NanoBIRCO
This dataset is a Nano-style retrieval dataset for HAKARI-bench.
NanoBIRCO contains 5 Nano retrieval splits derived from BIRCO. Each split keeps up to 200 eligible queries and up to 10000 corpus documents, with exact duplicate query and document text removed where the generator records that policy.
Usage
from datasets import load_dataset
dataset_id = "hakari-bench/NanoBIRCO"
split = "NanoBIRCOArguAna"
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_idandtextqueries: queries with_idandtextqrels: positive relevance labels withquery-idandcorpus-idbm25: BM25 candidate lists withquery-idandcorpus-idsharrier_oss_v1_270m: dense candidate lists frommicrosoft/harrier-oss-v1-270mreranking_hybrid: RRF candidate lists built frombm25andharrier_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 examplewordseg@ja.harrier_oss_v1_270m: dense top-500 frommicrosoft/harrier-oss-v1-270m. In tables this is shown asDense; Dense meansmicrosoft/harrier-oss-v1-270mwith theweb_search_queryprompt for queries and cosine similarity over normalized embeddings.reranking_hybrid: RRF overbm25andharrier_oss_v1_270musingrrf_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.
