The importance of business strategy for successful social media engagement has quickly increased as more businesses engage in social media. The importance is even greater for startup companies because startup companies are genuinely new to business, and they need to increase their presence in the market, and quickly access future customers. The objective of this paper lies in exploring key indicators of social media engagements by selected startup companies. The key indicators include two aspects of social media usages by the companies: i) overall social media activities, and ii) properties of network structure of the information flow platform provided by social media service. To better assess and evaluate the key indicators of social media usages by startup companies, the indicators will be compared with those of selected large established companies. Twitter is selected as a social media service for the analysis of this paper, and using Twitter REST API, data regarding the key indicators of overall Twitter activities and the Twitter follower-network of each company in the sample are collected. Then, the data are analyzed using social network analysis and hierarchical clustering analysis to examine the characteristics of the follower-network structures and to compare the characteristics between startup companies and established companies. The results show that most indicators are significantly different across startup companies and established companies. One key interesting finding is that the startup companies have proportionally more influencers in their follower-networks than the established companies have. Another interesting finding is that the follower-networks of startup companies in the sample have higher modularity and higher transitivity, suggesting that the startup companies tend to have a proportionally larger number of communities of users in their follower-networks, and the users in the networks are more tightly connected and cohesive internally. The key business implication for the future social media engagement efforts by startup companies in general is that startup companies may need to focus on getting more attention from influencers and promoting more cohesive communities in their follower-networks to appreciate the potential benefits of social media in the early stage of business of startup companies.

The proliferation of using social media and social networking services affects the lifestyles of people. These phenomena are useful to companies that wish to promote and advertise new products or services through these social media; these social media venues also come with large amounts of user data. However, studies that analyze the data of social media within the perspective of information exchanges are hard to find. Much of the previous research in this area is focused on measuring the performance of exhibitions using general statistical approaches and piecemeal measures. Therefore, in this study, we want to analyze the characteristics of information exchanges in social media by using Twitter data sets, which are relating to the Mobile World Congress (MWC). Using this methodology provides exhibition organizers and exhibitors to objectively estimate the effect of social media, and establish strategies with social media use. Through a user network analysis, we additionally found that social attributes are as important as the popular attribute regarding the sustainability of information exchanges. Consequently, this research provides a network analysis using the data derived from the use of social media to communicate information regarding the MWC exhibition, and reveals the significance of social attributes such as the degree and the betweenness centrality regarding the sustainability of information exchanges.

In these days, along with the extreme popularity of online social network services, it becomes an important problem understanding the role of social network in the research of message dissemination. Past studies of message dissemination over online social network services mostly consider the coverage of message dissemination and the methods to maximize it. But, these works lack of the consideration of the impact of multi channel social network, which has multiple communication channel with distinct properties of message transfer and various users with distinct channel preferences. In this paper, the new message dissemination model over multi-modal multi-channel social network, the Delay Weighted Independent Cascade Model, is proposed. The proposed model considers various channels including online social network service, email, SMS messaging, phone and mouth-to-mouth and their distinct message transfer properties. In order to consider the various user properties, the different value of probability of forwarding a message and the different preference of communication channel is considered. Moreover, the proposed model considers the distribution of user location and allows to analyze the properties of message dissemination under various scenarios. Based on the proposed model, a message dissemination simulator is generated and the message disseminations on various scenarios are analyzed.

최근, 스마트폰 가입자 수가 급격히 증가하는 가운데, 사람과 사람의 관계에 중심을 두는 서비스인 SNS가 급격히 성장하고 있다. 모바일 디바이스를 사용한 소셜 네트워크가 접목되어 사용자들 사이에 자연스러운 의사 교류 관계가 형성되며, 장소나 이벤트를 기반하여 빠르고 끊임없이 정보들이 발생하게 되었다. 그러나 너무 많이 발생하는 불필요한 데이터들로 인해 의미 있는 정보, 필요한 정보를 파악하는 데 어려움이 생긴다. 이러한 문제점을 해결하기 위해, 소셜 네트워크 서비스를 통해 제공되는 정보들 가운데 영향력 있는 정보가 무엇인지 판단하는 연구가 중요시 되고 있다. 본 논문에서는 소셜 네트워크 영향력 측정을 위해 장소를 기반으로 한 동적 소셜 커뮤니티에서의 소셜 네트워크 액티비티를 중심으로 이벤트에 대한 영향력을 측정하는 방법에 대해 고찰하고, 새로운 영향력 측정 방안에 대해 제안한다.

최근 IT기술발전으로 데이터 저장 및 처리비용은 하락하고 소셜네트워크 서비스 등이 확대되어 데이터의 양적 팽창이 가속화되면서 빅데이터에서 가치를 창출하려는 시도가 늘어나고 있다. 특히, 국내 스마트폰 이용자가 3천만을 넘어서면서 모바일 기기는 대량 데이터 생산의 원천이 되고 있다. 모바일 기기는 스마트시대 대표 통신채널인 소셜미디어 활용을 가속화 시키며 다양한 분야에서 영향력을 발휘하고 있다. 특히 일본과 아이티 지진피해, 강남역 침수 등 재난발생 시 피해상황 파악 및 경보, 정보교환 등에 소셜미디어 채널이 활발히 활용되면서 새로운 매체로 떠오르고 있다. 본 논문에서는 언어분석을 통해 소셜미디어 속에 재난이슈를 모니터링하고 소셜미디어가 재난예방 및 대응에 적극 활용되기 위해 필요한 기술개발 방안을 제시하고자 한다.

본 연구는 국내외 도서관의 소셜네트워크 서비스 현황을 살펴보고, 노드엑셀을 이용한 네트워크 분석 기법을 통해, 도서관 소셜미디어 활용도에 대해 조사하였다. 국내에서 소셜미디어 홍보를 제일 적극적으로 하고 있는 P대학의 트위터를 노드엑셀을 통해 매개중심성으로 분석해 본 결과 상위 파워트위터리안들을 알 수 있었으며, 추후 도서관 마켓팅에서 핵심이용자로 적극 관리할 필요성이 있음을 보여주고 있다. 홈페이지 이용도는 국내 의과대학 중 의학도서관 홈페이지상에 데이터베이스로 직접 URL 연동되어 있는 K대학 홈페이지를 보손(Voson)과 노드엑셀 네트워크 분석방법을 이용하여 분석해 본 결과, 상업출판사외에 NDSL이 가장 상위로 랭크되어 홈페이지의 활용도가 높음을 알 수 있었다.
