What is Twitter

Citizens' engagement on local governments' Facebook sites. An empirical analysis: The impact of different media and content types in Western Europe

An expectation-confirmation model of continuance intention to use mobile instant messaging

Many public organizations are opening their data to the general public and embracing social media in order to stimulate innovation. These developments have resulted in the rise of new, infomediary business models, positioned between open data providers and users. Yet the variation among types of infomediary business models is little understood. The aim of this article is to contribute to the understanding of the diversity of existing infomediary business models that are driven by open data and social media. Cases presenting different modes of open data utilization in the Netherlands are investigated and compared. Six types of business models are identified: single-purpose apps, interactive apps, information aggregators, comparison models, open data repositories, and service platforms. The investigated cases differ in their levels of access to raw data and in how much they stimulate dialogue between different stakeholders involved in open data publication and use. Apps often are easy to use and provide predefined views on data, whereas service platforms provide comprehensive functionality but are more difficult to use. In the various business models, social media is sometimes used for rating and discussion purposes, but it is rarely used for stimulating dialogue or as input to policy making. Hybrid business models were identified in which both public and private organizations contribute to value creation. Distinguishing between different types of open data users was found to be critical in explaining different business models.

Infomediary Business Models for Connecting Open Data Providers and Users

Social media are becoming an important intermediary for interaction between governments, governments and citizens, and governmental agencies and businesses. This is due to the unique characteristics of social media: openness, participation, and sharing. However, despite rapid adoption, a growing concern and skepticism regarding the use of social media exists in the public sector. The purpose of this study is to investigate empirically the risks and benefits of social media use by public agencies. For this purpose, a research model was developed and tested in a survey of 289 government sector employees from six South Korean government research institutes. We found that both risks (i.e., social risk, time, psychological risks, and privacy concern) and benefits (i.e., social connectivity, social involvement, information attainment, and entertainment) significantly affect public sector employees' satisfaction with and intention to use social media. However, the effect of the benefits on users' satisfaction was stronger than the risks. The results of the study have important implications for researchers and policy makers.

Social Media Risks and Benefits: A Public Sector Perspective

– This study aims to explore Twitter use by Korea's central government by classifying the government's Twitter-based networking strategies into government-to-citizen (G2C) and government-to-government (G2G) strategies , – The study investigates the nature of social media interactions and networking strategies in the Korean government by extracting tweets, follower/following relationships, and hyperlinks for 32 ministries Network patterns and networking strategies are reviewed through descriptive statistical analysis and social network analysis to map the government's Twitter activity , – The results indicate that the government's direct networking strategy targeting citizens does not necessarily motivate their participation in the government's social media activities but that it plays an instrumental role in reinforcing G2G relationships , – This study investigates the social media use patterns (eg network properties and co-link analyses) and strategies (eg the reciprocity of relationships and content-push strategies) in the context of G2C and G2G relationships in Korea's public sector

From e-government to social government: Twitter use by Korea's central government

This study examines Twitter use by the central government in Korea and the federal government in the USA by employing the webometric technique to extract their Twitter activity (basic Twitter statistics such as the numbers of followers, followings, and Tweets) and the social network analysis technique to map the relationship between their Twitter accounts and the direction of outlinks in their Tweets. The results of the initial analysis indicate some differences in Twitter strategies between the two governments. For example, Korean ministries were well connected through a dense network, engaged in collective cooperation, and retweeted common content to reinforce their collective agendas regardless of their main administrative functions, whereas US government departments were less collective and more individualistic and retweeted those messages that specifically fit the purpose of each department. In addition, the results for outlinks indicate that US government departments preferred private sources of inf...

Social media communication strategies of government agencies: Twitter use in Korea and the USA

BACKGROUND
A knowledge gap exists between the list of required actions and the action plan for countering cancer misinformation on social media. Little attention has been paid to a social media strategy for disseminating factual information while also disrupting misinformation on social media networks.


OBJECTIVE
The aim of this study was to, first, identify the spread structure of cancer misinformation on YouTube. We asked the question, "How do YouTube videos play an important role in spreading information about the self-administration of anthelmintics for dogs as a cancer medicine for humans?" Second, the study aimed to suggest an action strategy for disrupting misinformation diffusion on YouTube by exploiting the network logic of YouTube information flow and the recommendation system. We asked the question, "What would be a feasible and effective strategy to block cancer misinformation diffusion on YouTube?"


METHODS
The study used the YouTube case of the self-administration of anthelmintics for dogs as an alternative cancer medicine in South Korea. We gathered Korean YouTube videos about the self-administration of fenbendazole. Using the YouTube application programming interface for the query "fenbendazole," 702 videos from 227 channels were compiled. Then, videos with at least 50,000 views, uploaded between September 2019 and September 2020, were selected from the collection, resulting in 90 videos. Finally, 10 recommended videos for each of the 90 videos were compiled, totaling 573 videos. Social network visualization for the recommended videos was used to identify three intervention strategies for disrupting the YouTube misinformation network.


RESULTS
The study found evidence of complex contagion by human and machine recommendation systems. By exposing stakeholders to multiple information sources on fenbendazole self-administration and by linking them through a recommendation algorithm, YouTube has become the perfect infrastructure for reinforcing the belief that fenbendazole can cure cancer, despite government warnings about the risks and dangers of self-administration.


CONCLUSIONS
Health authorities should upload pertinent information through multiple channels and should exploit the existing YouTube recommendation algorithm to disrupt the misinformation network. Considering the viewing habits of patients and caregivers, the direct use of YouTube hospital channels is more effective than the indirect use of YouTube news media channels or government channels that report public announcements and statements. Reinforcing through multiple channels is the key.

Understanding the Social Mechanism of Cancer Misinformation Spread on YouTube and Lessons Learned: Infodemiological Study

This study examined Internet discourse on inter-regional co-prosperity. In particular, the study is interested in the co-prosperity between the Daegu-Gyeongbuk regions. The Internet discourse was searched through a set of four keywords: co-prosperity, economy, business attraction, and cultural tourism. The study also conducted sentiment analysis of YouTube comments to determine how the Internet responds to co-prosperity topics. The findings of the analysis are as follows. First, Internet discourse related to co-prosperity has evolved from abstract concepts to concrete cooperative measures and policy contents. Second, the discussion of co-prosperity has moved from outside help or support to self-sustaining innate motivation. Finally, YouTube sentiment analysis showed that if co-prosperity efforts between regions are promoted through concrete policy contents, it becomes easier to gain positive responses from citizens and lead a positive policy drive. In this regard, a study on Internet discourse is a useful means to detect citizens' response to inter-regional co-prosperity.

A Study of Internet Discussion on Inter-regional co-prosperity : Focusing on Daegu-Gyeongbuk Regions

This study examines the dynamics of the overlap and shift of opinion-editorial (op-ed) guest columnists in a single news market. While previous studies have explored the diversity of op-ed columnists within an individual newspaper, we have investigated the dynamics through the ecological framework of market competition. The purpose of this article is to see how newspapers recruit op-ed columnists from the social pool, based on their position in the market. To explore this aspect efficiently, we have chosen the largely self-enclosed newspaper market of South Korea and analyzed longitudinal data on 7 national newspapers in that region. We expected that the market positions and political ideologies would delineate the movement and diversity of columnists. We found that the market leaders of the newspaper industry tended to achieve a diversity of op-ed columnists by actively recruiting them from other newspapers. However, the alignment of political ideology was still crucial in the recruitment.
