Recently, social network services have changed by moving towards an open platform where, as well as simply allowing the building of relationships among users, various types of information can be generated and shared. Since existing user reputation management methods evaluate user reliability based on user profiles, explicit relations, and evaluation, they are not suitable for determining user reliability on social media due to few explicit evaluation. In this paper, we analyze social activities on social media and propose a new user reputation management method that considers implicit evaluation as well as explicit evaluation. The proposed method derives positive and negative implicit evaluation from social activities, and generates user reputation information by field in order to consider user expertise. It also considers the number of users that participate in evaluation in order to measure user influence. As a result, it generates the reputation information of users who have no explicit evaluation and creates user reputation information that is more suitable for social media.

소셜 미디어가 확산되고 사용자가 증가하면서, 사용자들은 소셜 미디어를 통해 의견을 공유한다. 소셜 미디어는 실시간 정보에 대한 전달이 빠르며 데이터를 수집, 분석할 수 있다. 오피니언 마이닝은 텍스트로부터 사용자의 의견이 포함된 패턴을 추출하여 특정 제품이나 서비스에 대한 의견의 긍정, 부정 표현의 정도를 측정한다. 본 논문에서는 오피니언 마이닝을 기반으로 소셜 미디어 데이터에서 기업의 제품, 서비스와 관련된 사용자의 의견을 분석하여 긍정, 부정인지를 판단한다. 그리고 부정 패턴의 빈도를 통해 기업의 위기 상황을 인지하며, 위기 대응을 위한 4단계의 위기관리 모델을 제시한다. 또한 소셜 미디어에서 기업의 위기관리 사례를 확인하고, 표본조사를 통하여 평가 및 분석을 수행한다. 이 모델을 이용하여 방대한 소셜 미디어 데이터에서 기업의 제품이나 서비스에 대한 부정적 의견을 초기에 감지하고, 체계적으로 대응 할 수 있다.

This study investigated consumer convergence preferences for healthcare information service in social media using the multi-attribute utility theory. The multi-attribute utility theory is an approach for compositional modeling attributes wherein researchers compute the overall service utility by aggregating the evaluation results for attribute values. We found that healthcare information service consumers in social media evaluate the service preference through the multi attributes - Update, Cost, Usefulness, Usability, Reliability. And the study shows that individual preference by estimating weight of each attribute in the services influences the service use intention. So we believe that estimating preferences with multi-attribute utility theory will predict business success of the services in a new media, and for a successful business of the social media services marketers should assess the consumer's preference using the multi-attributes.

The use of social media in government has expanded steadily around the world on the basis of Web 2.0 technology. The government uses social media as a tool for enhancing transparency, participation, collaboration, and saving costs. However, the use of social media in the public sector has not only been positive. It has also been described as a double-edged sword. Most local governments in South Korea use social media for a variety of reasons but there has not been enough practical study of the effectiveness of social media use in the public sector. Local governments generally have positive views of their social media use but the real application of social media is not consistent in each local government. This study tried to determine the reality of social media use in local government and what factors influenced its use. The research analyzed the data from a survey conducted by the Korea Local Information Research & Development Institute (KLID) in 2015 and data from Facebook in each local government. The results show that most local governments were using Facebook for promotional purposes and local government officials similarly recognized that they were using Facebook well. However, local governments showed great differences in their use and practical effect. Meanwhile, the study found that population, financial independence, level of government, the entity operating social media, the median age, and whether social media are used for interaction or to gather opinions were the most influential factors that make a difference in utilization in local government.
