Social Media transformed the mass media based information traffic, and it has become a key resource for finding value in enterprises and public institutions. Particularly, in regards to disaster management, the necessity for public participation policy development through the use of social media is emphasized. National Disaster Management Research Institute developed the Social Big Board, which is a system that monitors social Big Data in real time for purposes of implementing social media disaster management. Social Big Board collects a daily average of 36 million tweets in Korean in real time and automatically filters disaster safety related tweets. The filtered tweets are then automatically categorized into 71 disaster safety types. This real time tweet monitoring system provides various information and insights based on the tweets, such as disaster issues, tweet frequency by region, original tweets, etc. The purpose of using this system is to take advantage of the potential benefits of social media in relations to disaster management. It is a first step towards disaster management that communicates with the people that allows us to hear the voice of the people concerning disaster issues and also understand their emotions at the same time. In this paper, Korean language text mining based Social Big Board will be briefly introduced, and disaster issue detection model, which is key algorithms, will be described. Disaster issues are divided into two categories: potential issues, which refers to abnormal signs prior to disaster events, and occurrence issues, which is a notification of disaster events. The detection models of these two categories are defined and the performance of the models are compared and evaluated.

최근 공공기관에서 다양한 목적으로 소셜미디어를 활용하는 사례들이 나타나고 있다. 우리나라의 경우 대부분의 지방정부에서 소셜미디어를 사용하고 있지만 소셜미디어 사용에 대한 실증적 연구는 충분하지 않다. 현재 우리나라의 지방정부들은 소셜미디어에 사용에 대해 대체로 긍정적인 평가를 하고 있지만 실제 활용에서는 일관된 모습을 확인하기 어렵다. 이러한 상황에서 본 연구는 지방정부의 활용 현황을 확인하고 활용에 영향을 주는 요인은 무엇인지를 판단 하고자 하였다. 이를 위하여 한국지역정보개발원에서 2015년 조사한 설문조사 결과와 각 지방자치단체들의 페이스북 활용 현황 자료를 토대로 분석을 진행하였다. 조사결과 지방자치단체는 대부분 홍보 목적으로 페이스북을 활용하고 있었으며, 자신들이 페이스북을 잘 활용하고 있다고 평가했다. 그러나 실제 활용에는 지방자치단체마다 큰 차이를 보였다. 한편 이렇게 지방자치단체의 활용에 차이를 가져오는 영향요인은 인구, 재정자립도, 단위, 전담 조직, 연령, 그리고 소셜미디어 활용 목적이 소통 및 의견수렴일 경우 로 확인되었다.

Climate change is a constant threat to human life, and it is important to understand the public perception of this issue. Previous studies examining climate change have been based on limited survey data. In this study, the authors used big data such as news articles and social media data, within which the authors selected specific keywords related to climate change. Using these natural language data, topic modeling was performed for discourse analysis regarding climate change based on various topics. In addition, before applying topic modeling, sentiment analysis was adjusted to discover the differences between discourses on climate change. Through this approach, discourses of positive and negative tendencies were classified. As a result, it was possible to identify the tendency of each document by extracting key words for the classified discourse. This study aims to prove that topic modeling is a useful methodology for exploring discourse on platforms with big data. Moreover, the reliability of the study was increased by performing topic modeling in consideration of objective indicators (i.e., coherence score, perplexity). Theoretically, based on the social amplification of risk framework (SARF), this study demonstrates that the diffusion of the agenda of climate change in public news media leads to personal anxiety and fear on social media.

This study examined the overall relationship between information privacy concern, need for uniqueness (NFU), and disclosure behavior to explain the personal factors that drive data-sharing on Facebook. The results of an online survey conducted with 222 Facebook users show that among diverse data that social media users disclose online, four distinct factors are identified: basic personal data, private data, personal opinions, and personal photos. In general, there is a negative relationship between privacy concern and a positive relationship between the NFU and the willingness to self-disclose information. Overall, the NFU was a better predictor of willingness to disclose information than privacy concern, gender, or age. While privacy concern has been identified as an influential factor when users evaluate social networking sites, the findings of this study contribute to the literature by demonstrating that an individual's need to manifest individualization on social media overrides privacy concerns.
