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

The Universal Dependencies treebank for Swedish Sign Language (ISO 639-3: swl) is derived from the Swedish Sign Language Corpus (SSLC) from the department of linguistics, Stockholm University.


Selected portions of SSLC have been manually annotated according to our adapted version of the Universal Dependencies guidelines.


Syntactic annotation is mainly due to Moa Gärdenfors with assistance from Carl Börstell and Mats Wiren. Carl Börstell, Robert Östling and Lars Wallin have contributed to the part-of-speech annotations. Robert Östling has contributed software for converting between the annotation format (ELAN) and CoNLL-U.
