🌐 [ACL 2026] Query Embedding Mix Word-Mix Query Bundles

Tongyao Zhu, Chao-Ming Huang, and Min-Yen Kan

Study protocol: monolingual, word-mixed, and embedding-mixed query representations
_{This dataset packages the word-mix validation artifacts released with the ACL 2026 study.}

This dataset repository accompanies our ACL 2026 paper on mixed-language queries in multilingual dense retrieval. It packages the word-level code-mixed query bundles used in the appendix validation workflow, where word-mix is used as a probe to check whether embedding-level interpolation follows similar ratio trends.

The release covers four validation pairs:

EN-ZH, EN-VI, ZH-VI, HI-ID

Each pair is available as:

a Hugging Face configuration backed by a normalized Parquet file under data/
the original TSV bundle under raw/
per-pair metadata and checksums under metadata/

What You Will Find Here 📦

data/                  Parquet files for Hub loading and dataset viewer support
raw/                   Original TSV bundles copied from the released artifact directories
metadata/              Pair manifests, checksums, and staging summary
README.md              Dataset card tying this release back to the paper and code repo

Pair Summary 🔎

Pair	Config	Shared `qids-common`	Normalized rows
`en-zh`	`en-zh`	1484	28150
`en-vi`	`en-vi`	517	24998
`zh-vi`	`zh-vi`	242	14826
`hi-id`	`hi-id`	1391	18392

The Parquet files are the recommended interface for load_dataset(). The raw TSV bundles are preserved for provenance and direct inspection.

Load From Hugging Face 🤗

Load one pair as a Hugging Face dataset configuration:

from datasets import load_dataset

ds = load_dataset("hcm777/query-embedding-mix-word-mix", "en-zh", split="train")
common_band = ds.filter(lambda row: row["band_label"] == "40-60" and row["is_common_qid"])

Download the raw TSV bundle for a pair:

from huggingface_hub import snapshot_download

local_dir = snapshot_download(repo_id="hcm777/query-embedding-mix-word-mix", repo_type="dataset")

Row Schema

Each Parquet row corresponds to one (source_file, qid, text) entry from the raw bundle.

Field	Description
`pair`	Language-pair identifier such as `en-zh`.
`source_lang`	Source-side language code used in the pair label.
`target_lang`	Target-side language code used in the pair label.
`source_file`	Original TSV file name inside the raw bundle.
`variant`	`band` for mixed-ratio bands or `endpoint` for pure endpoints.
`subset`	`full` for full endpoint/band files or `qids_common_only` for the EN-ZH convenience subset file.
`band_label`	Ratio label such as `0`, `20-40`, or `100`.
`band_low`	Lower target-share boundary for the file.
`band_high`	Upper target-share boundary for the file.
`band_mid`	Midpoint of the ratio band.
`qid`	Query identifier.
`text`	Query text.
`is_common_qid`	Whether the qid appears in the pair's `qids-common.tsv`.
