POLAR (Polemics in Online Language and Automated Recognition) is a 24-month collaborative research project funded within the YUFE Alliance and hosted at Université Sorbonne Nouvelle.

The project investigates how online speakers express stance and controversy through covert or overt discursive strategies (e.g., distancing, alignment, rhetorical questions or remarks), and how such strategies can be identified qualitatively and then detected automatically.


Research aims

🔍
Identify & describe

Distance and controversy markers functioning as polemic markers, and model how they operate in context.

🤖
Explore & automate

Tool-assisted approaches — automatic annotation, detection, clustering and text mining — to refine automatic decision-making for polemic detection.


Method in a nutshell

Qualitative

Manual identification of polemical strategies across linguistic, abstract (e.g., irony/metaphor), and argumentation levels.

Quantitative & Computational

Annotation, machine learning / NLP, and evaluation on large-scale social media data.
