North American Computational Linguistics Olympiad hosted by Emory University
Published Date: 2015-02-06
On Jan 29, 2015, the Department of Mathematics and Computer Science and the Program in Linguistics and hosted the North American Computational Linguistics Olympiad. NACLO is a contest in which high school students solve problems in computational linguistics. Winners of the competition can participate in an invitational round, which can ultimately lead to participation in an international competition. This year Emory joined other top universities (52 in all) in hosting the event, including Carnegie Mellon, Columbia, Cornell, Dartmouth, Georgetown, Johns Hopkins, MIT, Stanford, Michigan, Penn, and Yale. Emory was the only school in the southeast to serve as a host. Invitations were sent to over 70 high school academic bowl coaches in Georgia, ultimately yielding 23 participants, and putting Emory in the top third of schools in the nation in terms of number of participants. The event was held in the Winship Ballroom, and participants received a mug (with an Emory logo), a campus tour, and lunch at Cox Hall. Emory undergraduate students from Computer Science and Linguistics Science helped to run the event. The main organizers of the event was Jinho Choi from Computer Science and Phillip Wolff from Linguistics.

Math/CS Welcomes New Faculty Member Jinho Choi
news Published Date: 2014-08-06
Jinho Choi is an assistant professor in the Department of Mathematics and Computer Science at Emory University. He obtained a Ph.D. in Computer Science and Cognitive Science from the University of Colorado Boulder in 2012. Jinho Choi has been active in research on natural language processing; especially, on the optimization of low-level NLP (e.g., part-of-speech tagging, dependency parsing, semantic role labeling) for robustness on various data and scalability on large data. He has developed an open source project called ClearNLP, providing NLP components with state-of-the-art accuracy and speed, which has been widely used for both academic and industrial research. His current research focuses on the development of NLP components for different domains (e.g., social media, medical data) and the applications of these NLP components for end-user systems such as question-answering, information extraction, dialog management, etc. He is also interested in interdisciplinary research where NLP can enhance researches in other areas.
