HVMap Dataset
HVMap Dataset is a BEIR/MTEB-style text-retrieval benchmark package for federated vector retrieval across heterogeneous vector databases. It contains the retrieval corpus, mixed-domain queries, and qrels used by the HVMap cross-domain benchmark described in Federated Vector Retrieval across Heterogeneous VectorDBs.
Repository Layout
| Path | Description |
|---|---|
data/corpus/*.jsonl |
Search corpus shards derived from FIQA, BioASQ, SciDocs, and SciFact. |
data/queries/*.jsonl |
Mixed-domain benchmark queries. queries.jsonl is the combined 2,000-query file. |
data/qrels/*.jsonl |
Qrels in JSONL form. qrels.jsonl is the combined qrels file. |
data/qrels/*.tsv |
BEIR/TREC-style qrels with header query-id corpus-id score. |
metadata/dataset_manifest.json |
Counts, source-corpus metadata, and validation summary. |
Corpus
The corpus uses retrieval-standard fields:
| Field | Description |
|---|---|
_id |
Corpus document id. IDs are prefixed by domain, for example fin-, bio-, or sci-. |
title |
Source title, empty when not provided by the upstream corpus. |
text |
Searchable document text. |
source_dataset |
Local source dataset name: fiqa, bioasq, scidocs, or scifact. |
domain |
finance, biomedical, or science. |
Corpus size:
| Source dataset | Domain | Documents |
|---|---|---|
fiqa |
finance | 57,638 |
bioasq |
biomedical | 40,221 |
scidocs |
science | 25,657 |
scifact |
science | 5,183 |
| Total | 128,699 |
Upstream metadata fields that are not needed for retrieval are not included in the corpus JSONL; the corpus is normalized to id/title/text plus source/domain fields.
Queries and Qrels
The benchmark contains 2,000 mixed-domain queries:
| Dataset alias | Qrels source | Queries | Qrels rows |
|---|---|---|---|
fin_bio |
fin_bio_qrels.pickle |
500 | 2,960 |
bio_sci |
bio_sci_qrels.pickle |
500 | 2,786 |
fin_sci |
fin_sci_qrels.pickle |
500 | 2,706 |
fin_bio_sci |
fin_bio_sci_qrels.pickle |
500 | 4,414 |
| Total | 2,000 | 12,866 |
The qrels files use binary score values. Each query-document link from the
source qrels is represented with score = 1.
Qrels JSONL fields:
| Field | Description |
|---|---|
qrel_id |
Stable row id in the form {query_id}:{document_index}. |
query_id |
Query id used in this package, such as fin_bio:0000. |
corpus_id |
Corpus document id matching the _id field in data/corpus/*.jsonl. |
score |
Binary qrels score. |
dataset_alias |
Mixed-domain dataset alias. |
qrels_name |
Source qrels pickle filename. |
query_index |
Zero-based query index within the source qrels file. |
document_index |
Zero-based linked-document position within that query. |
Loading
Load the full benchmark:
from datasets import load_dataset
dataset = load_dataset("snu-aidas/HVMap-dataset", "all")
corpus = dataset["corpus"]
queries = dataset["queries"]
qrels = dataset["qrels"]
Load only one mixed-domain benchmark subset:
fin_bio = load_dataset("snu-aidas/HVMap-dataset", "fin_bio")
fin_bio_corpus = fin_bio["corpus"]
fin_bio_queries = fin_bio["queries"]
fin_bio_qrels = fin_bio["qrels"]
Available mixed-domain configs:
fin_bio: finance + biomedical corpus,fin_bioqueries/qrelsbio_sci: biomedical + science corpus,bio_sciqueries/qrelsfin_sci: finance + science corpus,fin_sciqueries/qrelsfin_bio_sci: finance + biomedical + science corpus,fin_bio_sciqueries/qrels
Load only a domain corpus:
finance = load_dataset("snu-aidas/HVMap-dataset", "finance", split="corpus")
biomedical = load_dataset("snu-aidas/HVMap-dataset", "biomedical", split="corpus")
science = load_dataset("snu-aidas/HVMap-dataset", "science", split="corpus")
The science config reads both scidocs and scifact corpus shards. The
underlying files remain separate in the repository.
Load only combined queries or qrels:
queries = load_dataset("snu-aidas/HVMap-dataset", "queries", split="queries")
qrels = load_dataset("snu-aidas/HVMap-dataset", "qrels", split="qrels")
For BEIR-style evaluation, download data/corpus/*.jsonl,
data/queries/queries.jsonl, and data/qrels/qrels.tsv. The TSV qrels files
use the conventional query-id, corpus-id, score header.
Source Data and Licenses
This dataset contains mixed third-party source text. The repository metadata
therefore uses license: other; users must comply with the applicable upstream
licenses and attribution requirements.
| Upstream source | Domain role | License metadata |
|---|---|---|
BeIR/fiqa |
Financial | cc-by-sa-4.0 |
rag-datasets/rag-mini-bioasq |
Biomedical | cc-by-2.5 |
BeIR/scidocs |
Scientific | cc-by-sa-4.0 |

The HVMap mixed-domain queries and qrels packaging are project-generated. The embedded source corpus text remains subject to upstream dataset licenses.
Validation
Cross-Domain Benchmark Validation
Validation consists of a human relevance assessment and two independent LLM-based consistency checks. For the human assessment, 100 queries were randomly sampled from each of the four cross-domain settings, yielding 400 queries and 2,564 associated query-document pairs. Three authors independently judged whether each document was relevant to its corresponding query.
| Validation source | # Queries | # Pairs | Relevant ratio |
|---|---|---|---|
| Annotator 1 | 400 | 2,564 | 99.0% |
| Annotator 2 | 400 | 2,564 | 98.8% |
| Annotator 3 | 400 | 2,564 | 98.3% |
| Mean pairwise agreement: 99.1%; Fleiss’ κ: 0.64 | |||
| Claude Opus 4.8 | 2,000 | 12,866 | 94.5% |
| Codex GPT-5.5 | 2,000 | 12,866 | 93.3% |
The human judgments yielded a mean pairwise agreement of 99.1% and a Fleiss’ κ of 0.64; the difference from the raw agreement reflects the highly imbalanced label distribution. As a secondary full-benchmark consistency check, Claude Opus 4.8 (max reasoning effort) and Codex GPT-5.5 (extra-high reasoning effort) independently judged all 12,866 query-document pairs across 2,000 queries. They judged 94.5% and 93.3% of the pairs as relevant, respectively.
Corpus and Qrels Integrity
Before packaging, every qrels-linked corpus_id was checked against the
normalized corpus IDs included in this release.
- Corpus document IDs are unique: 128,699 unique IDs.
- All qrels-linked document IDs are present in the corpus.
- Missing qrels document count: 0.
- Qrels rows: 12,866.
Intended Use
This dataset is intended for research on text retrieval, text ranking, federated vector retrieval, heterogeneous vectorDB federation, cross-domain retrieval, and benchmark construction.
Limitations
- The qrels use binary scores.
- Some upstream corpus records have empty
textfields in the local source corpus. These records are retained to preserve corpus id compatibility. - The corpus is normalized for retrieval and omits heavy upstream metadata that is not required for retrieval experiments.
Citation
If you use this dataset, cite the HVMap paper and the upstream corpora listed above. A formal BibTeX entry can be added once the HVMap paper metadata is finalized.
