| # MAVEN-Arg (mneb event-extraction format) |
|
|
| MAVEN-Arg (Wang et al., ACL 2024) converted into the mneb `json_structures` |
| event-extraction format. It adds document-level, role-typed arguments to MAVEN events over |
| English Wikipedia documents. This is an independent document-level dataset intended for |
| `mneb/maven-arg`; it does not replace or modify the sentence-level, detection-only |
| `mneb/maven` dataset. |
|
|
| One record is one complete source document. Character offsets are end-exclusive and satisfy |
| `input[start:end] == text`. Event-type and argument-role strings are retained verbatim. |
| Every trigger mention in a source event cluster becomes an independent event entry and |
| inherits that cluster's full argument annotation. Events with no arguments are retained. |
|
|
| ## Splits and counts |
|
|
| | Split | Records | Source event clusters | Event entries | Source argument objects | Expanded argument spans | Event types | |
| |---|---:|---:|---:|---:|---:|---:| |
| | `train` | 2,913 | 64,923 | 70,775 | 190,479 | 380,830 | 162 | |
| | `validation` | 710 | 15,556 | 16,996 | 46,458 | 85,890 | 161 | |
| | **total** | **3,623** | **80,479** | **87,771** | **236,937** | **466,720** | **162** | |
|
|
| `validation` is the official raw `valid` split, renamed for consistency. The official test |
| split is excluded because it contains candidate event mentions but not the complete gold |
| event clusters and argument annotations required for this conversion. |
|
|
| ## Argument expansion |
|
|
| MAVEN-Arg attaches arguments to event clusters, not individual trigger mentions. Therefore, |
| each emitted trigger entry receives a copy of every argument on its source cluster. |
|
|
| - A direct `{content, offset}` argument becomes one `{role, text, start, end}` span. |
| - An `{entity_id}` argument is resolved against the document's entity coreference clusters |
| and expands to every mention span in the referenced cluster, each with the same role. |
| - Expansion preserves coreferent mention spans as event arguments, but does not encode the |
| fact that those mentions corefer. |
|
|
| All 94,922 entity references across train and validation resolve successfully. All source |
| trigger, direct-argument, and entity-mention offsets were checked against the original |
| document text; no annotation was silently dropped. |
|
|
| ## Deliberately omitted layers |
|
|
| This release contains event extraction only: trigger detection/classification plus event |
| argument extraction. It does not emit `entities` or `relations`, and in particular does not |
| emit entity or event coreference links. Source document/event/entity/mention ids, numeric |
| `type_id`, and `negative_triggers` are also omitted. |
|
|
| Entity and event coreference are outside the scope of this event-extraction release; no |
| cluster-to-pair conversion or coreference relation layer is planned here. |

|
| - `data/maven_arg_train.jsonl` and `data/maven_arg_validation.jsonl`: converted data. |
| - `maven_arg_label_role_summary.md`: event-label and argument-role counts. |
| - `maven_arg_vis.html`: deterministic sampled visualizer covering every event type in each |
| split where that type exists. |
| - Converter: `scripts/preprocess_maven_arg.py` in the source workspace. |
