UniMorph + UniSegments Morph Data

This dataset pairs UniMorph inflectional features with UniSegments segmentations. For languages without UniSegments coverage, segmentation defaults to the unsegmented word form itself.

This resource is a necessary component for evaluating Tokenizer Morphological Plausibility, as introduced in Tokenizer Morphological Plausibility (https://arxiv.org/abs/2601.18536). The data generation process follows the implementation provided in the official repository of the paper: https://github.com/abishekjs/morph-tok-eval/blob/main/data.py

⚠️ Some language files are very large, so morphological plausibility evaluation can take a long time. This is an intrinsic limitation of the metric because it involves training IBM Models. You can reduce runtime by using fewer iterations or by down‑sampling the data (we don’t have a recommended down‑sampling strategy).

Sources

Data Generation Logic

For each language lang (ISO 639-3), the UniMorph source file is {lang}.segmentations when present, otherwise {lang}. When a UniSegments resource exists for a language, it is preferred from MorphyNet when multiple resources are available. For each UniMorph line, output:

(form, features, segments)

where:

  • form is UniMorph column 2
  • features is UniMorph column 3
  • segments comes from UniSegments column 4 with " + " replaced by | (Not necessary for evaluation)

If a language has no UniSegments file, segments is set to the unsegmented form.

Output is a TSV without headers at {lang}.tsv.

Language Availability

  • Total languages in this repo: 179
  • Languages with UniSegments coverage: 25
  • Languages without UniSegments coverage (segmentation defaults to form): 154

Derived languages: bos, hrv, and snr are direct copies of hbs. srp is a Cyrillic transliteration of hbs.

Languages with missing UniMorph license metadata:

hsb, jpn, kca, ket, kor, slp, wmt

File Format

Each row in {lang}.tsv has 3 columns:

  1. form
  2. features
  3. segments

License

Each language file inherits the more restrictive license between its UniMorph source and UniSegments source (when present). The table below lists the final per-language license and source licenses. If a license is null, it was not found in the source metadata.
