New Semantic Task for the French Spoken Language Understanding MEDIA Benchmark

COLING 2024main

Intent classification and slot-filling are essential tasks of Spoken Language Understanding (SLU). In most SLU systems, those tasks are realized by independent modules, but for about fifteen years, models achieving both of them jointly and exploiting their mutual enhancement have been proposed. A mu…

Small Language Models Are Good Too: An Empirical Study of Zero-Shot Classification

COLING 2024main

This study is part of the debate on the efficiency of large versus small language models for text classification by prompting. We assess the performance of small language models in zero-shot text classification, challenging the prevailing dominance of large models. Across 15 datasets, our investigat…

Error Analysis Applied to End-to-End Spoken Language Understanding

ICASSP 2020accepted

This paper presents a qualitative study of errors produced by an end-to-end spoken language understanding (SLU) system (speech signal to concepts) that reaches state of the art performance. Different studies are proposed to better understand the weaknesses of such systems: comparison to a classical…

Neural Networks approaches focused on French Spoken Language Understanding: application to the MEDIA Evaluation Task

COLING 2020main

In this paper, we present a study on a French Spoken Language Understanding (SLU) task: the MEDIA task. Many works and studies have been proposed for many tasks, but most of them are focused on English language and tasks. The exploration of a richer language like French within the framework of a SLU…

What is best for spoken language understanding: small but task-dependant embeddings or huge but out-of-domain embeddings?

ICASSP 2020accepted

Word embeddings are shown to be a great asset for several Natural Language and Speech Processing tasks. While they are already evaluated on various NLP tasks, their evaluation on spoken or natural language understanding (SLU) is less studied. The goal of this study is two-fold: firstly, it focuses o…
