FewEvent (mneb/casie format)

FewEvent (Deng et al., WSDM 2020) converted into the mneb json_structures event-extraction format. FewEvent annotates two tasks — event detection (triggers) and event argument extraction (roles); it has no entity or relation layer, so each record's output carries only json_structures. Char offsets are end-exclusive (input[start:end] == text). One record = one sentence = one event. Single test split per config.

The two configs (split by what annotation is present)

• trigger_and_args (default) — ~16.4k records that carry a clean trigger and typed arguments (33 event types, 35 roles). Supports both event detection and argument extraction.
• trigger_only — ~65k records with a trigger but no arguments (arguments: []). Supports event detection only.

The split criterion is the annotation itself (does the instance have clean role-typed arguments?), i.e. which task it supports — not the raw data source. Provenance correlates but does not line up cleanly:

• trigger_and_args is essentially the human-annotated portion (ACE-2005 + TAC-KBP-2017).
• trigger_only is mostly the Freebase/Wikipedia distant-supervised portion, but also includes a few thousand ACE/KBP-origin instances that simply lack clean argument annotations (the raw enriched file was augmented unevenly). So these are named by task, not by source.

Provenance & license (please read before redistributing)

FewEvent was built from: ACE-2005 (LDC2006T06) + TAC-KBP-2017 Event Track (both human-annotated, LDC-licensed / restricted), and Freebase + Wikipedia auto-labeled data (distant supervision; Wikipedia text is CC-BY-SA, Freebase was CC-BY). The upstream GitHub release (231sm/Low_Resource_KBP) ships no license file. The trigger_and_args half therefore contains LDC-derived text whose public redistribution may be restricted; downstream users should ensure they hold the appropriate ACE-2005 / TAC-KBP licenses. The trigger_only half's distant-supervised labels are noisy — treat as eval-only, and do not treat absence of an event as ground truth.
