LiveChatBench (v1.1)

Korean → English translation benchmark built from Korean live-streaming chat messages. Each row pairs a Korean chat message with an English reference translation. Where a message relies on streaming slang, community jargon, or a streamer/game name, a short background note explains the term; it is an empty string when no note is needed.

Fields

Field	Type	Description
background	string	Optional glossary note for slang/terms in the message ("" when not given)
ko	string	Source Korean chat message
en	string	English reference translation

Stats

• 1,000 sentence pairs (test split)
• 728 rows with a non-empty background, 272 rows with ""

Usage

from datasets import load_dataset

ds = load_dataset("naruto-soop/LiveChatBench", split="test")
print(ds[0])
# {'background': '챌섭: 챌린저스 월드 (메이플스토리 서버)',
#  'ko': '챌섭이라 뭐가없는걸요..',
#  'en': 'Since it’s the Challengers World server, there’s hardly anything.'}
