A Collection of Question Answering Datasets for Norwegian
T0 review · 3 major / 5 minor · reviewed 2026-08-10 · deepseek-v4-flash
Pith's one-line read A new suite of four Norwegian QA datasets, built by native speakers, covers both Bokmål and Nynorsk and reveals that language models perform worse in Nynorsk, struggle with commonsense reasoning, and often repeat falsehoods.
desk verdict A solid, genuinely useful Norwegian QA resource that fills a real gap, but the empirical model-ranking claims should be read with the paper's own caveats about localization and annotation quality in mind. read the letter →
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The central object is the collection itself, built by a two-stage annotation process: first, native-speaker annotators manually translated, localized, and creatively rewrote items from OpenBookQA, CommonSenseQA, and TruthfulQA; second, a curation stage filtered low-quality examples and checked spelling and grammar. NRK-Quiz-QA was assembled from more than 500 quizzes from the Norwegian public broadcaster, with temporal references adjusted and image-dependent items removed. The evaluation uses multiple-choice scoring by token probability for three datasets and free-form generation scored by ROUGE-L for the generation subset, across a pool of prompts per language standard.
What would settle it
Have a group of bilingual Norwegian–English speakers answer a random sample of the original English OpenBookQA and CommonSenseQA items and the corresponding Norwegian versions, and compare human accuracy and item difficulty; if accuracy or difficulty diverge sharply, the Norwegian datasets are not measuring the same constructs. Also, double-annotate a sample of the curated items to measure inter-annotator agreement on quality; low agreement would weaken the curation claim.
Extended reading notes
Core claim
On the paper's own terms: Norwegian QA resources have been limited to extractive or translated reading-comprehension datasets in Bokmål; this collection is the first to cover both official written standards and to target commonsense reasoning, truthfulness, and Norwegian-specific knowledge, with items written by native speakers rather than machine-translated. The reported evaluations show consistent performance gaps that suggest these abilities are not yet well supported in Norwegian language models.
Load-bearing premise
The pipeline that translates, localizes, and creatively rewrites English items into Norwegian preserves the abilities the original datasets measure, and the single-annotator curation of 80% of examples is sufficient to ensure item quality.
Editorial extensions
If this is right
- Norwegian language models can now be benchmarked on commonsense and truthfulness separately from reading comprehension, in both Bokmål and Nynorsk.
- The consistent Bokmål-over-Nynorsk gap identifies minority-language coverage as a specific weakness to target in pretraining and evaluation.
- The low truthfulness scores indicate that Norwegian models reproduce human misconceptions, so mitigation efforts need Norwegian-specific data.
- The few-shot results on NorOpenBookQA suggest that adding demonstrations is not monotonic; 4-shot often beats 16-shot, informing practical evaluation protocols.
- The public release under a permissive license lets other researchers reuse the datasets for training and cross-lingual comparison.
Reading between the lines
- Because localization can change question difficulty, the claim that models struggle with commonsense reasoning could be an artifact of changed item difficulty; a bilingual human-answer study comparing item-level difficulty against the English originals would test this directly.
- The Nynorsk subsets are small (e.g., 95 examples for NorCommonSenseQA and 57 for NorTruthfulQA multiple-choice), so NN score differences should be read with wide error bars; expanding NN coverage is a natural next step.
- The NRK quiz items are zeitgeist-dependent and may leak into pretraining corpora; a contamination check on those items would harden the benchmark.
- The NorOpenBookQA training split enables future instruction tuning or continued pretraining on Norwegian world-knowledge data, which the authors do not explore.

A structured set of objections, weighed in public.
Referee Report
Summary. This paper presents four new Norwegian QA datasets: NorOpenBookQA, NorCommonSenseQA, NorTruthfulQA (multiple-choice and generation), and NRK-Quiz-QA, covering both Bokmål and Nynorsk. The datasets are created by native-speaker annotators through manual translation and localization of OpenBookQA, CommonSenseQA, and TruthfulQA, together with newly written examples and adapted material from NRK quizzes. The authors describe the annotation pipeline, report dataset statistics, and evaluate 11 language models in zero- and few-shot regimes. The main empirical findings are that most models score higher in Bokmål than Nynorsk, that commonsense reasoning is the weakest skill, and that models often reproduce human falsehoods. All datasets and annotation materials are publicly released.
Significance. If the resource is valid, it makes a substantial contribution: it is the first Norwegian QA collection covering both written standards, with multiple task formats and Norwegian-specific content, and it provides a reusable evaluation harness. The paper is commendably transparent about its limitations, including the 80% curation rate, lack of inter-annotator agreement, and absence of human baselines. The public release under a permissive license and the integration with NorEval are concrete strengths that will benefit the community. However, the strength of the empirical conclusions is currently limited by validation gaps; the resource itself is valuable, but the evidence that the adapted datasets measure the intended constructs is incomplete.
major comments (3)
- [§3.1.1, §3.6, §7] The paper's central empirical claims—that LMs struggle most with commonsense reasoning and are often untruthful in Norwegian—presuppose that NorCommonSenseQA and NorTruthfulQA measure the same constructs as their English source datasets. Section 3.1.1 explicitly permits annotators to localize and creatively adapt items, and Section 3.6 reports that the Norwegian questions are 'somewhat shorter' and 'less complex' than the English originals (e.g., 'Hvor kommer kumelk fra?'). This is internal evidence that adaptation can lower the cognitive demand of individual items. Because Section 7 states that only 80% of examples were curated, each by a single annotator, with no inter-annotator agreement, and no human baseline was collected, there is currently no quantitative check on construct validity. I ask the authors to add (i) a human baseline on a random sample, (ii) an item-level difficulty comparison with the English originals (e.g., correlation of per-item model accuracy), and (iii) a report of how many items were translated, localized, or newly created, with an analysis of whether localization changes answer distributions.
- [Table 2, §5] The Nynorsk subsets are very small: NorOpenBookQA has 253 NN examples, NorCommonSenseQA has 95, and NorTruthfulQA Multiple-choice has 57. Claims such as 'most LMs perform better in NB than NN' and the NN-specific observations in Section 5 (e.g., only three models surpass 40% on NorCommonSenseQA NN) rest on samples where a difference of 5–8 percentage points is within binomial noise. The authors should report confidence intervals or significance tests for the NB–NN comparisons, and should soften or qualify the corresponding conclusions, particularly for datasets with fewer than roughly 100 NN examples.
- [§4 Result Aggregation] The evaluation protocol reports the maximum accuracy and ROUGE-L across the pool of 50 prompts for each model. Maximum-of-prompts is an optimistic summary and can make model rankings sensitive to a single prompt; it is also not accompanied by any variance estimate. Since the paper's empirical conclusions are based on these numbers, I request that the authors also report mean and standard deviation (or per-prompt distributions), and that they fix and document the random seed used for k-shot demonstration sampling.
minor comments (5)
- [Throughout] The dataset name is spelled inconsistently as 'NorCommonsenseQA' and 'NorCommonSenseQA'; please unify to a single spelling.
- [§3.1] The name 'NortruthfulQA' appears with a lowercase 't' at the start of Section 3.1; use 'NorTruthfulQA' consistently throughout.
- [§3.6] The manual comparison of 100 examples should state which datasets and annotators were involved and how the sample was drawn, so readers can interpret the claim about question length and complexity.
- [§4] The k-shot demonstration examples are sampled randomly without a stated seed; this makes the few-shot results non-reproducible as reported.
- [Table 4] The column header for NorOpenBookQA appears to duplicate 'NB'; check that the two k-shot blocks are labeled unambiguously.
Circularity Check
No circularity: the dataset creation and model evaluation are independent of any fitted target or self-referential evidence.
full rationale
This is a resource paper, not a derivation. The claimed contributions are four new Norwegian QA datasets created by native-speaker translation, localization, and original writing, followed by an empirical evaluation of publicly available language models. There is no mathematical derivation or fitted parameter that is later presented as a prediction. The benchmark accuracy and ROUGE-L scores in Table 4 are computed on held-out test sets with no tuning to any desired outcome, so no result reduces by construction to its inputs. The only self-references are citations to the authors' own prior models (e.g., Samuel et al., 2025, for NORA.LLM) and to their NorEval evaluation toolkit; these are used as evaluation subjects and tooling, not as evidence that the datasets measure the intended abilities. The paper explicitly discloses the absence of human baselines and inter-annotator agreement, and these are acknowledged validity limitations rather than circular reasoning. No quoted step in the paper exhibits the formal pattern of an output being equivalent to its input, whether through definition, fitting, or a self-citation chain. The central claim that the datasets cover world knowledge, commonsense, truthfulness, and Norwegian-specific knowledge rests on the annotation design and is independently assessable against the released data and external benchmarks.
Assumptions & free parameters
assumptions (5)
- domain assumption Manual translation and localization preserves the validity and difficulty of the original English QA tasks.
- domain assumption Single-annotator validation on 80% of examples is sufficient to guarantee dataset quality.
- domain assumption NRK quiz data from 2017 to 2024 is high quality and suitable for benchmarking after temporal adjustment.
- domain assumption Maximum accuracy across 50 prompts is a valid performance measure.
- domain assumption ROUGE-L against reference answers is a valid measure of truthfulness.

This paper introduces a new suite of question answering datasets for Norwegian; NorOpenBookQA, NorCommonSenseQA, NorTruthfulQA, and NRK-Quiz-QA. The data covers a wide range of skills and knowledge domains, including world knowledge, commonsense reasoning, truthfulness, and knowledge about Norway. Covering both of the written standards of Norwegian - Bokm{\aa}l and Nynorsk - our datasets comprise over 10k question-answer pairs, created by native speakers. We detail our dataset creation approach and present the results of evaluating 11 language models (LMs) in zero- and few-shot regimes. Most LMs perform better in Bokm{\aa}l than Nynorsk, struggle most with commonsense reasoning, and are often untruthful in generating answers to questions. All our datasets and annotation materials are publicly available.
