Sujet :
Participatory democracy platforms (Make, Decidim, Cap Collectif, Consul) enable thousands of citizens to propose and discuss ideas for public policies. However, the large volume of textual contributions produces severe information overload: citizens struggle to identify similar or opposing proposals, while decision-makers face difficulty in detecting consensus or disagreement.

Recent research at LIP6 has shown that Natural Language Processing (NLP) can detect argumentative relations between citizen proposals (equivalence, contradiction, neutrality). These relations can be structured into argumentative graphs, which help organize debates and improve navigation within large participatory datasets.

This internship aims to extend these ideas using Graph Retrieval-Augmented Generation (Graph-RAG). By combining graph-based retrieval with language generation, the project seeks to build intelligent tools capable of summarizing debates, identifying conflicting or redundant proposals, and assisting citizens in writing balanced contributions.
