+# QuoraRetrieval — BEIR, unified schema
 
-# BEIR QUORA Dataset (Migrated)
-
-This is a migrated version of BeIR/quora that is compatible with datasets library 4.0.0+.
-
-## Dataset Description
-
-This dataset contains the quora dataset from the BEIR benchmark, converted from the old script-based format to Parquet format.
-
-## Dataset Structure
-
-### Queries
+A normalised copy of the dataset behind the `mteb` task **`QuoraRetrieval`**, one of the tasks of the [BEIR](https://github.com/beir-cellar/beir) benchmark as `mteb` defines it. Same queries, documents
+and relevance judgements as the benchmark evaluates — reshaped into one strict schema shared by every dataset
+in this collection.
 
-- **Split 'queries'**: 15,000 examples
-  - Features: ['_id', 'text', 'metadata']
+|  |  |
+|---|---|
+| Source | [`mteb/quora`](https://huggingface.co/datasets/mteb/quora/tree/e4e08e0b7dbe3c8700f0daef558ff32256715259) @ `e4e08e0b7dbe` (the revision pinned in `mteb`) |
+| Domain · languages | duplicate-question · eng |
+| Queries / documents / qrels (all splits) | 15,000 / 522,931 / 23,301 |
+| Qrels per query | min 1 · mean 1.567 · max 75 |
+| Score values | 1 ×15,675 |
+| Layout | `queries` · `corpus` · `qrels`, split `test`; `queries`/`qrels` also carry `dev` — one shared corpus |
+| Splits | `qrels`: dev, test · `queries`: dev, test |
+| License | `cc-by-sa-4.0` |
 
-- **Total examples**: 15,000
+## Schema
 
+| config | columns | rules |
+|---|---|---|
+| `queries` | `id: string`, `text: string` | ids unique and non-empty; every query has ≥ 1 qrel |
+| `corpus` | `id: string`, `title: string`, `text: string` | `title` is always present (`""` when the source has none) |
+| `qrels` | `query-id: string`, `corpus-id: string`, `score: int32` | referential integrity to both tables; no duplicate pairs; no floats |
 
-### Corpus
+Files are Parquet, sorted by id, zstd-compressed, sharded at 500 MB. Every rule above is enforced by a validator
+before publishing; `provenance.json` records the source file hashes, what changed, and the output file hashes.
 
-- **Split 'corpus'**: 522,931 examples
-  - Features: ['_id', 'title', 'text', 'metadata']
+## What changed from the source
 
-- **Total examples**: 522,931
+- `dev`: dropped 10,000 queries that have no qrels in this split (mteb does the same at load time)
+- `test`: dropped 5,000 queries that have no qrels in this split (mteb does the same at load time)
+- cast `qrels.score` double -> int32
+- kept 568 documents whose text is identical to another document's — a property of the source; note that models embed such documents identically and retrieval ties among them are broken by corpus order
+- renamed `_id` → `id`
+- renamed source splits (`queries`←`queries/queries`, `corpus`←`corpus/corpus`) to `test`
 
-
-## Usage
+## Load it
 
 ```python
 from datasets import load_dataset
-
-# Load queries (split: queries)
-queries = load_dataset("Hyukkyu/beir-quora", "queries", split="queries")
-
-# Load corpus (split: corpus)
-corpus = load_dataset("Hyukkyu/beir-quora", "corpus", split="corpus")
+queries = load_dataset("Hyukkyu/beir-quora", "queries", split="test")
+corpus  = load_dataset("Hyukkyu/beir-quora", "corpus", split="test")
+qrels   = load_dataset("Hyukkyu/beir-quora", "qrels", split="test")
 ```
 
+## Cross-check against the previous layout
 
-## Available Splits
-
-### Queries
-- `queries`: 15,000 examples
+This repo previously held the same dataset in BEIR's raw two-repo form (`Hyukkyu/beir-quora` + `Hyukkyu/beir-quora-qrels`; that layout is kept under the git tag `legacy-layout`). Before replacing it, the build was compared against it: corpus id set **identical** (522,931 documents); qrels rows per split `test` 15,675 = 15,675, `dev` 7,626 = 7,626.
 
-### Corpus
-- `corpus`: 522,931 examples
+## License and attribution
 
-## Original Dataset
+The data is redistributed under the source's terms — `cc-by-sa-4.0`. All credit belongs to the
+original authors; see the source repository and the references in `mteb`'s task metadata.
+This repository is an independent repackaging and is not affiliated with the RTEB or MTEB maintainers.
