IWPT 2021 Shared Task Results of combo/primary

Coarse F₁ Scores

Each score pertains to the combined test set of the language, without distinguishing individual treebanks and the enhancement types they annotate. The last line shows the macro-average over languages.

Qualitative F₁ Scores

The system output for each language was split into parts corresponding to individual source treebanks. The scores then ignore errors in enhancement types for which the treebank lacks gold-standard annotation. The column LAvgELAS shows the qualitative ELAS averaged over treebanks of the same language; the final average in bold is averaged over languages rather than treebanks. For comparison, the last column then shows the coarse ELAS F₁ for the given language.
