ChainNet: Structured Metaphor and Metonymy in WordNet (2024.lrec-main)
Copied to clipboard
| Challenge: | In a typical lexicon, word senses are encoded as a list, without inter-sense relations. |
| Approach: | They propose a lexical resource which explicitly identifies the senses of a word's senses by expressing how they are derived from one another. |
| Outcome: | The proposed resource expresses how senses in the Open English Wordnet are derived from one another. |
A Tale of a Probe and a Parser (2020.acl-main)
Copied to clipboard
| Challenge: | researchers train supervised models to extract linguistic structure from output of another model . supervised model can be used to perform tasks such as part-of-speech tags or dependency trees . |
| Approach: | They compare a structural probe to a more traditional parser with a lightweight parameterisation. |
| Outcome: | The structural probe outperforms a traditional parser on seven of nine languages . the researchers found that the model outperformed the parsers by 11.1 points . |
Do Syntactic Probes Probe Syntax? Experiments with Jabberwocky Probing (2021.naacl-main)
Copied to clipboard
| Challenge: | a study of neural language models shows that syntactic probes do not properly isolate syntax. |
| Approach: | They show that syntactic probes do not properly isolate syntax . they train two probes trained on normal data and find they perform worse . |
| Outcome: | The proposed method outperforms the baseline models on the most popular models, but their lead is reduced by 53%. |
It’s All in the Name: Mitigating Gender Bias with Name-Based Counterfactual Data Substitution (D19-1)
Copied to clipboard
| Challenge: | Existing attempts to mitigate gender bias rely on operationalisation of gender bias as a projection over a linear subspace. |
| Approach: | They propose to operationalise gender bias as a linear subspace and augmented a corpus to remove bias by swapping all inherently-gendered words in the copy. |
| Outcome: | The proposed approach outperforms projection-based methods at the task of drawing non-biased gender analogies by an average of 19% across both corpora. |
Information-Theoretic Probing for Linguistic Structure (2020.acl-main)
Copied to clipboard
| Challenge: | Neural networks are the backbone of modern stateof-the-art natural language processing systems. |
| Approach: | They propose an information-theoretic operationalization of probing as estimating mutual information that contradicts received wisdom . they evaluate on a set of ten typologically diverse languages often underrepresented in NLP research—plus English—totalling eleven languages. |
| Outcome: | The proposed model outperforms existing models on ten typologically diverse languages and English on 11 languages. |

| Challenge: | The Universal Morphology project provides broad-coverage instantiated morphological inflection tables for hundreds of diverse languages. |
| Approach: | They propose a language-independent feature schema for rich morphological annotation and a type-level resource of annotated data in diverse languages realizing that schema. |
| Outcome: | The proposed schema has added 66 new languages, including 24 endangered languages. |
Metaphorical Polysemy Detection: Conventional Metaphor Meets Word Sense Disambiguation (2022.coling-1)
Copied to clipboard
| Challenge: | Linguists distinguish between novel and conventional metaphors, a distinction which the metaphor detection task in NLP does not take into account. |
| Approach: | They propose a method which treats conventional metaphors as a property of word senses in a lexicon and combines metaphor detection with word sense disambiguation to train it. |
| Outcome: | The proposed model outperforms a state-of-the-art model in annotating metaphor in two subsets of WordNet and achieves .78 ROC-AUC score compared to baseline model . |
Speakers Fill Lexical Semantic Gaps with Context (2020.emnlp-main)
Copied to clipboard
| Challenge: | Lexical ambiguity is widespread in language, allowing for the reuse of economical word forms and thus making language more efficient. |
| Approach: | They propose two ways to estimate lexical ambiguity as the entropy of meanings a word can take . they validate this hypothesis by using WordNet and BERT . |
| Outcome: | The proposed method shows that on six high-resource languages, there are significant correlations between the estimate and the number of synonyms a word has in WordNet. |
