| # 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. |
