TASK DESCRIPTION:
*
*
The task focuses on detection and classification of Persuasion
Techniques in 5 Slavic languages — Bulgarian, Polish, Croatian, Slovene
and Russian — in two types of texts: (a) parliamentary debates on
hotly-contested topics, and (b) social media posts, related to the
spread of disinformation. The task has two subtasks:
1.
Subtask 1: Detection — Given a text and a list of fragment offsets,
determine for each fragment whether it contains one or more
persuasion techniques, from a given taxonomy of persuasion techniques,
2.
Subtask 2: Classification —Given a text and a list of fragment
offsets, determine for each fragment which persuasion techniques are
employed therein.
We use a rich taxonomy with 25 persuasion techniques: Name-calling or
labelling, Guilt by association, Casting doubt, Appeal to hypocrisy,
Questioning the reputation, Flag waiving, Appeal to authority, Appeal to
popularity, Appeal to fear and prejudice, Appeal to values, Strawman,
Whataboutism, Red herring, Appeal to pity, Causal oversimplification,
False dilemma or no choice, Consequential oversimplification, False
equivalence, Slogans, Conversation killer, Appeal to time, Loaded
language, Obfuscation-Intentional vagueness-confusion, Exaggeration or
minimization, Repetition.
Subtask 1 is a binary classification task, whereas Subtask 2 is a
multi-class multi-label classification task. The text fragments
correspond to paragraphs.
