feat: Add new benchmark BEIR-NL #1909

nikolay-banar · 2025-01-30T17:16:41Z

We recently published BEIR-NL, which is a Dutch translated version of BEIR.

Adding datasets checklist

Reason for dataset addition: BEIR-NL, a new benchmark for retrieval in Dutch.

I have run the following models on the task (adding the results to the pr). These can be run using the mteb -m {model_name} -t {task_name} command.
- sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2
- intfloat/multilingual-e5-small
I have checked that the performance is neither trivial (both models gain close to perfect scores) nor random (both models gain close to random scores).
If the dataset is too big (e.g. >2048 examples), considering using self.stratified_subsampling() under dataset_transform()
I have filled out the metadata object in the dataset file (find documentation on it here).
Run tests locally to make sure nothing is broken using make test.
Run the formatter to format the code using make lint.

You also need to add your benchmark to benchmark file

Great to have BEIR-NL added!

I have noted a few additional pointers - @Samoed shouldn't we have a test fail here since the descriptive statistics are missing?

isn't this "derived" from the english data?

Indeed, the "derived" category would fit better. I will change that.

How were these verified?

We manually checked a small subset of translations. If it does not fit into the "verified" category, I can remove that.

No that is perfectly fine - will you add a comment like so:

Suggested change

sample_creation="machine-translated and verified",

sample_creation="machine-translated and verified", # manually checked a small subset

Added a few additional pointers on metadata

Since nothing has been run on these tasks the leaderboard will appear empty. You might consider submitting scores at least for a relevant set of models. If you don't have the resources for this I will have to figure out how we handle an empty benchmark (it might give a bug or lead to confusion on the leaderboard)

mteb/benchmarks/benchmarks.py

+BEIR_NL = Benchmark(
+    name="BEIR-NL",
+    tasks=get_tasks(
+        tasks=[


great - I can see that many models are trained on the English version of these datasets and since they have not been annotated as trained on these datasets they will appear as zero-shot on BEIR-NL (despite being trained on e.g. FEVER). To avoid this you would need to update the model annotations (searching for "NQ"´, "FEVER"` etc. should allow you to find the relevant cases and update the annotations)

I submitted some results to embeddings-benchmark/results#105 and updated the model annotations.

mteb/tasks/Retrieval/nld/ArguAnaNLRetrieval.py

+        eval_splits=["test"],
+        eval_langs=["nld-Latn"],
+        main_score="ndcg_at_10",
+        date=("2024-10-01", "2024-10-01"),


On a second round through the annotations I see that the dates do not quite match the time of the original data (Is it the time of translation?)

I checked the previous translated dataset and there we annotated the data range of the source data.

Feel free to give your best guess here but simply annotate # best guess

Indeed, these dates were the time of translation.

+        domains=["Written"],


Seems like the domains are only minimally filled out. It seems like at least "Non-fiction" would apply to many of these.

Great work! Looks like all comments have been addressed, just need to resolve the merge conflicts. @nikolay-banar would be great to have this merged into the repo soon!

isaac-chung · 2025-02-03T05:04:28Z

mteb/models/arctic_models.py

        "NQHardNegatives": ["test"],
        "HotPotQA": ["test"],
        "HotPotQAHardNegatives": ["test"],
        "HotPotQA-PL": ["test"],  # translated from hotpotQA (not trained on)
+        "HotpotQA-NL": ["test"],  # translated from hotpotQA (not trained on)


@KennethEnevoldsen if these are "not trained on", should we still keep these? Personally I find these very confusing.

I think translating a dataset and training on it should still lead to a non-zero-shot on the benchmark - these are just to annotate that. We could "link" the tasks and update leaderboard code (but currently that is not how it is done)

Got it, makes sense, thanks. The "not trained on" part was confusing for me. Maybe it could have said something closer to "trained on translation" in the future?

nikolay-banar · 2025-02-03T11:56:28Z

@isaac-chung Some tests are failed, but that doesn't seem to be related to my code.

isaac-chung · 2025-02-03T12:15:09Z

@nikolay-banar thanks! I'm rerunning them now.
@KennethEnevoldsen just wanted to see if you're happy with the updates. I'm happy to merge once CI passes. I think we can handle descriptive stats until v2 is merged.

everything is good on my end - so will merge this in

@KennethEnevoldsen I have noticed a small bug in SCIDOCSNLRetrieval.py with eval_langs (it should be ["nld-Latn"]). Should I open a new issue for that?

Samoed · 2025-02-05T10:35:20Z

You can create PR with fix

EwoutH · 2025-08-01T20:27:56Z

This is awesome work!

In the “Language-specific” section of the sidebar on the leaderboard, there isn’t currently a filter for Dutch. Could one be added?
