SemEval-2022 Task 2: Multilingual Idiomaticity Detection and Sentence Embedding
This task addresses the challenge of detecting idiomatic expressions in multiple languages for NLP researchers, but it is incremental as it builds on existing shared task frameworks.
The paper introduced a shared task for multilingual idiomaticity detection and sentence embedding, involving binary classification and semantic similarity subtasks across English, Portuguese, and Galician, with nearly 100 participants making over 800 submissions.
This paper presents the shared task on Multilingual Idiomaticity Detection and Sentence Embedding, which consists of two subtasks: (a) a binary classification task aimed at identifying whether a sentence contains an idiomatic expression, and (b) a task based on semantic text similarity which requires the model to adequately represent potentially idiomatic expressions in context. Each subtask includes different settings regarding the amount of training data. Besides the task description, this paper introduces the datasets in English, Portuguese, and Galician and their annotation procedure, the evaluation metrics, and a summary of the participant systems and their results. The task had close to 100 registered participants organised into twenty five teams making over 650 and 150 submissions in the practice and evaluation phases respectively.
