IMPOLS at EVALITA 2026: Overview of the IMPOLS Task

This paper describes the IMPOLS task presented at EVALITA 2026 competition. The task regards the automatic detection and classification of implicit contents in political speeches, specifically focusing on the uses of implicit expressions that are potentially manipulative. The task is divided in three subtasks: (1) implicit content detection, (2) implicit classification (implicature and presupposition), and (3) implicature type classification. IMPOLS is monolingual (Italian) multimodal task: provided data included audio and transcription of speech excerpts, along with some discourse metadata. Two teams participated at IMPOLS, obtaining a macro F1 score of 0.95 on subtask 1, 0.88 on subtask 2, and 0.64 on subtask 3.
