# CQADupstackProgrammersRetrieval — BEIR, unified schema
A normalised copy of the dataset behind the `mteb` task **`CQADupstackProgrammersRetrieval`**, one of the tasks of the [BEIR](https://github.com/beir-cellar/beir) benchmark as `mteb` defines it (a member of the aggregate task `CQADupstackRetrieval`). Same queries, documents
and relevance judgements as the benchmark evaluates — reshaped into one strict schema shared by every dataset
in this collection.

## 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, newline, or control-character normalisation
- cast `qrels.score` double -> int32
- kept 3 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`
## Load it
```python
from datasets import load_dataset
queries = load_dataset("Hyukkyu/beir-cqadupstack-programmers", "queries", split="test")
corpus = load_dataset("Hyukkyu/beir-cqadupstack-programmers", "corpus", split="test")
qrels = load_dataset("Hyukkyu/beir-cqadupstack-programmers", "qrels", split="test")
```
