New Semantic Task for the French Spoken Language Understanding MEDIA Benchmark
Abstract
Intent classification and slot-filling are essential tasks of Spoken Language Understanding (SLU). In most SLU
systems, those tasks are realized by independent modules. For about fifteen years, models achieving both of them
jointly and exploiting their mutual enhancement have been proposed. A multilingual module using a joint model
was envisioned to create a touristic dialogue system for a European project, HumanE-AI-Net. A combination of
multiple datasets, including the MEDIA dataset, was suggested for training this joint model. The MEDIA SLU dataset
is a French dataset distributed since 2005 by ELRA, mainly used by the French research community and free for
academic research since 2020. Unfortunately, it is annotated only in slots but not intents. An enhanced version of
MEDIA annotated with intents has been built to extend its use to more tasks and use cases. This paper presents the
semi-automatic methodology used to obtain this enhanced version. In addition, we present the first results of SLU
experiments on this enhanced dataset using joint models for intent classification and slot-filling.
