| # NanoMIRACL |
|
|
| This dataset is a Nano-style retrieval dataset for [HAKARI-bench](https://github.com/hakari-bench/hakari-bench). |
|
|
| NanoMIRACL is a compact multilingual benchmark derived from MIRACL. Each language split evaluates monolingual retrieval of Wikipedia passages for natural-language questions. |
|
|
| This rebuild uses `hotchpotch/miracl-hf-unified` dev queries at source revision `21ad00eb467639e927b5badb7c49f4947c6c24ca`. For each sampled query, it preserves all source positive passages and expands the split-local corpus to 10,000 documents using source negatives as hard-negative candidates plus deterministic random fill. |
|
|
| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| dataset_id = "hakari-bench/NanoMIRACL" |
| split = "ar" |
| |
| queries = load_dataset(dataset_id, "queries", split=split) |
| corpus = load_dataset(dataset_id, "corpus", split=split) |
| qrels = load_dataset(dataset_id, "qrels", split=split) |
| reranking_candidates = load_dataset(dataset_id, "reranking_hybrid", split=split) |
| ``` |
|
|
| ## Data Layout |
|
|
| This dataset uses six Hugging Face Datasets configs: |
|
|
| - `corpus`: documents with `_id` and `text` |
| - `queries`: queries with `_id` and `text` |
| - `qrels`: positive relevance labels with `query-id` and `corpus-id` |
| - `bm25`: BM25 candidate lists with `query-id` and `corpus-ids` |
| - `harrier_oss_v1_270m`: dense candidate lists from `microsoft/harrier-oss-v1-270m` |
| - `reranking_hybrid`: RRF candidate lists built from `bm25` and `harrier_oss_v1_270m` |
|
|
| Each config has the same Nano split names. |
|
|
| ## Candidate Construction |
|
|
| - `bm25`: local BM25 top-500 with automatic language-aware tokenization. The resolved tokenizer is shown in the Candidate Quality table, for example `wordseg@ja`. |
| - `harrier_oss_v1_270m`: dense top-500 from `microsoft/harrier-oss-v1-270m`. In tables this is shown as `Dense`; Dense means `microsoft/harrier-oss-v1-270m` with the `web_search_query` prompt for queries and cosine similarity over normalized embeddings. |
| - `reranking_hybrid`: RRF over `bm25` and `harrier_oss_v1_270m` using `rrf_k=100`, keeping the RRF top-100. |
|
|
| Safeguard means rank 101 is appended only when RRF top-100 contains no qrels-positive document. |
|
|
| ## Split Statistics |
|
|
| Length statistics are character counts computed with `len(str(text))`. |

|
| ## Candidate Quality |
|
|
| `nDCG@10` and `Recall@100` are computed from the included candidate rankings against the included qrels, then reported as 0-100 scores such as `52.45`. `Recall@100` uses only the top 100 candidates; an optional rank-101 safeguard positive is not counted in `Recall@100`. |
|
|
| Dense means `microsoft/harrier-oss-v1-270m` with the `web_search_query` prompt and cosine similarity. |
