Ganging Up on Big Data: Computer-Intermediated Collaborative Analysis

Understanding complex situations is difficult. Intelligence analysis has long been the work of teams including subject matter specialists. Today collaborative analysis takes place in the context of big data", where information comes from a variety of human, communications, and sensor sources. Understanding the big picture is both about how analysts interact and combine their insights together and with how they engage with data at scale. In this paper we consider opportunities for next generation analysis systems for teams, focusing on the computer-intermediated functions that support and coordinate analytic activities around big data.
