STELLA (Parquet)

telepix/STELLA 데이터셋의 HuggingFace-native Parquet 변환 버전입니다.

STELLA는 NASA Technical Reports Server (NTRS) 문서 기반 항공우주 도메인 Cross-lingual IR 벤치마크입니다.

Usage

from datasets import load_dataset

# Corpus (영어, 2.4M passages)
corpus = load_dataset("datalama/STELLA", "corpus", split="test")

# 한국어 쿼리
ko_queries = load_dataset("datalama/STELLA", "ko-queries", split="test")

# 한국어 qrels
ko_qrels = load_dataset("datalama/STELLA", "ko-qrels", split="test")

Configs

Config	Split	Rows	Description
corpus	test	2,405,044	영어 corpus (전 언어 공유)
{{lang}}-queries	test	1,000	언어별 쿼리 (7개 언어)
{{lang}}-qrels	test	1,000	언어별 relevance judgments

지원 언어: en, ko, fr, id, ja, th, zh

Schema

corpus: _id (str), title (str), text (str)

queries: _id (str), text (str)

qrels: query-id (str), corpus-id (str), score (int)

Cross-lingual Evaluation

STELLA는 비대칭 cross-lingual IR 벤치마크입니다:

• Corpus: 영어 전용 (NASA NTRS 문서)
• Queries: 영어 원본 + 6개 번역 언어
• 평가: 다국어 쿼리 → 영어 corpus 검색

쿼리 유형

• TCQ (Terminology Concordant Query): 기술 용어는 영어 유지, 설명만 번역
• TAQ (Terminology Agnostic Query): 전체를 타겟 언어로 완전 번역
