Interpreting Character Embeddings With Perceptual Representations: The Case of Shape, Sound, and Color (2022.acl-long)
Copied to clipboard
| Challenge: | Character-level information is included in many NLP models, but evaluating the information encoded in character embeddings is an open issue. |
| Approach: | They propose to use shape, sound, and color embeddings to evaluate the information encoded in character representations in five languages to perform cross-lingual analysis. |
| Outcome: | The proposed classifiers evaluate phonological information encoded in character embeddings and LSTM models. |
Letters From the Past: Modeling Historical Sound Change Through Diachronic Character Embeddings (2022.acl-long)
Copied to clipboard
| Challenge: | a great deal of work has been done on NLP approaches to lexical semantic change detection, but other aspects of language change have received less attention from the NLP community. |
| Approach: | They propose to compare the relative distance through time between the distributions of the characters involved before and after a sound change has taken place. |
| Outcome: | The proposed method can trace the well-known historical change of lenition of plosives in Danish historical sources and identify several of the changes under consideration and uncover meaningful contexts in which they appeared. |
