| Challenge: | Using the examples of English and German, we examine how parsers trained on modern variants of these languages can be transferred to older language levels without loss. |
| Approach: | They develop a treebank of diachronic corpora enriched with dependency annotations using 3 parsers, 6 pre-trained language models, 5 newly trained models for German, and two tag sets. |
| Outcome: | The proposed treebank covers the time period from 1800 until today and is based on the DependencyAnnotator annotation tool. |
