TurkuNLP/webmeta-demo-fi-sv

webmeta demo sample (HPLT 4, Finnish and Swedish)

A small random sample of HPLT 4 web documents: 2,000 in Finnish and 2,000 in Swedish. It is the demo data for webmeta, a tool that turns a large web corpus into research datasets by settings. Its Colab notebook reads this dataset.

The sample is small on purpose, so that the notebook runs in a few seconds. For research use, draw from the full corpus.

What was sampled

• Corpus: HPLT 4.0, clean subset, fin_Latn and swe_Latn.

• Quality levels 8–10 only. HPLT 4 assigns each document a web document quality score (WDS); the level is the first decimal of that score, as in HPLT's shard names.

• A simple random sample within each language, drawn over all documents at those levels. Levels are therefore represented in proportion to their size:

  Level	Finnish	Swedish
  8	1,533	1,687
  9	457	309
  10	10	4

• Drawn on 2026-10-28 with TurkuNLP's HPLT sampler, seed 20261028; every count was checked against the sampling plan and the corpus files.

Fields

Every record is an HPLT 4 document with all of its fields as released, e.g. id, u (URL), text, doc_scores, language identification (openlid_v3, seg_langs_openlid_v3, glotlid_v3) and register probabilities (web-register). See HPLT 4 for the field definitions. The two languages share one schema: a field that HPLT gives for only some documents is empty (null) elsewhere.

webmeta reads these fields to add language, register and country metadata; it does not change them.

Use

from datasets import load_dataset
ds = load_dataset("TurkuNLP/webmeta-demo-fi-sv", split="train")         # both languages
fi = load_dataset("TurkuNLP/webmeta-demo-fi-sv", "fin", split="train")  # Finnish only

With webmeta:

import webmeta
docs = webmeta.run(webmeta.read("TurkuNLP/webmeta-demo-fi-sv"), adapter="hplt4", country="FI")
