Personalized Jargon Identification for Enhanced Interdisciplinary Communication (2024.naacl-long)

Copied to clipboard

Challenge: Identifying and translating scientific jargon for individual researchers could speed up research, but current methods of jaron identification rely on corpus-level familiarity indicators rather than modeling researcher-specific needs.
Approach: They collect over 10K term familiarity annotations from 11 computer science researchers and investigate supervised and prompt-based methods to predict individual jargon familiarity.
