Online social networks (OSN) are increasingly being used as places where communities gather to exchange information, form opinions, collaborate in response to events like disasters or even social movements like the Arab Spring or Occupy Wall Street. OSNs both serve as places that bring communities together and as places where new communities are formed. These networks enable large scale and fast communication that has not been possible in the past. As a result, the networks are an ever changing medium of exchange.

Participants face many challenges, particularly with respect to trust. Trust is a crucial component of social relationships. It allows individuals to share privileged information or take actions that involve risk. When can information found on social media be trusted? Information typically travels very fast and becomes common wisdom before any trusted authorities can verify it. Who can be trusted to accomplish specific tasks? What are some important cues in determining trust? Can these cues be manipulated? How can online social networks be protected against malicious activities?

This workshop aims to bring together researchers who study the role trust plays in online social networks. Our aim is to study trust from various perspectives, bridging cutting edge research in social science, psychology, cognitive science and computer science to develop a new understanding of trust in today's highly connected communities. We invite papers that study trust from a broad perspective and develop tools to understand, measure or enhance trust.

Papers describing work in progress, interdisciplinary approaches to trust are especially suited for this workshop. Short papers of 4 pages and long papers of 8 pages maximum will both be accepted. All papers must use the IEEE two-column template. All papers will be peer-reviewed by at least three reviewers from the selected program committee. Papers will be selected based on their originality, timeliness, significance, relevance, and clarity of presentation. Authors should illustrate that their papers represent new previously unpublished work. Accepted papers will be published as part of the ASONAM proceedings. Note that at least one author of accepted papers needs to register and attend the workshop.
