Enhancing the creation, consumption and dissemination of trustworthy knowledge in the Web and social media

The Web has become a vast repository of information and knowledge about a wide range of topics and real-world events. There are a growing number of sites, ranging from question answering sites and online communities to microblogs, where knowledge is crowdsourced and it also the crowd who curates the contributed knowledge.  These sites also contain an ever-growing number of unverified stories of questionable origin. There is a growing need for computational methods to understand, predict and enhance the creation, consumption and dissemination of trustworthy knowledge.
