Comparing learnability of two dependency schemes: ‘semantic’ (UD) and ‘syntactic’ (SUD) (2021.findings-emnlp)

| Challenge: | Several studies have suggested that choosing syntactic criteria for assigning heads in dependency trees improves the performance of dependency parsers. |
| Approach: | They propose to use syntactic criteria to assign heads to dependency trees to improve the performance of dependency parsers by using a selection of 21 treebanks. |
| Outcome: | The proposed approach favours content words over function words as heads of dependency relations, while the other favours syntactic heads. |

| Challenge: | Existing work on how to integrate world knowledge into a QSD model has been limited . |
| Approach: | They use a scope-disambiguated corpus annotated with prepositional senses to integrate our knowledge into a machine learning model. |
| Outcome: | The proposed model is based on a scope-disambiguated corpus annotated with prepositional senses . Statistical analysis shows that prepositions have a positive impact on the learnability of automatic QSD systems. |
