Dear Researchers,
We are excited to invite you to participate in the *PolyHope Shared Task at IberLEF 2025*, a unique challenge focused on analyzing the expression of hope in social media texts. Hope is a fundamental human emotion influencing decision-making, yet its nuanced nature—especially when masked by sarcasm—presents significant challenges for Natural Language Processing (NLP) systems. This year, the task expands its scope to Spanish texts, emphasizing hope as an expectation alongside its existing English counterpart.
*Task Description*
The goal of PolyHope is to classify social media texts based on their expression of hope, with two subtasks available:
1. *Binary Hope Speech Detection (Subtask 1.a: English, Subtask 1.b: Spanish)* - *Hope:* Texts conveying hope, expectation, or desire. - *Not Hope:* Texts that do not express any hopeful sentiment. 2. *Multiclass Hope Speech Detection (Subtask 2.a: English, Subtask 2.b: Spanish)* - *Generalized Hope:* Broad optimism without specific targets. - *Realistic Hope:* Hope grounded in plausible outcomes. - *Unrealistic Hope:* Expressions of hope for unlikely outcomes. - *Not Hope:* Texts without hopeful sentiment. - *Sarcasm:* Texts that mimic hope but are sarcastic in nature.
This task aims to promote research in *inclusive language technologies*, enhance the *psychological and linguistic understanding* of hope, and develop *multilingual NLP models* capable of detecting nuanced sentiment and sarcasm.
