+# CEMRC Romanian NER MRC Dataset
+
+This dataset repository contains MRC-style JSONL conversions for Romanian NER datasets used in the CEMRC thesis experiments.
+
+Included datasets: **ronec, legalnero, simonero**.
+
+## Format
+
+Split files are stored as `parquet` files under one folder per source dataset.
+
+Each row contains:
+
+- `example_id`
+- `source_dataset`
+- `source_hf_dataset`
+- `split`
+- `context_tokens`
+- `context`
+- `question`
+- `entity_type`
+- `answers.text`
+- `answers.answer_start`
+- `answer_word_spans`
+- `has_answer`
+- `n_answers`
+
+## Generation Settings
+
+- query style: `descriptive`
+- query sampling: `fixed`
+- train negatives: `all`
+- negative ratio: `3.0`
+- seed: `42`
+
+## Split Sizes
+
+- **ronec** — train: 135000, validation: 19950, test: 30000
+- **legalnero** — train: 37760, validation: 4830, test: 4535
+- **simonero** — train: 14988, validation: 1772, test: 1964
+
+Detailed split metadata is available in `splits_info.json`.
+
+## Notes
+
+The original datasets retain their own licenses and citation requirements. This repository provides an MRC-formatted derivative for reproducibility of the CEMRC thesis experiments.
