|
**Task** |
|
|
- Binary predicate-level event factuality (one row per predicate). |
|
|
|
|
|
**Labels** |
|
|
- `label`: `0=false`, `1=true` |
|
|
- `label_rule`: `single`, `agree`, `na_other`, `tie_conf4_vs0`, `tie_conf4_vs1`, `tie_conf4_vs2` |
|
|
|
|
|
**Preprocessing** |
|
|
- Filter `Keep=True`. |
|
|
- Aggregate up to 2 annotations per predicate; resolve ties using `label_rule`; drop unresolved cases. |
