This study measured the effects of fake news and propaganda on managing information on COVID-19 among the Nigerian citizenry. This study examined sources of information on COVID-19 available to the people, evaluated reasons behind spreading fake news, examined how fake news has affected the spread of COVID-19 pandemic in Nigeria, established the consequences of fake news on managing COVID-19 pandemic and as well identified ways to contain fake news at a time like this in Nigeria.It is a survey with a sample size of 375 participants selected using simple random technique. Instrument of data gathering was questionnaire widely distributed in the six geo-political zones of Nigeria using Survey monkey. Data was analysed using frequencies, counts and percentages, tables and charts. Findings revealed that people rely more on radio, television, and social media for information on COVID-19. Fake news is spread by people mostly for political reasons and intention to cause panic. In Nigeria, fake news has led to disbelief of the existence of the virus thereby leading to violation of precautionary measures among the citizenry and lack of trust in the government. Concerted effort on the part of the government is required to give public enlightenment on the danger of fake news. Also, directorate of anti-fake news should be established to censor and reprimand sources of fake news. People should always check source of information to confirm its credibility and be weary of sharing unconfirmed information especially on the social media.

The paper examines the reaction of the Z-Vietnam generation to online TV advertising (TVC), which elements of online TV advertising has a positive influence, which factors do not affect or negatively affect their consumption decisions for the advertised goods. Data for the study was collected from 300 Vietnam's Generation Z in Ho Chi Minh City through live interviews or questionnaires through Google Docs Forms, with over 30 questions. The six basic factors that influence the reactions of Generation Z consumers are information, entertainment, irritation, credibility, interaction, and advertising value. The research results show that, due to the influence of social media and generational characteristics, most consumers of the Generation Z in Vietnam have a favorable attitude towards online TV advertising, and they appreciate this form of advertising. Information element, irritation, credibility and entertainment have a strong and positive impact on TVC. The other two factors are advertising value and interaction, which does not significantly affect the reaction of this generation. This study needs to be checked and reviewed by subsequent studies on a larger scale and in a wider scope because the study only conducted random sampling on a small scale, did not meet the requirements for representation and generality.

Nowadays, fake news from newspapers and social media is a serious issue in news credibility. Some of machine learning methods (such as LSTM, logistic regression, and Transformer) has been applied for fact checking. In this paper, we present Transformer-based fact checking model which improves computational efficiency. Locality Sensitive Hashing (LSH) is employed to efficiently compute attention value so that it can reduce the computation time. With LSH, model can group semantically similar words, and compute attention value within the group. The performance of proposed model is 75% for accuracy, 42.9% and 75% for Fl micro score and F1 macro score, respectively.

As online social networks are used as a critical medium for modern people's information sharing and relationship, their users are increasing rapidly every year. This not only increases usage but also surpasses the existing media in terms of information credibility. Therefore, emerging marketing strategies are deliberately attacking social networks. As a result, public opinion, which should be formed naturally, is artificially formed by online attacks, and many people trust it. Therefore, many studies have been conducted to detect agents attacking online social networks. In this paper, we analyze the trends of researches attempting to detect such online social network attackers, focusing on researches using social network graph characteristics. While the existing content-based techniques may represent classification errors due to privacy infringement and changes in attack strategies, the graph-based method proposes a more robust detection method using attacker patterns.

The purpose of this study is to provide an effective program contents of information supplied by broadcasting media with the aim of developing health program models. Health programs which have been aired and are being aired on KBS I radio, KBS, EBS, Cable TV and SBS radio were analyzed in order to understand the issues of current health programs and to design a plan for improvement. In order to address current issues of health programs, the range of health information should be extended to meet various expectations from the public audience, in addition to dealing with diagnosis and treatment of illnesses. Programs should be capable of encompassing various issues such as health practice, prevention, information on medical facilities, public health policies, daily health information, and the role of patients. As health programs function as major information sources for health services, it is necessary to raise the quality and credibility of broadcasting. Broadcasting agencies has a responsible role for public health promotion through health programs. In order to make it possible for broadcasting to fulfill its social responsibility, it is advisable to develop programs that have a clear understanding of what is the cognition of the public and the level of demand in regard to health programs.

On a huge space of information called the Internet, users can use a smart mobile web to get information on various intellectual fields and can access to various Medias such as personal blogs and social networking sites (SNS). This is why a vast amount of information on the web has been effectively managed and researched nowadays through a technology named Semantic Web. However, it still needs for an improvement for studies on searching for intellectual information, though it is enhanced to integrate variously spread information and search for intellectual information user-oriented. Thus, this study aims to research on searching information and knowledge spread around a knowledge-filled information space, which can improve credibility according to user-oriented logic.

Purpose Recently, Internet personal broadcasting has been widely spreaded as a new media type by replacing traditional legacy media such as TV. Considering this phenomenon, this study aims to explore the effect of Aristoteles' persuasion factors on Internet personal broadcasting from a rhetorical view. The reason why users watch the Internet personal broadcasting is that they are persuaded by creator's expertness, empathy, or content usefulness. These factors can be regarded as persuasion factors. Therefore, with Aristoteles' rhetorical persuasion factors composed of ethos, pathos, and logos, this paper tries to investigate how persuasion factors affect user's emotional\ attachment and voluntary donation intention. Design/methodology/approach This paper proposes a model of the relationships among three rhetorical factors, user's emotional attachment, and donation intention. Specifically, ethos is regarded as creator's expertness and trustworthiness, and pathos refers to creator's empathy and social interaction. Last, logos refers to content usefulness and credibility. For testing a hypothetical research model, this study collected 468 surveys and empirically tested hypotheses using a structural equation model. Findings This study investigated how rhetorical factors (ethos, pathos, and logos) and emotional attachment further influence user's donation intention. The findings suggest that rhetorical factors of ethos and pathos enhances emotional attachment, followed by donation intention. Contrary to an expectation, however, logos was not significantly related to emotional attachment. Creators of Internet personal media and MCN providers should focus on the different effects of rhetorical factors and pay attention to the role of emotional attachment to encourage user donation.

The emergence of the internet technology and SNS has increased the information flow and has changed the way people to communicate from one-way to two-way communication. Users not only consume and share the information, they also can create and share it among their friends across the social network service. It also changes the Social Media behavior to become one of the most important communication tools which also includes Social TV. Social TV is a form which people can watch a TV program and at the same share any information or its content with friends through Social media. Social News is getting popular and also known as a Participatory Social Media. It creates influences on user interest through Internet to represent society issues and creates news credibility based on user's reputation. However, the conventional platforms in news services only focus on the news recommendation domain. Recent development in SNS has changed this landscape to allow user to share and disseminate the news. Conventional platform does not provide any special way for news to be share. Currently, Social News Service only allows user to access the entire news. Nonetheless, they cannot access partial of the contents which related to users interest. For example user only have interested to a partial of the news and share the content, it is still hard for them to do so. In worst cases users might understand the news in different context. To solve this, Social News Service must provide a method to provide additional information. For example, Yovisto known as an academic video searching service provided time dependent metadata from the video. User can search and watch partial of video content according to time dependent metadata. They also can share content with a friend in social media. Yovisto applies a method to divide or synchronize a video based whenever the slides presentation is changed to another page. However, we are not able to employs this method on news video since the news video is not incorporating with any power point slides presentation. Segmentation method is required to separate the news video and to creating time dependent metadata. In this work, In this paper, a time dependent metadata-based framework is proposed to segment news contents and to provide time dependent metadata so that user can use context information to communicate with their friends. The transcript of the news is divided by using the proposed story segmentation method. We provide a tag to represent the entire content of the news. And provide the sub tag to indicate the segmented news which includes the starting time of the news. The time dependent metadata helps user to track the news information. It also allows them to leave a comment on each segment of the news. User also may share the news based on time metadata as segmented news or as a whole. Therefore, it helps the user to understand the shared news. To demonstrate the performance, we evaluate the story segmentation accuracy and also the tag generation. For this purpose, we measured accuracy of the story segmentation through semantic similarity and compared to the benchmark algorithm. Experimental results show that the proposed method outperforms benchmark algorithms in terms of the accuracy of story segmentation. It is important to note that sub tag accuracy is the most important as a part of the proposed framework to share the specific news context with others. To extract a more accurate sub tags, we have created stop word list that is not related to the content of the news such as name of the anchor or reporter. And we applied to framework. We have analyzed the accuracy of tags and sub tags which represent the context of news. From the analysis, it seems that proposed framework is helpful to users for sharing their opinions with context information in Social media and Social news.
