Despite calls to conceptualize credibility as three separate concepts—source credibility, message credibility, and media credibility—there exists no scale that exclusively measures message credibil...

Measuring Message Credibility: Construction and Validation of an Exclusive Scale

Trust has long been considered an important factor that influences people’s relationship with news. However, the increase in the volume of information available online, together with the emergence of new tools and services that act as intermediaries and enable interactivity around the news, may have changed this relationship. Using Reuters Institute Digital News Report survey data (N = 21,524), this study explores the impact of individual trust in the news media on source preferences and online news participation behaviour, in particular sharing and commenting, across 11 countries. The results show that those with low levels of trust tend to prefer non-mainstream news sources like social media, blogs, and digital-born providers, and are more likely to engage in various forms of online news participation. These associations tend to be strongest in northern European countries, but are weaker elsewhere. Seeking alternative views and attempting to validate the credibility of news may be among the motivations ...

The Impact of Trust in the News Media on Online News Consumption and Participation

Enter the Robot Journalist: Users' perceptions of automated content

This study investigates a range of traditional and technological factors that contribute to credibility perceptions for three categories of online news sources. These sources include mainstream (usatoday.com, nytimes.com), independent (thedrudgereport.com, axisoflogic.com), and index-type (news.google.com, yahoo.news.com) websites. While traditional dimensions of credibility remain influential, results suggest that the hypertextuality of index-type online news sources is of particular importance. Multimediality and interactivity did not influence credibility perceptions. These results support the perspective that online media differ based on credibility and users' perceptions are in part based on the technological affordances of media. A major contribution of this research lies in the empirical demonstration of the relationships between technological characteristics of various online news sources and subsequent credibility assessments. © 2012 Wiley Periodicals, Inc.

Exploring Online News Credibility: The Relative Influence of Traditional and Technological Factors

The purpose of this study was to investigate where students turn for course-related assignments, whether an ordered pattern could be described in terms of which sources students turn to and how students evaluated the information they chose to use. Data were drawn from open-ended questionnaires ( n  = 282). Semantic network analysis was conducted using CATPAC, artificial neural network software. Results verify previous findings that students turn to the Internet before the library, but a deeper investigation revealed different preferences for study versus project-related research. Specifically, using search engines or Wikipedia was a pre-stage, rather than a final destination, for project work. Interestingly, students were relatively confident in their abilities to discern courses using the Internet. Recommendations for promoting information literacy, as well as recommendations for improving library resource use, are included.

Convenience or credibility? A study of college student online research behaviors

This article analyzes the inaugural addresses of two Korean presidents using mixed methods of social network-oriented and socio-psychological linguistic text analyses. The analyses determined that former President Roh frequently used words relating to international affairs and politics, while current President Lee used rhetoric related to the economic perspective, emphasizing the construction of an advanced nation. The former was popularly known for his progressive (leftwing) policies while the latter emphasized his conservative and neo-liberal political stances during the presidential campaigns. As the first political-message analysis of its kind in Korea, this study has broad implications for inaugural-address research as an analytical tool to help understand not only the relationship between rhetorical substance and style but also the characteristics of presidential administrations’ political and social viewpoints.

Textual analysis of a political message: the inaugural addresses of two Korean presidents

In this study, we examined the structure of the international hyperlink network as a global communication system at two different points in time (2003 and 2009). Research was carried out on the web-based network linking country code top-level domains (ccTLDs) that represent countries, using hyperlink connectivity by the means of network analysis. The results indicate that the 2009 international hyperlink network was completely interconnected. G7 countries and Spain were at the centre of the network. At the periphery were poorer countries from Africa, Asia, and Latin America. In addition, several regional clusters based on geography, language and culture emerged. A comparison of the 2003 and 2009 results showed that the level of centralization and diversification among semi-peripheral countries increased. We discuss the results from the perspective of world-systems theory. We propose methodological procedures to overcome potential bias in international hyperlink data.

Structural changes in the 2003–2009 global hyperlink network

Purpose – The purpose of this paper is to discover the primary components of credibility of three types of online newspapers and how the credibility of news differs by type.Design/methodology/approach – The paper participants were recruited at a large north‐eastern US university. All items of credibility scales were measured using seven‐point Likert‐type scales. For each of the three credibility scales, the mean was computed and the scales were analysed for similarities and differences. The scales were factor analysed to determine their underlying dimensions.Findings – Three factors (expertise, trustworthiness, and attractiveness) were common to the three types, but the different factor structure of each type was identified. The result of multiple comparisons shows that the differences between all three types of online newspapers were significant. Also the summated scores of the mainstream type were the highest on most items. However, the summated score of the index type of online newspaper was the highes...
