# FreshStackRetrieval — RTEB open subset, unified schema

A normalised copy of the dataset behind the `mteb` task **`FreshStackRetrieval`**, one of the 17 open tasks in the
[RTEB(beta)](https://huggingface.co/blog/rteb) retrieval benchmark. Same queries, documents and relevance
judgements as the benchmark evaluates — reshaped into one strict schema shared by all 17.

|  |  |
|---|---|
| Source | [`embedding-benchmark/FreshStack_mteb`](https://huggingface.co/datasets/embedding-benchmark/FreshStack_mteb/tree/7a20df1abe4dafc46f93f9a7965bf9c6968bdf04) @ `7a20df1abe4d` (the revision pinned in `mteb`) |
| Domain · languages | code · eng |
| Queries / documents / qrels | 672 / 3,804 / 5,445 |
| Qrels per query | min 1 · mean 8.103 · max 35 |
| Score values | 1 ×5,445 |
| Layout | `queries` · `corpus` · `qrels`, split `test` |
| License | `mit` |

## 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 |

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.

## What changed from the source

- **byte-preserved** all text — no whitespace or newline normalisation (code dataset)
- added a `title` column filled with `""` (the source has none)
- cast `qrels.score` double -> int32
- renamed source splits (`queries`←`queries/queries`, `corpus`←`corpus/corpus`, `qrels`←`default/test`) to `test`

## Load it

```python
from datasets import load_dataset
queries = load_dataset("Hyukkyu/rteb-FreshStackRetrieval", "queries", split="test")
corpus  = load_dataset("Hyukkyu/rteb-FreshStackRetrieval", "corpus", split="test")
qrels   = load_dataset("Hyukkyu/rteb-FreshStackRetrieval", "qrels", split="test")
```
