Data Systems Group
The Data Systems Group builds innovative, high-impact platforms, systems, and applications for processing, managing, analyzing, and searching the vast collections of data that are integral to modern information societies – colloquially known as “big data” technologies. Our capabilities span the full spectrum from unstructured text collections to relational data, and everything in between including semi-structured sources such as time series, log data, graphs, and other data types. We work at multiple layers in the software stack, ranging from storage management and execution platforms to user-facing applications and studies of user behaviour. Our research tackles all phases of the information lifecycle, from ingest and cleaning to inference and decision support.
- David Toman and Grant Weddell won the 2016 Ray Reiter Best Paper Prize for their paper "On Referring Expressions in Query Answering over First Order Knowledge Bases" that was presented at the 15th International Conference on Principles of Knowledge Representation and Reasoning. The paper was co-authored with their long-time collaborator Alex Borgida of Rutgers University. (27 April 2016)

- Jaemyung Kim, Ken Salem, Khuzaima Daudjee, Ashraf Aboulnaga and Xin Pan received Best Paper Award at the 2015 ACM Symposium on Cloud Computing for their paper titled "Database High Availability Using SHADOW Systems" (5 September 2015).
- Lei Chen, Tamer Özsu and Vincent Oria were recognized with the Test-of-Time Award at the SIGMOD 2015 Conference in Melbourne, Australia. The award "recognizes the best paper from the SIGMOD proceedings 10 years prior ..., based on the criterion of identifying the paper that has had the most impact (research, products, methodology) over the intervening decade. " The winning paper was "Robust and Fast Similarity Search for Moving Object Trajectories," that appeared in the 2005 SIGMOD Proceedings. Lei Chen obtained his PhD from Waterloo in 2005 and Vincent Oria was Tamer's post-doc (9 June 2015).
- Alexey Karyakin (supervised by Ken Salem) is the winner of SIGMOD 2015 programming contest. Alexey was the only single person "team" -- the other finalists were all 2-3 person teams. Congratulations to Alexey and Ken (7 June 2015).
- Alexandra Roatiş has joined the group as a post-doctoral fellow as of January 2015. She obtained her PhD from Université Paris-Sud and Inria-Saclay and will be working with Ihab Ilyas.
- Olaf Hartig and Tamer Özsu gave a tutorial entitled "Linked Data Query Processing" at the 30th IEEE International Conference on Data Engineering (ICDE), which was held in Chicago 31 March-4 April 2014.
- David Toman's co-authored paper entitled "The Combined Approach to OBDA: Taming Role Hierarchies Using Filters" has won the Best Paper Award at the 12th International Conference on Semantic Web, which was held in Sydney, Australia, 21-25 October 2013.
- Xiufeng Liu has joined the group as a post-doctoral fellow as of 7 November 2013. He will be working with Lukasz Golab and Ihab Ilyas.
- Ashraf Aboulnaga (along with Shivnath Babu of Duke University) gave a tutorial on "Workload Management for Big Data Analytics" and Lukasz Golab (together with Theodore Johnson) gave a tutorial on "Data Stream Warehousing" at the 2013 ACM SIGMOD International Conference on Management of Data in New York City. Brief description of the tutorials are here and here. (28 June 2013)
- Three groups of database researchers have received grants from Canadian Foundation for Innovation for computing infrastructure to support our research projects. Tamer Özsu, Ian Munro and Khuzaima Daudjee have received $215,414 for the project "Cluster Computing Infrastructure for Scalable Big Data Management and Analysis," that will be used to establish a 64 multi-core node cluster. Ashraf Aboulnaga (along with Hans De Sterck of Applied Math) have obtained $159,158 for their project entitled, "Research Infrastructure for Computational Analytics on Big Data in the Cloud." The funding will be used to set up a 30 multi-core node Hadoop cluster. Tim Brecht, Bernard Wong, and Ken Salem received $198,359 for their project "A Testbed for Empirical Cloud Computing Research," to build a testbed for empirical cloud computing research. University's announcement is here. (6 June 2013)
