Cross-lingual question retrieval benchmark built from Multilingual Knowledge Questions & Answers across 26 languages. Current leaders and methodology for MKQA.

Overview

Cross-lingual question retrieval benchmark built from Multilingual Knowledge Questions & Answers across 26 languages.

How it is measured: Aggregate Recall@100 for multilingual query-to-English-passage retrieval; model records must preserve the reported dense, sparse, or hybrid configuration.

What this benchmark measures

  • multilingual open-domain question answering
  • cross-lingual answer consistency

Relevant to:

  • multilingual assistant screening
  • language-coverage planning

Failure modes it exercises:

  • answer-quality collapse in low-resource languages

Method and its limits

10k question-answer pairs aligned across 26 languages, for 260k pairs in total, with answers curated in a language-independent representation rather than tied to language-specific passages.

  • Answers are deliberately retrieval-independent, so the benchmark does not test grounding against a corpus.
  • The paper reports the set is challenging even in English and markedly harder in low-resource languages, so cross-language comparisons reflect dataset difficulty as well as model ability.

How to read this score

Scores are comparable across languages by design, which is the benchmark's main contribution; absolute values depend on the answer-matching rule used.

Similarity to real tasks: Medium — Established from the primary methodology: MKQA aligns 10k question-answer pairs across 26 typologically diverse languages, with answers held in a language-independent representation so results are comparable across languages. Open-domain question answering resembles assistant workloads. It does not reproduce a deployed system, because retrieval, grounding, and refusal behaviour are outside the benchmark.

Data contamination risk: High — MKQA derives from Natural Questions and has been public since 2020, so overlap with training corpora is likely. No run-specific audit is registered.

Benchmark gaming risk: Low — There is no prominent public leaderboard creating direct optimisation pressure, though answer-matching rules still affect reported numbers.

What you still need to test yourself

  • Add retrieval and grounding, which this benchmark deliberately excludes.
  • Re-check answers whose correctness may have changed since 2020.

This benchmark supports decisions about:

  • Compare answer quality across languages on a like-for-like question set.
  • Identify languages where a candidate model degrades.

Limitations

  • Not evidence of grounded or retrieval-augmented answer quality.
  • Time-sensitive answers may now be outdated.

Primary source reviewed 2026-10-11. MKQA is treated as an aging 2020 benchmark whose answers encode 2020 world knowledge.

What this evidence does not cover

  • Only one model is currently scored on this page, so no cross-model comparison is supported.

It establishes the dataset's size and language coverage; it does not establish retrieval-corpus currency or any model's score.
