Assessing Online Media Content Trustworthiness, Relevance and Influence: an Introductory Survey

The increasing popularity of social media articles and microblogging systems is changing the way online information is produced: users are both content publishers and content consumers. Since information is produced and shared by common users, who usually have a limited domain knowledge, and due to an exponential growth of the available information, assessing online content trustworthiness is vital. Several works in the state of the art approach this issue and propose different models to estimate online content trustworthiness, content relevance and user influence. In this paper we investigate the most relevant research works in this domain, highlighting their common characteristics and peculiarities in terms of content source type, trust-related content features, trust evaluation methods and performance assessment techniques.
