Northeast Languages Test Set

A curated test set of 500 deduplicated sentences per language for evaluating language models on Northeast Indian languages.

Languages

This dataset contains test data for 9 Northeast Indian languages:

Assamese (asm) - 500 sentences
Garo (grt) - 500 sentences
Khasi (kha) - 500 sentences
Kokborok (trp) - 500 sentences
Meitei (mni) - 500 sentences
Mizo (lus) - 500 sentences
Naga (nag) - 500 sentences
Nyishi (njz) - 500 sentences
Pnar (pbv) - 500 sentences

Total: 4,500 sentences

Dataset Construction

All test sentences were:

Extracted from newer corpora not present in NE-BERT training data
Deduplicated against the training corpus
Randomly sampled to ensure diversity

Usage

from datasets import load_dataset

# Load all languages
dataset = load_dataset("MWirelabs/northeast-languages-test-set")

# Load specific language
khasi_test = load_dataset("MWirelabs/northeast-languages-test-set", split="khasi")

Evaluation

This test set was used in the NE-BERT paper for perplexity evaluation.
