 결과 독립변수들이 지식공유에 정의 영향을 미치는 것을 확인 하였다. 하지만 관계 강화에는 정의 영향을 미치지 못하는 것으로 분석 되었다. 지식공유가 가지는 시사점으로는 현대의 전문화된 사회에서 자신의 분야가 아닌 타 영역에 관한 보다 쉽고 안정적으로 지식획득을 할 수 있고 타 영역에 접근할 수 있는 점이라 하겠다.

In line with network technology development and smart device penetration, the social network service (SNS) has expanded its influence. The SNS which is a service based on communication and sharing among people, has grown based on users' voluntary engagement and participation and its influence has appeared beyond the cyberspace into the overall areas of domestic and foreign culture and society. In particular, SNS-based real-time communication during diverse disasters, can help prevent further damage. By sharing information on social donation activities and environmental campaigns, people have used SNS as a tool to change the society in a more positive way. Such series of activities functioning as a power to change the society have been made much faster and wider through the help of a new media called SNS. To better understand such trends, we are required to study about the SNS and its user relationships first. In this context, this study sought to identify the effects of people's desire to build friendships through SNS on the voluntary and society-friendly activities of people. This study considers online pro-social behavior and proposes online citizenship behavior. Citizenship behavior has been examined in organization context. That is, organizational citizenship behavior explains an employee's pro-social behavior in an organization context. Organizational citizenship behavior is characterized by the individual's helping others and promoting the functioning of the organization. By applying organizational citizenship behavior to an online context, we propose online citizenship behavior, an individual's pro-social behavior in an online context. An individual's pro-social behavior, i.e., online citizenship behavior, could be considered as a way for the better management of online community and society. It also needs to examine the development of online citizenship behavior. This study examined online citizenship behavior from the friendship desire. Because online society or community is characterized by online relationships between members, the friendship between members would lead to pro-social behavior, i.e., helping others and promoting the functioning of the online society, in such online context. This study further examines the antecedents of friendship desire in terms of SNS interactivity with its four factors. The findings based on the survey from real SNS users explain that the three factors of SNS interactivity (connectivity, enjoyment, and synchronicity) increases online friendship desire which then increases online citizenship behavior significantly. This study contributes to the literature by examining the key role of online friendship desire in leading to online citizenship behavior and identifying its antecedents in terms of SNS characteristics. The findings in this study also provide guidance on how to manage online society and how to promote the effective functioning of SNS.

Online social networks contain a large amount of data that can be converted into valuable and insightful information. Text mining approaches allow exploring large-scale data efficiently. Therefore, this study reviews the recent literature on text mining in online social networks in a way that produces valid and valuable knowledge for further research. The review identifies text mining techniques used in social networking, the data used, tools, and the challenges. Research questions were formulated, then search strategy and selection criteria were defined, followed by the analysis of each paper to extract the data relevant to the research questions. The result shows that the most social media platforms used as a source of the data are Twitter and Facebook. The most common text mining technique were sentiment analysis and topic modeling. Classification and clustering were the most common approaches applied by the studies. The challenges include the need for processing with huge volumes of data, the noise, and the dynamic of the data. The study explores the recent development in text mining approaches in social networking by providing state and general view of work done in this research area.

With the rapid development of Internet and big data technology, various online social network platforms have been established, producing massive information every day. Hot topic discovery aims to dig out meaningful content that users commonly concern about from the massive information on the Internet. Most of the existing hot topic discovery methods focus on a single network data source, and can hardly grasp hot spots as a whole, nor meet the challenges of text sparsity and topic hotness evaluation in cross-network scenarios. This paper proposes a novel hot topic discovery method across social network based on an im-proved LDA model, which first integrates the text information from multiple social network platforms into a unified data set, then obtains the potential topic distribution in the text through the improved LDA model. Finally, it adopts a heat evaluation method based on the word frequency of topic label words to take the latent topic with the highest heat value as a hot topic. This paper obtains data from the online social networks and constructs a cross-network topic discovery data set. The experimental results demonstrate the superiority of the proposed method compared to baseline methods.

We study the antecedents to tie formation on an (Facebook-like) enterprise social media platform implemented to support cross-boundary connections. Research has produced mixed findings regarding the role of social media in cultivating bridging vs. closed networks. We examine the tie formation patterns of 1,386 enterprise social media users over a two-year period. Specifically, we observe who became (or chose not s become) "friends" with whom at the dyadic level and relate the decisions to various mechanisms that affect one's network to expand, constrain, or bridge. Using logistic and OLS regressions, we find that users tend to form ties via reciprocity and transitivity (with friends of friends), both of which help expand one's network. We also find strong networking tendency toward functional and hierarchical homophily (same business unit and same rank, respectively), which is likely to constrain one's network (closed network structure). We find that one's participation in various online interest groups is likely to open one's network (bridging network structure) while no evidence found for preferential attachment. Overall, we find that enterprise social media offers features, some of which are likely to foster bridging while others foster closed networks via different mechanisms.

In South Korea, as awareness of gender equality increased since the 1990s, policies for gender equality and social awareness of equality have been established. Until recently, however, the gap between men and women in social and economic activities has not reached the globally desired level and led to social conflict throughout the country. In this study, we analyze the content of online news comments to understand the public perception of gender equality and the details of gender conflict and to grasp the emergence and diffusion process of emerging issues on gender equality. We collected text data from the online news that included the word 'gender equality' posted from January 2012 to June 2017 and also collected comments on each selected news item. Through text mining and the temporal semantic network analysis, we tracked the changes in discourse on gender equality and conflict. Results revealed that gender conflicts are increasing in the online media, and the focus of conflict is shifting from 'position and role inequality' to 'opportunity inequality'.
