Data Curation at Scale

Professor Renée J. Miller

Data curation seeks to support all the processes necessary to manage and maintain value in data over its lifecycle. Curation includes the process of understanding the origins of data, how it was created, cleaned, or integrated, as well as data discovery. In Toronto's Big Data Curation Lab, we are studying how to scale important data curation tasks.  Among these, data integration and data discovery are perhaps the most important ways to add value to data.  In our iBench project, we are striving to raise the bar in empirical evaluation of data integration, data exchange, and schema mapping systems by providing a metadata generator that can create large, realistic scenarios to test both the scalability and functionality of systems.

In complementary research, we are investigating the challenges of curating open data.  In this talk, I will briefly describe our LinkedCT system, a curated linked open data system of clinical drug trials.  I will conclude the talk with some interesting challenges we have observed in creating internet scale data management solutions for open data.
