+# MAVEN (mneb/casie format)
+
+MAVEN (Wang et al., EMNLP 2020) converted into the mneb `json_structures` event-extraction
+format. MAVEN is a massive general-domain event **detection** dataset — 168 event types over
+English Wikipedia documents. It is ED-only (no argument annotation), so each record's `output`
+carries only `json_structures`; every event's `arguments` is always `[]`. One record = one
+sentence. ALL sentences are kept, including event-less ones (`json_structures: {}`). Char
+offsets are end-exclusive (`input[start:end] == text`). Event-type strings are kept verbatim
+from the raw release.
+
+## Splits
+
+Official MAVEN document split:
+
+| Split | Docs | Sentences | Event mentions |
+|---|---:|---:|---:|
+| `train` | 2,913 | 32,431 | 77,993 |
+| `validation` | 710 | 8,042 | 18,904 |
+
+`validation` is MAVEN's raw `valid` split, renamed for naming consistency with the other
+converted datasets. The official `test` split is **not included**: its annotations are withheld
+for the CodaLab leaderboard, so it carries no gold event type or mention, only candidate
+triggers.
+
+## What is dropped from the raw release
+
+- The unlabeled `test` split.
+- `negative_triggers` and other candidate lists (explicitly-labeled non-events).
+- Event coreference: MAVEN groups multiple mentions under one event instance. The flat
+  per-sentence format used here cannot represent that grouping, so mentions become independent
+  trigger entries — mention counts are preserved exactly (nothing deduplicated or merged).
+- Numeric `type_id`s, mention/event ids, and the raw per-sentence token lists.
+
+## Token -> char note
+
+MAVEN's raw trigger spans are token indices into per-sentence token lists that are lossy
+(lowercased, rare words replaced by the literal string `unk`, PTB escapes for brackets/quotes).
+Triggers were re-anchored to the raw sentence text via greedy earliest-match case-insensitive
+alignment, trying PTB-variant candidates alongside the raw token, plus a neighbor-window
+fallback search for `unk`-substituted tokens. This recovered 100% of mentions: 0 drops, 0
+offset failures across both splits. The emitted trigger `text` is always the authoritative
+sentence slice (`input[start:end]`); it differs from the raw `trigger_word` in 795 (train) + 200
+(validation) cases, all case-only.
+
+## Provenance & license
+
+Source: THU-KEG/MAVEN-dataset (data distributed via Google Drive / Tsinghua Cloud), MIT
+license. Document text is drawn from English Wikipedia (CC BY-SA). The event schema is derived
+from FrameNet. Annotations are crowd-sourced.

+See `maven_label_summary.md` for the full 168-type inventory and per-split counts, and

+empty records per split).

+Counts computed from `processed_data/maven/maven_train.jsonl` (32,431 records) and
+`processed_data/maven/maven_validation.jsonl` (8,042 records), produced by
+`scripts/preprocess_maven.py` from **THU-KEG MAVEN** (Wang et al., EMNLP 2020; MIT license;
+English Wikipedia documents). The raw `valid` split is renamed `validation` for naming
+consistency with the other converted datasets; the official `test` split is unlabeled
+(carries only trigger `candidates`, no gold event type/mention) and is excluded.

+## Totals at a glance
+
+| Item | train | validation |
+|---|---:|---:|
+| Docs | 2,913 | 710 |
+| Records (sentences) | 32,431 | 8,042 |

+| Event types | 168 | 168 |
+
+## Build notes
+
+- Token -> char re-anchoring: greedy earliest case-insensitive match over the lossy
+  lowercased/`unk`-substituted raw token lists, with PTB-escape variants (`` `` ``, `''`,
+  `-LRB-`/`-RRB-`/`-LSB-`/`-RSB-`/`-LCB-`/`-RCB-`) tried alongside the raw token, plus a
+  neighbor-window fallback search for tokens the primary pass couldn't align (mostly the
+  `unk`-substituted ones).
+- 100% mention recovery: 0 mentions dropped, 0 offset failures across both splits.
+- `text_mismatch` (emitted `input[start:end]` slice differs from the raw `trigger_word`):
+  795 (train) + 200 (validation), **all case-only**; the emitted `text` is always the
+  authoritative sentence slice, never the raw (possibly lossy-cased) trigger word.
+
+## Dropped layers
+
+- Unlabeled official `test` split (no gold event type/mention, only `candidates`).
+- `negative_triggers` (explicitly-labeled non-events).
+- Event-coreference grouping: MAVEN groups multiple mentions under one event instance
+  (`id`); this layer is flattened — each mention becomes an independent per-sentence
+  trigger entry. Mention counts are preserved exactly (nothing deduplicated or merged).
+- Numeric `type_id`s, all raw `id`s (doc/event/mention), and the raw token lists
+  (superseded by char offsets).
