본 연구는 SNS 텍스트에서 형태소 분석기로 분석되지 않는 비정규토큰 유형 중 고빈도로 나타나는 의존명사 내포 어형의 형태소를 인식할 수 있는 LGG 기반 패턴문법 사전 구축과 그 성능을 평가하는 것을 목표로 한다. SNS 텍스트에서는 기존의 정형화된 텍스트와 달리, 띄어쓰기 오류로 인한 미분석어가 매우 높은 빈도로 나타나는데, 특히 의존명사를 포함한 유형이 20% 이상을 차지하며 가장 빈번한 것으로 나타났다. 이에 본 연구에서는 의존명사를 내포한 비정규토큰의 띄어쓰기 오류 문제를 효과적으로 처리하기 위해, 부분 문법 그래프(Local Grammar Graph: LGG) 프레임에 기반한 패턴문법 사전을 구축하였다. 이를 SNS 코퍼스에 적용하여 성능을 평가한 결과, 정확률 91.28%, 재현율 89%, 조화 평균 90.13%의 성능을 통해 본 연구의 접근 방법론의 유용성과 구축 자원의 실효성을 입증하였다.

스마트폰 보급의 활성화와 스트리밍 기술의 발전으로 모바일 기기를 통한 실시간 스트리밍 서비스가 확대됨에 따라 사용자는 실시간 방송의 시청은 물론, SNS를 통한 방송의 참여를 원하고 있다. 본 논문에서는 이러한 사용자 요구를 만족시키기 위해 기존 어플리케이션의 자체 서비스로 인한 안정성과 편의성 문제를 해결하고, 사용자와 방송 제작자 및 사용자들간의 커뮤니케이션을 제공하는 소통의 장으로서 역할을 수행할 수 있는 방법을 제시한다.

Recently, the development of smart devices such as smart phones and tablet PCs, with mobility, convenience and real-time computing, promotes proliferation and activation of social media. It also causes innovative changes in communication methods. Since 2010, researches in SNS (Social Networking Services) have focused on developing marketing strategies using SNS. On the other hand, the main purpose of this study is to provide a requirement analysis method of smart phone users by using content analysis of SNS. An information systems developed in this study in order to analyze content of SNS automatically because it is very difficult and time consuming to analyze it manually. In addition, this study compares the result of content analysis with that of Kano survey in order to examine consistency between the two results.

Owing to supply of smart phones and the diffusion of SNS, the number of peoples who are living, linked with us, is incomparably more than in the past. The continuous communication is essential in maintaining good relationship, so peoples have no choice but to seek for most efficient communication method in order to maintain good relationship. This thesis intended to advise how to construct next generation immersive multi-media system, using augmented reality and MPEG-V that have come to the fore recently. In addition, the SNS platform service of new type was suggested in this thesis, in connection with the pairing service. Now, we can create a town in a specific space like the real world, if we utilize the augmented reality that became possible by SNS service and we can talk and exchange informations in that space. This system would provide various services peoples wish to have, interlocking experiences through five senses like sense of vision, sense of hearing, sense of touch and etc..

Recently, the health-pleasure trend, which means enjoying health care through exercise or diet and certifying it on SNS is spreading to the MZ generation. This study examined the effect of personality traits on SNS upload behavior and subjective well-being related to health care. As a result, 1) parallel comparison and narcissism had a positive effect on the SNS upload attitude and intention, and the downward comparison had a negative effect on both SNS upload variable. Self-esteem had a positive effect only on the attitude of uploading SNS. Next, 2) self-esteem had a positive effect on both subjective well-being, while narcissism had a negative effect on stress, and parallel comparisons had a positive effect on life satisfaction. In other words, it was confirmed that comparisons with similar people had a positive effect on SNS upload behavior and their subjective well-being, while health care for self-show or recognition of others had a negative effect on their subjective well-being. The results of this study should be actively reflected not only for the marketing market but also for a media and cultural environment in which the MZ generation can lead a healthy life.

The social networking services (SNSs) have become popular among smartphone users, and one of the most popular services. In order to explain users' motivations toward SNS, this study considers uses and gratification theory which can explain individuals' motivations to select certain media channels. The purposes of this study is to investigate the relationships between motivations and addiction of SNS, and between addiction of SNS and decline in the subjective wellbeing. We examine moderating effects of social tie based on the social capital theory in the relationships between SNS addiction and decline in the subjective wellbeing. The motivations of SNS are subdivided into emotional motive (entertainment and fantasy) and cognitive motive (information share burden and challenge burden) based on the use and gratifications theory. The addiction of SNS is subdivided into time tolerance, withdrawal symptoms, interruption, and barrier of living. The data used in this study were collected from 286 SNS users through surveys. The data analysis in this study was performed using AMOS 17.0, and we used SEM(Structural Equation Modeling) methods in order to test the research model. The result shows that the emotional motive(entertainment and fantasy) and cognitive motive(information share burden and challenge burden) have an effect on the addiction of SNS. Especially emotional motive such as entertainment and users' fantasy toward SNS is an important factor that can cause SNS addiction. The addiction of SNS such as time tolerance, withdrawal symptoms, interruption, and barrier of living has an effect on the decline in the subjective wellbeing. Our result show that social tie partially moderates the relationship SNS addiction and decline in the subjective wellbeing. In addition, social tie between interruption of SNS and decline in the subjective wellbeing is an important moderating factor. The results focuses on the understanding toward relationship between SNS addiction based on the online and decline in the subjective wellbeing in the real world. The findings of this study also provides theoretical as well as practical implications which reflect the major features of SNS, and moderating effects of social tie based on the social capital.

Internet companies that utilize social network have increased in number. The introduction of diverse social media services facilitated innovative changes in e-business. Social network service (SNS), which is a domain of social media, is a web-based service designed to strengthen human relations in the Internet and build new social relations. The remarkable growth of social network services and the profit generation and perception of this service are the new growth engines of this digital age. Given this development, many global IT companies views SNS as the most powerful form of social media. Thus, they invest efforts to develop business models using SNS.2) This study verifies the impact of privacy exposure in SNS as a result of privacy invasion. This study examines the purpose of using the SNS and user's awareness of the significance of personal information, which are key factors that affect self-disclosure of personal information. This study utilizes theory of reasoned action (TRA) to provide a theoretical platform that describes the specific behavior and emotional response of individuals. This study presents a research model that considers negative attitude (negatude). In this model, self-disclosure in SNS is considered a TRA. TRA is a subjective norm, a behavioral intention, and a key variable of exposure behavior. A survey was conducted on college students at Y university in Seoul to empirically verify the research model. The students have experiences in using SNS. A total of 198 samples were collected. Path analysis was applied to analyze the relations of factors. The results of path analysis show the statistically insignificant impact of privacy invasion on negatude, subjective norm, behavioral intention, and exposure behavior. The impact of unrecognized privacy invasion was also considered insignificant. The impacts of intention to use SNS on negatude, subjective norm, behavioral intention, and exposure behavior was significant. A significant impact was also found for the significance of personal information on subjective norm, behavioral intention, and exposure behavior, whereas the impact on negatude was insignificant. The impact of subjective norm on behavioral intention was significant. Lastly, the impact of behavioral intention on exposure behavior was insignificant. These findings are significant because the study examined the process of self-disclosure by integrating psychological and social factors based on theoretical discussion.
