You can report bugs in this treebank in the treebank-specific issue tracker on Github. If you want to collaborate, please contact [lauma (æt) ailab • lv].

UD_Latgalian-Cairo is an example treebank to provide minimal dataset for Latgalian based on the Cairo sample sentences. Created by AI Lab at Institute of Mathematics and Computer Science, University of Latvia.

This treebank was developed as a proof-of-concept by the team developing Latvian UD Treebank (UD_Latvian-LVTB). It contains the 20 Cairo example sentences and is as far as we are know the only Latgalian treebank in existance.


This work was supported by the State Research Programme’s project Research on Modern Latvian Language and Development of Language Technology under the grant agreement No. VPP-LETONIKA-2021/1-0006.
