TL;DR

This paper explores idiomatic expression detection using large language models in zero and one-shot learning settings, achieving promising F1 scores on English and Portuguese datasets.

Contribution

It introduces a novel approach applying zero and one-shot learning with large language models to idiomaticity detection across multiple languages.

Findings

F1 score of 0.73 in zero shot setting

F1 score of 0.85 in one shot setting

Effective cross-lingual idiomaticity detection

Abstract

Large Language Models have been successful in a wide variety of Natural Language Processing tasks by capturing the compositionality of the text representations. In spite of their great success, these vector representations fail to capture meaning of idiomatic multi-word expressions (MWEs). In this paper, we focus on the detection of idiomatic expressions by using binary classification. We use a dataset consisting of the literal and idiomatic usage of MWEs in English and Portuguese. Thereafter, we perform the classification in two different settings: zero shot and one shot, to determine if a given sentence contains an idiom or not. N shot classification for this task is defined by N number of common idioms between the training and testing sets. In this paper, we train multiple Large Language Models in both the settings and achieve an F1 score (macro) of 0.73 for the zero shot setting and an F1 score (macro) of 0.85 for the one shot setting.
