# Dataset Card for Luxembourgish Entailment-based Topic classification via Zero-shot learning (LETZ)

## Dataset Summary
The datasets for **L**uxembourgish **E**ntailment-based **T**opic classification via **Z**ero-shot learning (**LETZ**) can be used to adapt language models to zero-shot classification in Luxembourgish. It leverages data from the [*Luxembourg Online Dictionary*](https://lod.lu) to provide relevant topic classification examples in Luxembourgish. The LETZ datasets were created to address the limitations of using Natural Language Inference (NLI) datasets for zero-shot classification in low-resource languages. Specifically, they aim to improve topic classification performance by providing more relevant and accessible data through dictionary entries.

## Columns in the Dataset

Each dataset includes the following columns:

* **Text**: The Luxembourgish sentence or phrase.
* **Label**: The potentially associated topic label.
* **Class**: A binary indicator where “1” denotes relevance (entailment) and “0” denotes irrelevance (non-entailment).
