A Review on Credibility Perception of Online Information

Credibility generally regards one's belief in the truth due to an initial impression of a subject. Different types of credibility assessment are taken into account by online readers as a process to decide whether a trust relationship would concur between them and the source of the information based on the quality of the information and the reputation or quality of a source. A large body of literature exists on online credibility evaluation, with particular emphasis on online social media (OSM), specifically Twitter. In this paper we will provide the background knowledge on the theoretical part of information credibility, discuss the reader's credibility perception behaviours and factors that have an impact on credibility judgements. We then followed up by a description of credibility evaluation methodologies and summarise the research gaps regarding information credibility perceptions and propose some future work in the information credibility perception research area.
