Coordinate Constructions in English Enhanced Universal Dependencies: Analysis and Computational Modeling (2021.eacl-main)
Copied to clipboard
| Challenge: | Enhanced Universal Dependencies (UD) parses are used to represent syntactic dependencies between words, prioritizing links between content words. |
| Approach: | They propose to use a heuristic rule-based converter to propagate conjuncts from conjunction heads to other conjunctions to determine which set of links to propagation from a semantic perspective. |
| Outcome: | The proposed method outperforms existing methods using basic-layer tree parsers and converters. |
VOLIMET: A Parallel Corpus of Literal and Metaphorical Verb-Object Pairs for English–German and English–French (2024.starsem-1)
Copied to clipboard
| Challenge: | Metaphorical language is a complex interplay of cultural and linguistic elements that characterizes metaphorical language . a corpus of parallel sentences containing gold standard alignments of metaphorical verb-object pairs and literal paraphrases is presented . |
| Approach: | They propose to analyze metaphorical verb-object pairs and literal paraphrases in parallel sentences from English to German and French. |
| Outcome: | The proposed corpus of 2,916 parallel sentences reveals monolingual patterns for metaphorical vs. literal uses in English . cross-lingually, the results show a rich variability in translations as well as different behaviors for the two target languages . |
Features of Perceived Metaphoricity on the Discourse Level: Abstractness and Emotionality (2022.lrec-1)
Copied to clipboard
| Challenge: | a metaphorical discourse is more emotional and abstract than a literal one, according to a new study . a metaphorical discourse may be more abstract than literal, but it is not triggered by its emotionality or metaphoricity. |
| Approach: | They examine which features human annotators perceive as important for metaphoricity . they ask: is a metaphorical expression preceded by a more metaphorical/abstract/emotional context? |
| Outcome: | The proposed dataset shows that metaphorical discourses are more emotional and abstract than literal ones. |
What Drives the Use of Metaphorical Language? Negative Insights from Abstractness, Affect, Discourse Coherence and Contextualized Word Representations (2022.starsem-1)
Copied to clipboard
| Challenge: | Existing models of discourse coherence, abstractness and affect are not sufficient to explain metaphorical vs. literal language choices. |
| Approach: | They build five models that predict the use of a metaphorical vs. literal expression in context . they use established cognitive and linguistic properties to define discourse coherence, abstractness and affect . |
| Outcome: | The proposed models show that they do not explain metaphorical vs. literal language choices . metaphors are "not just nice", but represent a "necessary" element of everyday thought and communication . |
