Integrating Data, Integrating Science
Zachary Ives , University of Pennsylvania
Data is the lifeblood of modern policy-making, decision-making, and scientific discovery. Hence it should be no surprise that “big data” analysis is in high demand. Yet in a tremendous number of settings, “big data” is more conceptual than real. The relevant data is actually spread across a plethora of Web pages, databases, spreadsheets, and PDFs, some of which may not even be publicly available, and many of which use different notation and make different baseline assumptions. How do we put all of this data together in order to reason about relationships and make decisions or discoveries? This requires both technical solutions as well as changes in culture. Science makes an excellent venue for studying both the technical and nontechnical aspects of large scale collaborative data sharing. In this talk will describe our research on the Q System, a scalable, incremental, community-driven platform for integrating data as needed, using techniques such as algorithmic matching, machine learning, and collaborative filtering. Then I will outline our efforts to bring these ideas to the neuro-science community, in the IEEG.org platform, and the lessons learned in incentivizing data sharing. I will finish by describing our vision for where community-scale data sharing is headed. Joint work with Allen Zhepeng Yan, Nan Zheng, Partha Talukdar, Cong Yu, Fernando Pereira, Sudipto Guha, Brian Litt, Joost Wagenaar, Greg Worrell, Ben Brinkmann.
