| # CQADupstackAndroidRetrieval — BEIR, unified schema | |
| A normalised copy of the dataset behind the `mteb` task **`CQADupstackAndroidRetrieval`**, 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` int64 -> int32 | |
| - kept 7 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 | |
| ## Load it | |
| ```python | |
| from datasets import load_dataset | |
| queries = load_dataset("Hyukkyu/beir-cqadupstack-android", "queries", split="test") | |
| corpus = load_dataset("Hyukkyu/beir-cqadupstack-android", "corpus", split="test") | |
| qrels = load_dataset("Hyukkyu/beir-cqadupstack-android", "qrels", split="test") | |
| ``` | |
