Trust and Online Social Networks

Social media is becoming and increasingly essential source of information that people use when making entertainment, political, and economic decisions. The classical sender-receiver and gatekeeper concepts of mass media are blurred as with social media every individual can become the creator of news that is discussed world-wide. Identifying trustworthy sources of information is important to social media users and it is an interesting and complex research questions. Part of the complexity is due to the data being huge, e.g., millions of messages, multi-lingual, highly variable across time and space, and time-sensitive.  New metrics, theories, and algorithms are needed to reason about trust in this environment, and to identify trusted information providers.  This session is centered on the following two questions:  How is trust established or broken in social media networks? How can we measure trust?
