ChandassuMeterClassification

Single-label Telugu poetic meter (chandassu / type) classification for PoetryMTEB, derived from the Chandassu corpus (Kaggle / Mendeley / Hugging Face; local Chandassu_Dataset.csv).

Dataset Card

Item	Description
Source	Kaggle; Mendeley Data (DOI: 10.17632/46wrt7v53c.1); Hugging Face; paper arXiv:2510.01233
Languages	Telugu (te)
Size	train=3721; test=930 (no validation)
Classes	8 meters (type field)
Splits	Stratified ≈ 80% / 19% by meter, with cross-dataset anti-leakage vs PoetryMTEB/Padyam2GadyamMeterClassification
License	MIT (same as upstream)
Evaluation metrics	Classification on embeddings: accuracy, macro/weighted F1

Cross-dataset split constraint

Relative to PoetryMTEB/Padyam2GadyamMeterClassification:

1. Chandassu train does not contain poems that appear in Padyam test
2. Chandassu test does not contain poems that appear in Padyam train

Matching uses whitespace-normalized poem text. Forced assignments:
Padyam-train overlaps → Chandassu train (20 poems);
Padyam-test overlaps → Chandassu test (6 poems).

Verified after split: chandassu_train ∩ pady_test = 0, chandassu_test ∩ pady_train = 0.

Construction method

1. Load local Chandassu_Dataset.csv / upstream Chandassu.
2. Load PoetryMTEB/Padyam2GadyamMeterClassification train/test poems; force overlapping Chandassu rows into compatible splits (anti-leakage).
3. Stratified train/test split of remaining rows by type (seed=42).
4. Map type → contiguous label ids (frequency-descending).

How to load

from datasets import load_dataset

ds = load_dataset("PoetryMTEB/ChandassuMeterClassification")
print(ds["test"][0]["label_name"], ds["test"][0]["poem"][:60])
