Open Entity

Introduced by Eunsol Choi et al. in Ultra-Fine Entity Typing1 Jan 2018 archive 2025-07-28

The Open Entity dataset is a collection of about 6,000 sentences with fine-grained entity types annotations. The entity types are free-form noun phrases that describe appropriate types for the role the target entity plays in the sentence. Sentences were sampled from Gigaword, OntoNotes and web articles. On average each sentence has 5 labels.

12 shown of 12 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 35. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
