Understanding Feature Focus in Multitask Settings for Lexico-semantic Relation Identification (2021.findings-acl)
Copied to clipboard
| Challenge: | Lexico-semantic relations embody symmetric and asymmetric linguistic phenomena such as synonymy (e.g. phone telephone), cohyponymy (, cohypoonymy, hypernymy, meronymy) and more can be enumerated. |
| Approach: | They propose to combine feature engineering and multitask architectures to identify lexico-semantic relations by combining asymmetric distributional features with shared-private models. |
| Outcome: | The proposed models improve over binary and fully-shared classifiers and balance the focus on features between private and shared layers 1 and 2 . |
