Challenge: Existing data on metaphor novelty are limited, making it difficult to perform research on this topic.
Approach: They propose to release a corpus of metaphor novelty scores for syntactically related word pairs . they establish a performance benchmark to which future researchers can compare .
Outcome: The proposed corpus of metaphor novelty scores is compared to other datasets . it performs better than chance or nave strategies, the authors show .

Weeding out Conventionalized Metaphors: A Corpus of Novel Metaphor Annotations (D18-1)

Copied to clipboard

Challenge: a lack of datasets distinguish between conventionalized and novel metaphors is limiting research . a novel metaphor is often overlooked or intentionally disregarded, authors say .
Approach: They propose a crowdsourced annotation layer for an existing metaphor corpus to investigate novelty . they investigate correlations between concreteness ratings and more semantic features .
Outcome: The proposed method combines novel metaphor annotations with concreteness ratings and semantic features.

An analysis of language models for metaphor recognition (2020.coling-main)

Copied to clipboard

Challenge: Metaphor recognition systems that are based on language models perform substantially worse on unconventional metaphors than on conventional ones.
Approach: They conduct a linguistic analysis of recent metaphor recognition systems based on language models and a variant of BERT language models to examine their performance.
Outcome: The proposed systems show that they can recognise unseen words if synonyms or morphological variations have been seen before, leading to enhanced generalisation beyond word sense disambiguation.

Challenge: Novel metaphor comprehension involves complex semantic processes and linguistic creativity.
Approach: They propose a cloze-style surprisal method that conditions on full-sentence context.
Outcome: The proposed method shows that LM surprisal yields moderate correlations with scores/labels of metaphor novelty.
Improving Neural Metaphor Detection with Visual Datasets (2020.lrec-1)

Copied to clipboard

Challenge: a new method for metaphor detection uses text from visual datasets to identify words . a metaphor is a complex interaction between two terms, creating an "implicationcomplex"
Approach: They propose a technique for sampling text from visual datasets to create a visibility word embedding.
Outcome: The proposed method improves on previous approaches that use more complex neural networks and richer linguistic features for verb classification.
Verifying Claims About Metaphors with Large-Scale Automatic Metaphor Identification (2024.naacl-short)

Copied to clipboard

Challenge: Existing studies on metaphors have focused on a small number of examples, whereas few studies verify claims with large corpus.
Approach: They propose to use a large corpus to verify existing claims about verb metaphors . they apply metaphor detection to sentences extracted from Common Crawl .
Outcome: The proposed method identifies verb metaphors with lower concreteness, imageability, familiarity and more emotional and subjective sentences.
Metaphors in Online Religious Communication: A Detailed Dataset and Cross-Genre Metaphor Detection (2024.lrec-main)

Copied to clipboard

Challenge: figurative language plays a particularly important role in religious communication . linguistic metaphors relate entities from different semantic domains by drawing on an implicit similarity between them.
Approach: They present a dataset of fine-grained metaphor annotations for online religious communication . they show that cross-genre transfer metaphor detection leads to a drop in performance .
Outcome: The proposed dataset shows that adding in-genre data improves performance . the authors show that the proposed system can detect metaphors in religious forums .
Neural Metaphor Detection in Context (D18-1)

Challenge: Existing models focus on limited forms of linguistic context, such as unigrams.
Approach: They propose end-to-end neural models for detecting metaphorical word use in context . they show that bi-directional biLSTM models which operate on complete sentences work well .
Outcome: The proposed models show that they can learn rich contextual word representations . they are compared to previous models which focused on limited linguistic context .

Copied to clipboard

Challenge: Existing methods for metaphor interpretation are slow due to lack of annotated datasets and effective pre-trained language models.
Approach: They propose a large annotated dataset and a PLM for the metaphor interpretation task.
Outcome: The proposed method improves on metaphor identification and interpretation with comparable baselines on the new dataset.
