Investigating Dictionary Expansion for Video-based Sign Language Dictionaries (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Currently, most dictionary retrieval methods only work with fixed vocabularies, and it is unclear how they might support dictionary expansion without retraining. |
| Approach: | They propose to use a representation-based method to explore the feasibility of dictionary expansion for sign language dictionaries. |
| Outcome: | The proposed method improves sign language dictionaries by varying number of signs added and amount of data for newly added signs. |
