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.
