Evaluate On-the-job Learning Dialogue Systems and a Case Study for Natural Language Understanding

no code implementations26 Feb 2021 Mathilde Veron, Sophie Rosset, Olivier Galibert, Guillaume Bernard

On-the-job learning consists in continuously learning while being used in production, in an open environment, meaning that the system has to deal on its own with situations and elements never seen before.

Generating Task-Pertinent sorted Error Lists for Speech Recognition

no code implementations LREC 2016 Olivier Galibert, Mohamed Ameur Ben Jannet, Juliette Kahn, Sophie Rosset

In the context of Automatic Speech Recognition (ASR) used as a first step towards Named Entity Recognition (NER) in speech, error seriousness is usually determined by their frequency, due to the use of the WER as metric to evaluate the ASR output, despite the emergence of more relevant measures in the literature.
