BanglaRhet: Benchmarking Transformer Models for Rhetorical and Persuasion Detection in Bangla Political Speech

Political speech persuades long before it informs. BanglaRhet is the first systematic benchmark for detecting how that persuasion works in Bangla, a language spoken by over 240 million people yet still underserved by NLP research.

Built a manually annotated corpus of 30,289 Bangla political speech segments from Motamot, Prothom Alo, and Manab Zamin. Formulated two classification tasks: rhetorical technique detection (contrast, repetition, exaggeration, metaphor, rhetorical questions) and persuasion technique detection (blame assignment, call to action, unity call, moral, emotional and logical appeals). Four transformer models were benchmarked, with BanglaBERT setting the strongest baselines.

Interests

Outside coursework I spend most of my time exploring new technology and reading AI and NLP research, with a particular interest in making language tools work for low-resource languages like Bangla.
