Information about the model

Note: the model is currently being fine-tuned in the context of my PhD. I'll fill this part when it will be done.

The training set is roughly 1.5M tokens, dev test roughly 10k and test 169822. This is not counting punctuation, as LASLA data are lacking punctuation.

  • Enclitics are kept in a single token
    • Enclitic lemma are separated as such token[Caesarque] == lemma[Caesar界que]
    • Morphology is the morphology of the first token
  • Only numbers 1, 2 and 3 are known. Roman numbers are unknown.
  • All punctuation signs are unknown, including the one used in abbr. token[C] == lemma[Gaius]
  • Lemma and tokens now accept lower and uppercasing. Noise was introduced in the dataset for better results.

Model LASLA Plus

The model LASLA+ is trained on additionnal data, creating some noise in the original dataset and resulting in apparently worse results on classical data (approxim. -0.3%). It's results are detailed in LASLA-plus.md.
