+# parser_dataset
+
+Parser training and evaluation data for multi-hop QA with long concatenated document contexts.
+
+Derived from [HotpotQA](https://hotpotqa.github.io/) and [2WikiMultihopQA](https://github.com/Alab-NII/2wikimultihop).
+
+## Contents
+
+| Path | Split | Samples | Notes |
+| --- | --- | --- | --- |
+| `train/hotpotqa_train_process_emb-select_llm-unable.parquet` | train | HotpotQA processed train | VERL / `ParserRLHFDataset` format |
+| `2wiki_val/eval_{N}.json` | eval | 128 per file | 2WikiMultihopQA, `N` documents per example |
+| `hqa_val/eval_{N}.json` | eval | 128 per file | HotpotQA, `N` documents per example |
+
+`N` ∈ `{50, 100, 200, 400, 800, 1600, 3200, 6400}`.
+
+## Load
+
+```python
+from datasets import load_dataset
+
+train = load_dataset("inNexus/parser_dataset", "train", split="train")
+hqa_50 = load_dataset("inNexus/parser_dataset", "hqa_val", split="eval_50")
+wiki_6400 = load_dataset("inNexus/parser_dataset", "2wiki_val", split="eval_6400")
+```
+
+## Fields
+
+**Train parquet** (consumed by `ParserRLHFDataset`): `prompt`, `context`, `reward_model`, `data_source`.
+
+**Eval JSON**
+
+- `hqa_val`: `context`, `input`, `answers`, `num_docs`, `index`
+- `2wiki_val`: same as above, plus `is_ordered`, `is_reverse_ordered`, `min_distance`, `evidence_idx`, `level`, `type`, `id`
