Recently, social network service (SNS) is actively used by public. Among them, Twitter has a lot of tweets including sentiment and it is convenient to collect data through open Aplication Programming Interface (API). In this paper, we analyze social issues and suggest the possibility of using them in marketing through sentimental information of users. In this paper, we collect twitter text about social issues and classify as positive or negative by sentiment classifier to provide qualitative analysis. We provide a quantitative analysis by analyzing the correlation between the number of like and retweet of each tweet. As a result of the qualitative analysis, we suggest solutions to attract the interest of the public or consumers. As a result of the quantitative analysis, we conclude that the positive tweet should be brief to attract the users' attention on the Twitter. As future work, we will continue to analyze various social issues.

The basic search engine on Twitter shows not only tweets that contain search keywords, but also all articles written by users with nicknames containing search keywords. Since the tweets unrelated to the search keyword are exposed as search results, it is inconvenient to many users who want to search only tweets that include the keyword. To solve this inconvenience, this study improved the search function of Twitter by developing an algorithm that searches only tweets that contain search keywords. The improved functionality is implemented as a Web service using ASP.NET MVC5 and is available to many users. We used a powerful collection method in C# to retrieve the results of an object, and it was also possible to output them according to the number of 'retweets' or 'favorites'. If the number of retrieved numbers is less than a given number, we also added an exclusion filter function. Thus, sorting search results by the number of retweets or favorites, user can quickly search for opinions that are of interest to many users. It is expected that many users and data analysts will find the developed function convenient to search on Twitter.

소셜 네트워크 서비스(Social Network Service, 이하 SNS)는 온라인상 동일한 관심사를 가진 사람들 간의 인적 네트워크 형성을 지원하는 서비스로 우리나라에서도 '아이러브스쿨'과 '싸이월드'를 비롯하여 많은 서비스들을 접할 수 있다. 이러한 서비스가 최근 해외에서 열풍이 일고 있는데, '트위터'와 '페이스북' 등이 대표적이다. '트위터'와 '페이스북'은 미국에서 시작한 서비스임에도 불구하고 지난해 6월부터 국내에도 폭발적인 서비스 참여가 이루어지면서 높은 성장을 거두고 있다. 하지만 SNS의 인기가 높아지면서 그에 대한 보안위협도 증가하고 있다. 본 논문에서는 SNS의 활용과 그 중요성이 점차 확대됨에 따라 발생할 수 있는 SNS 환경에서의 역기능은 어떤 것이 있는지 살펴보고 대응방안을 알아보고자 한다.

This study is critical research on the forming public opinion of SNS and participation behavior. Twitter is a typical SNS service, free school food and 10.26 re-and by-elections during the formation of public opinion on the impact have been investigated. Formation of public opinion about Twitter's analysis of the first research question, The case of free meals to support the Mayor Oh, rather than against Twitter were influential. 10.26 re-and by-elections Twitter in space, the Park' candidate than Na' candidate has formed a favorable opinion. Power twitterian and twitterian on the behavior of the second study involved analysis of the problem, For free meals, power twitterian were responsible for leading the public opinion. For 10.26 re-and by-elections, Power twitterian were more Park' candidates than Na' candidates. In addition, Park' candidates of twitterians were communicating more. Through traditional media in the process of forming public opinion was swayed by public opinion to the target people simply but SNS age people involved in the production and distribution of the issue and the issue has a leading role.

Twitter has been continuously growing since October, 2006. Especially, not only the users and the number of messages have been increasing but also a new concept in social networking called 'micro blogging' has diffused. Within Korea, service such as 'me2day' has already been introduced and the improvement of internet accessibility within mobile devices is expected to expand the 'micro blogs'. In this point, this research is executed to study the new medium, 'micro blog'. To do so, we collected and analyzed Twitter logs of Korean users. Especially, we were curious about the extreme heavy users using Twitter, despite of the linguistic and cultural barrier of the foreign service. Who they are, why and how they use the 'micro blog'. First, we reviewed the general aspect of followers and messages by collecting a certain number of random samples. Using the Lorenz curve we found out that there was the imbalance within the users and based on this phenomenon we deducted an extreme heavy user group. In order to perform further analysis, log analysis was performed on the extreme heavy users. As the result, the users used multiple mobile and desktop 'Twitter' clients. The usage pattern was similar to that of internet usage time but was used during their "micro" time. The users using 'Twitter' not only to spread messages about important information, special events and emotions, but also as a habitual 'chatting tool' to express ordinary personal chats similar to SMS and IM services. In this research, it is proved that 68% of the total messages were ordinary personal chats. Also, with 24% of the total messages were retweets, we were able to find out that virtually connected 'people' and 'relationships' acted as the dominant trigger of their articulation.

Social Network Service (SNS) such as Twitter and Facebook has explosively grown nationwide since iPhone was introduced to Korea in 2009. In addition, KakaoStory has recently opened and joined to the SNS market, and it has grown to one of the most popular SNS in the domestic market in a short period of time. Social Network Service supports not only the formation of relationship between SNS users in common interests but also various activities such as management of personal connections and the sharing of information or contents. These three types of SNS have several common functions of sharing and distributing various contents rooted on the personal relationship formed through SNS. As each SNS user has specific reasons for the use of each service, a survey was conducted targeting those who use all of Twitter, Facebook, and KakaoStory was drawn by the statistical analyses of survey answers on users' reasons for each service. This result of study suggests factors to consider in order to exploit a new SNS or to enhance an existing service and can be used as a standard of which SNS for users to select for their own different purposes. It will also provide the basic data for the trust formation, one of the ethics in the upcoming Social Era.

본 논문에서는 트위터를 기반으로 정서분석을 수행하여 사용자에게 제시해주는 시스템인 BEOLTONG을 제안한다. BEOLTONG은 최근에 주목 받기 시작해 많은 사람들이 사용하고 있는 트위터의 장점인 풍부한 데이터와 인적 네트워크를 정서분석에 활용하여 효과적인 정서분석을 수행하고, 그 결과를 그래프와 이미지 등을 사용하여 가시적으로 사용자에게 보여줌으로써 좀 더 직관적으로, 알기 쉽게 정서분석 결과를 보고 활용할 수 있도록 한다.

트위터는 대표적인 소셜 네트워크 서비스이며 스마트 기기의 발달로 사용자 수뿐만 아니라 생성되는 트윗의 수도 지속적으로 늘고 있다. 또한 트위터는 인증과정을 통하여 API 요청을 제한해 데이터의 수집이 어렵기 때문에 트위터 기반 연구를 위해서는 빅 데이터를 처리하기 위한 분산처리 기술이 요구된다. 본 논문에서는 네트워크로 연결된 다수의 클라이언트를 이용해 계정과 트윗의 수집에 용이하고 수집한 데이터를 분석할 수 있는 기능까지 추가한 분산처리 시스템인 DiSAnT을 소개한다.

최근 스마트폰의 사용이 보편화되면서 많은 양의 온라인 뉴스가 다양한 경로를 통하여 서비스되고 있다. 한편, 실시간으로 제공되는 뉴스의 양이 방대해지면서, 언론사에서 톱 뉴스로 제공하는 토픽과 달리, 실제 사용자들에게 화제가 되고 있는 토픽을 선별하는 데 어려움이 있다. 많은 사용자들이 실생활에서 작성하고 공유하는 트위터는 실제 사람들 사이에 화제가 되고 있는 토픽을 담고 있는 경우가 많다. 이러한 트렌드를 뉴스와 연계시키면 화제가 되는 트렌드 뉴스를 사용자에게 제공할 수 있다. 본 논문에서는 클라이언트-서버 모델을 기반으로 실시간으로 사용자 트위터를 분석하여 추출된 트렌드를 기반으로 관련 뉴스를 검색하여 제공하는 시스템을 제안한다. 클라이언트를 통해 수집한 트위터 단문에서 서버는 화제가 되고 있는 트렌드를 추출하고, 이를 기반으로 Google 등을 통해 관련 뉴스를 검색하여 클라이언트에게 전달한다. 이 모든 과정을 실시간으로 제공하기 위한 알고리즘을 제안하고 프로토타입 시스템을 통하여 그 성능을 평가한다.
