| ## Event Factuality (It Happened / UDS-IH2) |

|
|
| **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. |
