# Konkani Figurative Language Corpus (Idioms + Metaphors) 📚

**A dataset for idiom and metaphor classification in low-resource Konkani.**

---

## 🚀 Overview

This dataset extends the Konidioms Corpus (Shaikh et al., 2024) by adding metaphor annotations. It supports binary classification for both idioms and metaphors in Konkani, a multi-script language spoken by approximately 2.5 million people.

---

## 📊 Dataset Description

- **Language**: Konkani (Devanagari script)
- **Tasks**: 
  - Idiom Detection (Yes/No)
  - Metaphor Detection (Yes/No)
- **Format**: CSV with the following columns:
  - `id`: Sentence identifier
  - `sentence`: The Konkani sentence
  - `idiom`: `Yes` or `No`
  - `metaphor`: `Yes` or `No`
  - `split`: `train` or `test`
- **Size**:
  - 6,520 idiom-annotated sentences
  - 500 metaphor-annotated sentences
- **Splits**:
  - ~80% training
  - ~20% testing

---

## 🎯 Motivation

Konkani is a low-resource language with significant dialect and script variation. Figurative language, particularly metaphors, remains understudied. This dataset allows exploration of idioms and metaphors within a single corpus and supports efficient modeling efforts in underrepresented languages.

## 🧰 Baseline Model

From the paper: [Pruning for Performance: Efficient Idiom and Metaphor Classification in Low-Resource Konkani Using mBERT](https://arxiv.org/abs/2506.02005)

- **Model**: mBERT + BiLSTM
- **Optimization**: Gradient-based attention head pruning
- **Result**: Comparable performance to full mBERT with fewer parameters

---

## 🧪 Example Use Cases

- Figurative language analysis in Indic languages
- Efficient multilingual transformer training
- Evaluation of pruning strategies for model compression
- Cross-lingual transfer learning in low-resource contexts
