Multimedia Vaccine Informatics System for Discovering Vaccine Hesitancy in Social Media
2021/03 Guided by (a) theories of communication; (b) models of vaccine hesitancy; as well as (c) novel Artificial
Intelligence techniques, enabled by Large Language Models (LLMs) and Large Multimedia Models (LMM) we
process tens of millions of social media postings collected from Facebook, Instagram and X/Twitter to
discover how hesitancy towards the COVID-19, the Human Papillomavirus and Influenza vaccines is framed in
social media discourse. 
Automatic discovery and processing of EEG cohorts from clinical records
2014/06–2019/10 The primary goal of this proposal is to enable comparative research by automatically uncovering clinical knowledge from a vast big data archive of clinical EEG and EMR data collected over the past 12 years at Temple University Hospital. We  develop a proof-of-concept based on the discovery of patient cohorts and provide an annotated big data archive (including a semantic index). This resource will greatly increase accessibility for non-experts in neuroscience, bioengineering and medical informatics, and demonstrate the transformative potential of mining the staggering wealth of biomedical knowledge available in hospital EMRs.

Prof Calls Jeopardy! Match a Computing Milestone
Prof  Calls Jeopardy! Match a Computing Milestone When an IBM supercomputer named Watson takes on human contestants on the quiz show Jeopardy! this week, it will represent the latest triumph of advances that could one day enable people to interact much more naturally with computers, according to a UT Dallas expert in human-machine interaction. “This is a milestone because Watson will compete directly against humans, and moreover against the champions of Jeopardy!” said Dr. Sanda Harabagiu, a leader in the field of human-computer interaction for more than a decade. “This is important, and it’s a more realistic gauge than simply comparing a system to search engines.” It’s hard enough to create a system that can interact via spoken language fast enough to compete on Jeopardy!, but Harabagiu and her collaborators in the University’s Human Language Technology Research Institute are already working on even more complex human-computer interactions.
Computer Science Professor Earns Distinguished Paper Award
Computer Science Professor Earns Distinguished Paper Award Travis Goodwin BS'11, MS'13, a computer science PhD student at UT Dallas, and Dr. Sanda Harabagiu, professor of computer science and Research Initiation Chair in the Erik Jonsson School of Engineering and Computer Science, received the Homer R. Warner Award at the 2017 American Medical Informatics Association’s (AMIA) Annual Symposium.

The award recognizes a symposium paper that best describes approaches to improving computerized information acquisition, knowledge data acquisition and management, and experimental results documenting the value of these approaches.
Human Language Technology Research Institute Established at The University of Texas at Dallas
RICHARDSON, Texas (Feb. 25, 2002) - The University of Texas at Dallas (UTD) today announced that it has established a research institute aimed at advancing the understanding and uses of natural language processing, a science that has grabbed the attention of federal government intelligence agencies in the wake of Sept. 11.

The technology, which utilizes sophisticated software tools, has the potential to help security personnel simultaneously screen and analyze millions of voice and text communications in an attempt to uncover terrorist or other criminal activities. Other possible uses include customer support applications in many lines of business.

The research, new at UTD, will be carried out at the newly established Human Language Technology Research Institute in the Erik Jonsson School of Engineering and Computer Science. The effort will be headed by Dr. Sanda Harabagiu, director of the institute and an associate professor of computer science in the Jonsson School. Harabagiu also holds the Jonsson School Research Initiation Chair Professorship.
