Noam Kantor has been awarded a Marshall Scholarship
$news$	Published Date: 2016-11-30 Noam Kantor, an Emory University Scholar, has been named one of 32 nationwide recipients of the prestigious Marshall Scholarship. The goal of the Marshall Scholarship is to "finance young Americans of high ability to study for a graduate degree in the United Kingdom" and "strengthen the enduring relationship between the British and American peoples, their governments and their institutions". Noam is a senior undergraduate and will earn his dual bachelor’s and master’s degree in mathematics this spring; Noam will use the Marshall to earn a second master’s degree in math, studying number theory, from Oxford, before applying to graduate programs in mathematics.

Emory System Ranks First in Live Question Answering Challenge
$news$	Published Date: 2016-11-21 A question answering system, developed at Emory by a Ph.D. student Denis Savenkov, was ranked first in the LiveQA challenge, as announced at the 2016 Text Retrieval Conference (TREC 2016) on November 2016. The goal of the LiveQA challenge was to quickly answer questions posted by real users on a popular website, Yahoo Answers. This task pushes the limits of automatic question answering and information retrieval, as these questions express complex information needs that people chose to ask to a community, rather than turning to existing search engines. On top of it, the systems had to respond within a minute, bringing additional realism to the challenge. 26 systems from North America, Europe, Asia and Australia participated in the LiveQA challenge. The system responses were judged by the assessors from the National Institute of Science and Technology (NIST), that co-organized the challenge together with Yahoo Labs and Emory University. An Emory system, developed by Denis Savenkov of the Emory IR Lab, was ranked 1st among all of the participants. Denis is advised by Prof. Eugene Agichtein, and is a Ph.D. student in the Emory Computer Science & Informatics program. The top-scoring Emory system, CRQA, uses many sources of information to automatically generate a set of candidate responses, and score them using state-of-the-art machine learning models. CRQA operates as a "cyborg", combining the best of human intuition with automatic responses, by using a novel real-time crowdsourcing module to obtain additional feedback from real human workers, while still returning answers quickly. The CRQA system was able to provide acceptable answers to more than 60% of the user questions, and perfectly answered over 22% of the questions, according to the quality judgments provided by professional NIST assessors. More details about the Emory system are published in a paper titled "CRQA: Crowd-powered Real-time Automated Question Answering System", by Denis Savenkov and Eugene Agichtein, in proceedings of the AAAI Human Computation conference (HCOMP 2016). Despite significant advances in automated question answering, the LiveQA challenge demonstrated that a large gap still remains between automatic question answering systems and good human answers, ~50% of which were judged to be excellent, compared to only 22% provided by the top-ranked Emory system. The LiveQA challenge will run again in 2017. More details about the challenge are available at www.trec-liveqa.org.

Students Attend Grace Hopper Conference
$news$	Published Date: 2016-11-03 In October, twenty-one undergraduates and graduates represented The Department of Math and Computer Science at this year’s Grace Hopper Celebration of Women in Computing in Houston, Texas. The gathering was attended by 15,000 people unified by their motivation to support diversity in STEM fields. Jamelia Mays, a junior at Emory majoring in Math and Computer Science: “The Grace Hopper Conference was an amazing experience. This year was my first time attending and I was overwhelmed by the sheer number of women in technology that surrounded me from the moment I walked into the door. I learned so much from other students and engineers that I wouldn't have learned anywhere else. I am so grateful to have an even bigger support system of strong, inspiring, successful women to reach out to.” Learn more about the conference here.
