In the creative economy paradigm, motivation of the opportunity based startup is a continuous concern to policy-makers. Recently, bigdata anlalytics challenge traditional methods by providing efficient ways to identify social trend and hidden issues in the public sector. In this study the authors introduce a case study using social bigdata analytics for conducting policy analysis. A semantic network analysis was employed using textual data from social media including online news, blog, and private bulletin board which create buzz on the startup business. Results indicates that each media has been forming different discourses regarding government's policy on the startup business. Furthermore, semantic network structures from private bulletin board reveal unexpected social burden that hiders opening a startup, which has not been found in the traditional survey nor experts interview. Based on these results, the authors found the feasibility of using social bigdata analysis for policy-making. Methodological and practical implications are discussed.

A new technology has provided the nation, industry, society, and people with innovative and useful functions. National economy and society has been improved through this technology innovation. Despite the benefit of technology innovation, however, since technology society was sufficiently mature, the unintended side effect and negative impact of new technology on society and human beings has been highlighted. Thus, it is important to investigate a risk of new technology for the future society. Recently, the risks of the new technology are being suggested through a large amount of social data such as news articles and report contents. These data can be used as effective sources for quantitatively and systematically forecasting social risks of new technology. In this respect, this paper aims to propose a data-driven process for forecasting and assessing social risks of future new technology using the text mining, 4M(Man, Machine, Media, and Management) framework, and analytic hierarchy process (AHP). First, social risk factors are forecasted based on social risk keywords extracted by the text mining of documents containing social risk information of new technology. Second, the social risk keywords are classified into the 4M causes to identify the degree of risk causes. Finally, the AHP is applied to assess impact of social risk factors and 4M causes based on social risk keywords. The proposed approach is helpful for technology engineers, safety managers, and policy makers to consider social risks of new technology and their impact.

The spread of cloud computing, digital computing, and the popular social media platforms have led to increased growth of data. That growth of data results in what is known as big data (BD), which seen as one of the most strategic resources. The analysis of these BD has allowed generating value from massive raw data that helps in making effective decisions and providing quality of service. With Vision 2030, Saudi Arabia seeks to invest in BD technologies, but many challenges and barriers have led to delays in adopting BD. This research paper aims to search in the state of Big Data Analytics (BDA) in Saudi higher education sector, identify the barriers by reviewing the literature, and then to apply the design-reality gap model to assess these barriers that prevent effective use of big data and highlights priority areas for action to accelerate the application of BD to comply with Vision 2030.

Purpose Social media such as social network services, online forums, and customer reviews have produced a plethora amount of information online. Yet, the information deluge has created both opportunities and challenges at the same time. This research particularly focuses on the challenges in order to discover and track the service defects over time derived by mining publicly available online customer reviews. Design/methodology/approach Synthesizing the streams of research from text analytics, we apply two stages of methods of sentiment analysis and structural topic model incorporating meta-information buried in review texts into the topics. Findings As a result, our study reveals that the research framework effectively leverages textual information to detect, prioritize, and categorize service defects by considering the moving trend over time. Our approach also highlights several implications theoretically and practically of how methods in computational linguistics can offer enriched insights by leveraging the online medium.

With the rapid advancement of social media analytics and artificial intelligence, many studies have used online customer reviews as an important source to measure service quality in many industries, including the hotel industry. However, these studies have failed to identify the relative importance of different dimensions of service quality and their role in customer satisfaction. To fill this research gap, this study aims to identify the effects of service quality on hotel customer satisfaction from the multidimensional perspectives using sentiment analysis with self-training on online reviews. Additionally, the moderating role of the brand of origin for each service quality dimension is also investigated. Drawing on the SERVQUAL model and brand of origin concept, this study develops 12 hypotheses and empirically tests them using 30,070 online customer hotel reviews collected from TripAdvisor.com. The results indicated that overall service quality and each dimension of SERVQUAL significantly influenced customer satisfaction of hotels. The results also confirmed the moderating effects of brand of origin on overall service quality. However, the moderating effects of brand of origin for the tangible, reliability, and empathy dimensions of service quality were significant, whereas the effects for responsiveness and assurance were not. This study sheds new light on service quality measurement by analyzing the multidimensional features of service quality and the role of brand of origin in the hotel service context.

소셜미디어는 사회적 분위기를 나타내는 지표로서, 비즈니스, 경제, 정치 및 사회 전반을 아울러 다양한 현상들에 대해 분석하기 위한 목적으로 많이 사용되고 있다. 소셜미디어를 이용한 분석들은 사회적 분위기와 관련된 변화의 설명 변수로 활용되어 왔으며, 이에 대한 분석을 소셜 애널리틱스라 부르고 있다. 일반적인 국민들의 법감정과 사회적 분위기에 대한 지표로 활용되고 있는 소셜 애널리틱스를 이용한 연구는 많은 분야에서 이루어지고 있지만, 아직 충분한 연구가 이루어지지 않고 있던 영역이 법과 관련된 영역이다. 이에 본 연구는 대법원 판결과 관련하여 소셜미디어로부터 다양한 정보를 수집하고 소셜미디어가 법적 판결에 미치는 영향, 그 중에서도 한국의 현실에 맞게 상고 기각 여부 및 판결 기간에 어떠한 영향을 미치는지 알아보는 것을 목표로 한다. 본 연구는 법적 판결에 관하여 가장 활발히 소통하는 인터넷 기사 플랫폼을 대상으로 정보들과 댓글 및 대중의 반응에 대한 정보를 수집하여 진행되었다. 소셜미디어를 통해 확인된 대중들의 관심의 증가가 상고 기각 여부 영향을 미치지는 않았지만, 대중의 반응이 부정적일수록 대법원 최종 판결에 이르기까지의 재판 기간이 짧아지는 것을 확인하였다. 따라서, 소셜미디어는 제한적이지만 법적 판결에 영향을 미침을 확인하였다. 본 연구는 기존의 질적 연구에 의한 사례 연구와 달리, 법적 판결에 대한 소셜미디어의 다양한 정보를 수집하고 그 영향력을 빅데이터 관점에서 분석한 최초의 국내 연구라는 점에서 학문적 의의가 있다. 또한, 학술적 목적뿐만 아니라 필드에서도 쓰일 수 있는 법적 판결과 관련된 소셜미디어의 데이터베이스를 구축하였다는 점에서 실무적 의의도 있다고 할 수 있다.

Many methods of discovering social networking communities or clustering of features are based on the network structure or the content network. This paper proposes a community discovery method based on topic models using a time factor and an unsupervised clustering method. Online community discovery enables organizations and businesses to thoroughly understand the trend in users' interests in their products and services. In addition, an insight into customer experience on social networks is a tremendous competitive advantage in this era of ecommerce and Internet development. The objective of this work is to find clusters (communities) such that each cluster's nodes contain topics and individuals having similarities in the attribute space. In terms of social media analytics, the method seeks communities whose members have similar features. The method is experimented with and evaluated using a Vietnamese corpus of comments and messages collected on social networks and ecommerce sites in various sectors from 2016 to 2019. The experimental results demonstrate the effectiveness of the proposed method over other methods.
