Characterizing Idioms: Conventionality and Contingency (2022.acl-long)
Copied to clipboard
| Challenge: | idioms have non-canonical meanings, but non-conventional meanings are contingent on other words . a recent study shows that idiomatic expressions are not homogeneous among idiomas . |
| Approach: | They propose to use a contingency relationship between words in an idiom and non-canonical meanings of words in the idiome. |
| Outcome: | a new study shows that idioms fall at the expected intersection of the two dimensions, but that the dimensions themselves are not correlated. |
Compositional Generalization in Dependency Parsing (2022.acl-long)
Copied to clipboard
| Challenge: | Compositionality is the ability to combine familiar units like words into novel phrases and sentences. |
| Approach: | They introduce a set of dependency parses for Compositional Freebase Queries (CFQ) they analyze the behaviour of a state-of-the-art dependency parser on the CFQ dataset . |
| Outcome: | The proposed dependency parser performs lower on the most challenging splits with the highest compound divergence. |
Morphological Irregularity Correlates with Frequency (P19-1)
Copied to clipboard
| Challenge: | a new measure of irregularity is proposed for inflectional morphology of languages . the measure is based on the predictability of forms in a language . |
| Approach: | They propose a measure of irregularity based on the predictability of forms in a language. |
| Outcome: | The proposed measure is the first of its breadth and confirms longstanding proposals from the linguistics literature. |
