The ability to collect, integrate, and analyze data from large number of diverse data sources has increased the amount of data collected and processed by individual organizations on the order of several tens to hundreds of TB. This data can be efficiently utilized for better decision making, improved business intelligence, as well as for enabling new knowledge and services.

Collaborative generation and utilization of large quantities of data, either through crowdsourcing or through efforts of different organizations and groups creates notable research opportunities. The potential benefits of Collaborative Big Data, as well as new and unexpected challenges are still emerging. Managing, processing, and making sense of this data pose new challenges in storage, networking, database management, data mining, knowledge discovery, information security and privacy.

C-Big 2012 brings together researchers and practitioners from around the world to share their experiences on creating, managing, and handling Collaborative Big Data and its benefits.

The authors of selected papers from the workshop will be invited to submit extended versions of the papers to a special issue in Elsevier's Information Systems journal.
