CSE's Li, Jimenez Win Awards at ACM SIGMOD

Friday, May 26, 2017

CSE associate professor Chengkai Li and his undergraduate student, Damian Jimenez, won awards at the Association of Computing Machinery (ACM) SIGMOD conference held in Chicago May 14-19.

Chengkai LiLi and his team won one of four Most Reproducible Paper Awards for their submission, “Generating Preview Tables for Entity Graphs.” The reproducibility test submission and verification took place after last year’s conference and the awards were given during this year’s conference. The authors of the paper include CSE Ph.D. graduate Ning Yan and current Ph.D. students Sona Hasani and Abolfazl Asudeh.

According to Li, the computing community is working to promote independent verification of published research results to ensure that research money is being used for successful projects.

“The committee was able to conveniently reproduce the results reported in the paper using the source code we provided, thus verifying and establishing the results,” Li said. “I am thrilled by this award. My team has always gone the extra mile to make our research accessible and accountable, and I am glad it is paying off. In most cases it is very difficult, if not impossible, to verify the results in computer science papers. I think the community is moving in the right direction to change the status quo.”

Damian Jimenez, a computer science student who will begin his doctoral studies in the fall, received the First Runner-Up award in the SIGMOD Student Research Competition. His submission titled, “ClaimBuster: Toward Building an Automated Fact-checking System,” went through a three-stage selection process: abstract paper, poster presentation, and oral presentation. ClaimBuster is an online tool designed by Li’s team that helps journalists fact-check statements made by politicians in real time.

“Damian has been instrumental in my group and has made significant contributions to the project. I look forward to more excellent achievements by him during his Ph.D. study,” Li said.

Hong Jiang, chair of the Computer Science and Engineering Department, expressed his appreciation for Li and Jimenez’ efforts.

 “I am very proud of the achievements of Chengkai and his team, as well as Damian, in winning these awards in the flagship data management conference in the world. This helps increase our profile and visibility in the data management research and industry communities,” he said.

The annual ACM SIGMOD/PODS conference is a leading international forum for database researchers, practitioners, developers, and users to explore cutting-edge ideas and results, and to exchange techniques, tools, and experiences. The conference includes a fascinating technical program with research and industrial talks, tutorials, demos, and focused workshops. It also hosts a poster session to learn about innovative technology, an industrial exhibition to meet companies and publishers, and a careers-in-industry panel with representatives from leading companies.
