Latest NLP Research Derives Insight from Growing Volume of Digital Text

New NLP research from Georgia Tech is allowing for patterns to be uncovered in this text and broaden the understanding of how to build better computer applications that derive value from written language.

Georgia Tech researchers are presenting their latest work at the annual conference of the North American Chapter of the Association for Computational Linguistics (NAACL 2022), taking place this week, July 10-15. NAACL provides a regional focus for members of the Association for Computational Linguistics (ACL) in North America as well as in Central and South America and promotes cooperation and information exchange among related scientific and professional societies.

“Recent advances in natural language processing ­­­­– especially around big models – have enabled successful applications,” said Diyi Yang, assistant professor in the School of Interactive Computing and researcher in NLP. “At the same time, we see a growing amount of evidence and concern toward the negative aspects of NLP systems, such as the bias and fragility exhibited by these models, as well as the lack of input from users.”

Yang’s work in computational social science and NLP focuses on how to understand human communication in social context and build socially aware language technologies to support human-to-human and human-computer interaction.

Her SALT Lab has accrued an impressive number of innovations in the field over the past eight months, starting with research presented at last November’s EMNLP conference. SALTers, as they are called, led Georgia Tech to become the top global contributor in computational social science and cultural analytics at that venue. The 60th Meeting of the ACL in Dublin followed in May with multiple SALT studies, including a best paper. Yang’s group has six papers at this week’s NAACL.

“We hope to build NLP systems that are more user centric, more robust, and more aware of human factors,” said Yang. “Our NAACL works are in this direction, covering robustness, toxicity detection, and generalization to new settings.”

Yang’s aspirations for the field are shared by her Tech peers, who have work in the following tracks at NAACL:

  • Ethics, Bias, Fairness
  • Information Extraction
  • Information Retrieval
  • Interpretability and Analysis of Models for NLP
  • Machine Learning
  • Machine Learning for NLP
  • Semantics: Sentence-level Semantics and Textual Inference
