DoveBench

A segment-level English→Chinese translation benchmark derived from the ViDove release corpus. DoveBench pairs each Chinese translation segment with an aligned English reference, packaged as a single JSONL so evaluation runs directly without per-file parsing.

Companion dataset for ViDove: A Translation Agent System with Multimodal Context and Memory-Augmented Reasoning (Lu et al., 2025).

from datasets import load_dataset

ds = load_dataset(
    "json",
    data_files="dovebench/dovebench.jsonl",
    split="train",
)
row = next(r for r in ds if r["video_id"] == "sc2/13_07")
print(row)
# → {'video_id': 'sc2/13_07', 'youtube_id': 'n-Dx7MLqFqY', 'idx': 0,
#    'start': 0.0, 'end': 3.55,
#    'zh_text': '欢迎来到这一场的SC2专业比赛',

Plain Python

import json
with open("dovebench/dovebench.jsonl") as f:
    rows = [json.loads(line) for line in f]

# Group by video
from collections import defaultdict
by_video = defaultdict(list)
for r in rows:
    by_video[r["video_id"]].append(r)
