Social media platforms have become an integral part of our daily lives, and they generate vast amounts of data that can be analyzed for various purposes. However, the quality of the data obtained from social media is often questionable due to factors such as noise, bias, and incompleteness. Enhancing data quality is crucial to ensure the reliability and validity of the results obtained from such data. This paper proposes an enhanced decision-making framework based on Business Decision Management Systems (BDMS) that addresses these challenges by incorporating a data quality enhancement component. The framework includes a backtracking method to improve plan failures and risk-taking abilities and a steep optimized strategy to enhance training plan and resource management, all of which contribute to improving the quality of the data. We examine the efficacy of the proposed framework through research data, which provides evidence of its ability to increase the level of effectiveness and performance by enhancing data quality. Additionally, we demonstrate the reliability of the proposed framework through simulation analysis, which includes true positive analysis, performance analysis, error analysis, and accuracy analysis. This research contributes to the field of business intelligence by providing a framework that addresses critical data quality challenges faced by organizations in decision-making environments.

오늘날 소셜 네트워크 서비스(SNS)의 등장과 발전으로 인해 이전에는 관찰하기 힘들었던 다양한 형태의 정보가 쏟아져 나오고 있으며 또한 최근에는 사용자 각각의 개성과 기호에 따라 특정 관심 분야를 주제로 공유하는 서비스인 버티컬 SNS (Vertical Social Networking Service)가 주요 연구 분야로 떠오르고 있다. 특히 모바일의 GPS를 통해 수집된 지역 데이터(Geolocation Data)와 소셜 데이터를 통해 공간적 특성뿐 아니라 인문사회학적 측면을 관찰할 수 있어 다양한 연구에서 사용되고 있다. 본 연구에서는 이미지 기반 버티컬 SNS인 인스타그램을 통해 수집된 소셜 데이터를 분석하고 이를 통해 사용자의 공간적 맥락을 바탕으로 소셜 미디어(social media)의 기반을 둔 사용자의 경험을 측정하고자 한다. 따라서 본 연구에서는 사회적 데이터를 통한 경험 공유와 지리적 특성의 경험적 요소 간에 어떤 유형의 공간적 패턴이 존재하는지 탐색하고, 추출 된 데이터를 통해 공유된 경험 구조의 새로운 모형을 고찰하고자 한다.

Social media platforms such as Instagram and Facebook lead to potential security risks, which consequently raise public concerns about privacy. However, most people rarely make active efforts to protect their personal data, even though they have shown increasing concerns about privacy. Therefore, this study examines the factors that determine social media users' behavior of using privacy settings and testifies the existence of privacy paradox in such a context. In addition, it investigates the mediating effects of implementation intentions on the relationship between intentions and behaviors. In the study, we collected data through questionnaires, and the respondents were undergraduate and graduate students in South Korea. After a pilot test (n = 92) and a set of face-to-face interviews, 266 usable responses were retrieved for data analysis finally. The results confirmed the existence of the privacy paradox regarding the use of social media privacy settings. And the implication intention did positively mediate the relationship between intention and behavior in the context of social media privacy settings. To the best of our knowledge, our study is the first in the information privacy literature to introduce the notion of implementation intention which is a much more powerful explanation and prediction of actual behavior than the (behavioral) intention.

Purpose - This study aims to empirically verify the impact of media richness, social presence, and prior life satisfaction on various continual usage or withdrawal behaviors of SNS users via both a positive path of satisfaction and a negative path of relative deprivation. By identifying these causal paths, we observe dynamic interactions of SNS user psychology in a balanced view, and provide some implications about design principles for SNS providers. Research design, data, and methodology - We developed 16 hypothesis based on media richness theory, social presence theory, social comparison theory, the literature about relative deprivation, and the literature about the various reactions of IS users. The rich SNS media, social presence recognition among peer SNS users, and prior life satisfaction could generate positive experience, attitude, and virtuous behavioral intentions among SNS users. At the same time, rich media, low social presence, and low prior life satisfaction could generate relative deprivation and could increase withdrawal behavioral intentions such as refusal to provide information, misrepresentation of information, and removal of uploaded information in SNS. Scenario surveys were conducted to collect data from potential SNS users. Data from 357 surveys were collected and analyzed through a PLS algorithm to test the hypotheses. Results - Media richness, social presence, and prior life satisfaction could significantly increase perceived enjoyment, satisfaction, and behavioral intention of continual usage and knowledge sharing. They also could significantly decrease refusal and misrepresentation intention. Relative deprivation is significantly decreased only by prior life satisfaction. Relative deprivation could not significantly decrease satisfaction, but it could significantly increase misrepresentation and removal intention, which could be regarded as information distortion intention. Conclusions - SNS providers should focus on developing rich media and social presence support because these two variables could impact the positive experiences of SNS users. Moreover, the positive experiences could heavily influence SNS user behavior. Some management is needed to prevent relative deprivation and its consequences of misrepresentation and removal intention. SNS providers should prevent SNS users from excessive image misrepresentation and removal as this information distortion could be the source of relative deprivation.

소셜 미디어와 소셜 네트워킹 서비스의 확산은 사람들의 라이프 스타일에 많은 영향을 끼치고 있다. 이러한 확산 현상은 소셜 미디어를 통해 새로운 상품이나 서비스를 광고하고 촉진하려는 업계에 유용성을 제공할 뿐만 아니라 방대한 사용자 데이터의 획득도 가능케 하였다. 하지만 대다수의 연구들은 소셜 미디어에 대해 일반적인 통계적 접근 방법과 단편적 측정 방법을 사용하여 전시회의 성과를 측정하고 있어 소셜 미디어의 주 기능인 정보 교환의 측면을 고려하지 않고 있다. 따라서 본 연구에서는 MWC전시회의 트위터 데이터를 활용하여 정보 교환의 특징을 분석하려 한다. 이러한 분석방법은 전시 기획자 및 주관업체가 소셜 미디어의 효과를 객관적으로 측정할 수 있는 방법론을 제공하여 소셜미디어 활용 전략을 수립하는 데 큰 도움을 줄 수 있으리라 판단된다. 사용자 네트워크 분석을 통해 본 연구에서는 추가적으로 정보 교환의 지속가능성 측면에서 사회적 속성이 일반적 속성만큼 중요하다는 사실을 발견하였다. 결론적으로 본 연구는 MWC에서 정보를 교환하는 창구인 소셜 미디어의 사용에 따라 생성되는 데이터를 활용한 네트워크 분석 기법을 제안하는 한편 정보교환의 지속가능성에 대하여 매개 중심성과 중심성과 같은 사회적 속성의 특징을 밝혀냈다.

The purpose of this study is to investigate how uses and gratifications motivations increase social media stickiness, with a special focus on media engagement as a key mediator. Data were gathered via a survey questionnaire from Bangladeshi Z Generation social media users, which was quantitative in nature. For the analysis of 258 survey samples, structural equation modeling methodology was used. The results show that social media engagement and social media stickiness are positively impacted by uses and gratifications motivations such as social interaction, information, convenience, and entertainment. The study also found evidence of a relationship between uses and gratification motivations and social media stickiness, which is also mediated by emotional attachment. Understanding the motivations and gratifications sought by Z Generation users on social media platforms can help design strategies to enhance engagement and loyalty, ultimately leading to improved user retention and platform success. By identifying and addressing the specific needs and desires of the Z Generation, social media platforms can tailor their features, content, and user experiences to foster a stronger sense of connection and satisfaction, resulting in increased user engagement and prolonged usage.

Purpose The purpose of this study is to explore the pattern of user response and it's duration time through social media content response analysis. We also analyze the characteristics of content quality factors which are associate with the user response pattern. The analysis results will provide some implications to develop strategies and schematic plans for the operator of regional marketing on the SNS. Design/methodology/approach This study used mixed methods to verify the effects and responses of social media contents on the users who have concerns about regional events such as local festival, cultural events, and city tours etc. Big data analysis was conducted with the quantitative data from regional government SNSs. The data was collected through web crawling in order to analyze the social media contents. We especially analyzed the contents duration time and peak level time. This study also analyzed the characteristics of contents quality factors using expert evaluation data on the social media contents. Finally, we verify the relationship between the contents quality factors and user response types by cross correlation analysis. Findings According to the big data analysis, we could find some content life cycle which can be explained through empirical distribution with peak time pattern and left skewed long tail. The user response patterns are dependent on time and contents quality. In addition, this study confirms that the level of quality of social media content is closely relate to user interaction and response pattern. As a result of the contents response pattern analysis, it is necessary to develop high quality contents design strategy and content posting and propagation tactics. The SNS operators need to develop high quality contents using rich-media technology and active response contents that induce opinion leader on the SNS.

With the rapid spread of social media, video-sharing social media like YouTube has emerged as a consumption and distribution channel for entertainment goods such as music videos and movie trailers. In tourism research, there has been a lot of research of how the visual media such as movies and soap operas induced tourism. However, no studies have attempted to examine the role of social media as a music consumption channel and its impact on tourism. Expanding a body of media-induced tourism, we analysed the impact of video-sharing social media on music-induced tourism with a case of Korean pop music and inbound tourism to Korea. Developing a Web-crawler, we collected YouTube users' comments data on 166 Korean pop music video clips which were released from 2009 to 2012 with over 1 million view counts. Controlling many of the determinants of tourism and analysing country-by-country impact of YouTube comments with the panel data, we found that engagement of Korean pop music video clips on YouTube is a significant predictor for the flow of inbound tourists to Korea.
