6-31 (2017-06-19) PhD position in Computational Linguistics for Ambient Intelligence, Grenoble, France
  

Keywords: Natural language understanding, decision support system, smart home

The Laboratoire d'Informatique de Grenoble (LIG) of the University Grenoble Alpes, Grenoble, France invites applications for a PhD position in Computational Linguistics for Ambient Intelligence.

University of Grenoble Alpes is situated in a high-tech city located at the heart of the Alps, in outstanding scientific and natural surroundings. It is 3h by train from Paris ; 2h from Geneva and is less than 1h from Lyon international airport.

The position starts in September 2017 and ends in July 2020 and is proposed in the context of the national project Vocadom (http://vocadom.imag.fr/) whose aim is to build technologies that make natural hand-free speech interaction with a home automation system possible from anywhere in the home even in adverse conditions [Vacher2015].

The aim of the PhD will be to build a new generation of situated spoken human machine interaction where uttered sentences by a human are understood within the context of the interaction in the home. The targeted application is a distant speech hand free and ubiquitous voice user interface to make the home automation system react to voice commands [Chahuara2017]. The system should be able to process possibly erroneous outputs from an ASR system (Automatic Speech Recognition) to extract meaning related to a voice command and to decide about which command to execute or to send a relevant feed-back to the user. The challenge will be to constantly adapt the system to new lexical phrases (no a priori grammar), new situations (e.g., unseen user, context) and change in the house (e.g., new device, device out of order). In this work, we propose to extend classical S/NLU (Natural Language Understanding) approaches by including non-linguistic contextual information in the NLU process to tackle the ambiguity and borrow zero-shot learning techniques [Ferreira2015] to extend the lexical space on-line. Reinforcement learning is targeted to adapt the models to the user(s) all along the use of the system [Mnih2015].
The candidate will be strongly encouraged to publish their progress to the main events of the field (ACL, Interspeech, Ubicomp).
The PhD candidate will also be involved in experiments including real smart-home and real users (elderly people and people with visual impairment) [Vacher2015].
