Trade News Semantic Duplicates (URNO)

Dataset for detecting semantic duplicates in international trade/economic news, built as part of a Master's thesis (ВКР, ИТМО).

Pairs of news articles are labeled using the URNO scheme — a four-way diagnostic taxonomy that distinguishes structurally different types of negatives:

Label	Meaning
D	Duplicate — same trade event, same information
U	Update — same event, new data or development (hard negative)
R	Related — different but similar events, e.g. same sector (hard negative)
N	Not related — different topics/events
O	Out of scope — non-trade content

binary_label = 1 for D, 0 for all others.

Configurations

goldset — Gold Standard (2,250 pairs)

100% human-annotated. Used as the evaluation benchmark. Label distribution: D=54%, U=24%, N=19%, R=2%, O=1%. LLM ↔ Human agreement: 98.98%.

silverset — Silver Set (4,591 pairs)

LLM-annotated (DeepSeek) with train/validation splits. Used for fine-tuning duplicate detection models.

Usage

from datasets import load_dataset

# Gold standard (evaluation)
gold = load_dataset("timerlanmukhtarov/trade-news-datasets", "goldset")

# Silver set (fine-tuning)
silver = load_dataset("timerlanmukhtarov/trade-news-datasets", "silverset")
silver["train"][0]

Source corpus

86,913 articles from 250+ multilingual news sources (EN/RU/PT/FR). Articles were embedded with BAAI/bge-m3, clustered via agglomerative clustering, then pairs were sampled per URNO category and annotated.
