pretty_name: Encyclopedic Completion Corpus

Encyclopedic completion corpus

Year-conditioned multi-word completion pairs covering science constants, people, geography, event dates, and arithmetic. Phrases are intentionally longer than a single entity token (typically 8–20 words).

Schema

{"prompt": "The atomic number of carbon is", "phrase": "6, placing carbon among the light nonmetals…", "year": 2013, "category": "science_constants", "source": "…"}

• year = knowledge cutoff for the shard (fact is valid at that cutoff)
• 1000000 rows per file in years/Y.jsonl for Y=2013..2024

Category mix (approx.)

category	share
science_constants	30%
event_dates	26%
people_founders	22%
geography	13%
math_arithmetic	9%

Sources

• Public encyclopedia-style timelines / biographies / geography
• Offline CC0-style static tables / formulas
• Synthetic arithmetic
• Optional Wikidata SPARQL (CC0)
