When we think of Franco-German relations, it is clear that they are not described in the same terms on either side of the Rhine. While the figure of the "couple" dominates the perception of Franco-German cooperation in France, in Germany it is seen in terms of the "tandem". By studying the notions, metaphors and patterns of perception used to think about Franco-German relations, this project aims to identify the similarities and differences in the way the French and Germans view relations between their countries. Ultimately, the aim is to find out whether there is a shared Franco-German imaginary. ► Read more

Recent approaches to embedding learning have focused on results, often at the expense of interpretability and algorithmic complexity. Yet, interpretability is a necessary pre-requisite for the deployment of such technologies when they are used in sensitive domains such as law or medicine. Moreover, ecological imperatives create an urgent need to think about efficient and computationally efficient systems. With DIGING, we propose a new powerful and computationally efficient approach for the construction of interpretable lexical plots based on the theory of complex networks. With this original approach, the goal is to build vectors integrating polysemy natively by plunging words into a space with interpretable dimensions.

In order to make these technologies accessible to the largest number of people, ESPERANTO will address applications with limited resources in the field of rare languages, robotics or education.

Media and society have an intricate relationship. Descriptive, the media are also prescriptive and shape our perception of the world. The GEM project aims to describe the differences in representation and treatment between women and men in the media, based on the automatic analysis of large volumes of data in French contained in the INA and Deezer collections: TV, radio, print media and music collections. ► Read more

Effective modeling of variabilities, exhibited by human’s speech at phoneme, word, and sentence levels, is still an open research problem for SLU systems. Even more, extracting relevant keywords, themes or concept mentions from either a sentence or an entire spoken document is a difficult task even for the most advanced end-to-end systems. AISSPER aims to develop new paradigms that jointly model acoustic and semantic information for the semantic analysis of oral documents. ► Read more

ExTENSoR also aims to bring new insights to what information in speech signals is being used in order to arrive at the scores or decisions produced by the network. ExTENSoR will pursue its objectives within the context of automatic speaker recognition and anti-spoofing, two fields of speech processing research showing burgeoning interest in end-to-end, evolutive learning. ► Read more

The MMA group (Mutuelles du Mans Assurances), the leading player in property and casualty insurance in France, is highly involved in the analysis of customer paths. In a customer relationship strategy, MMA wants to determine the factors of satisfaction, commitment and recommendation. Its marketing department conducts satisfaction surveys to collect numerous textual feedback from customers. The volume collected is such that it is impossible to manually process all of this data. That is why the MMA group has called on LIUM's knowledge to automatically analyze opinion information. ► Read more

The lexical resources of SNCF's technical documentation testify to the richness and specificities of the business vocabulary used within companies such as SNCF. This vocabulary is sometimes uncommon in corpuses, but according to experts, it is of major importance for the characterization of documents. ► Read more

The SNCF group is currently undergoing a digital transformation and is increasingly turning to technologies that could use Natural Language Processing (NLP). Business documentation is currently undergoing a major transformation, with businesses that are digitising themselves, becoming more mobile and with new ways of consuming information. Various internal projects have helped to initiate a transition to digital, to find the right information at the right time. Beyond the digitisation of documents, the question arises of new intelligent systems for access to content, interpretation and data entry. The aim of the project is to identify, design and evaluate solutions that can enrich current digital documentation initiatives. The fields of application are writing assistance, information retrieval and navigation in text content. ► Read more

The goal of the ALLIES project is to encourage and demonstrate the development of autonomous systems, able to sustain performance across time according to a given learning scenario. A learning scenario defines the importance given to the performance on “past” and “present” data in the optimization (or evaluation) process. By setting the learning scenario, a human supervisor (HS) allows or forbids the system to forget. In ALLIES, an autonomous system is fully unsupervised, incrementally adapting its models but also their structure to learn or forget events according to the given learning scenario and data that it automatically collects across time. ► Read more

As of September 2016, computer programming is part of the official program in French middle schools. Many teachers, who do not have any training in computer science, are therefore in need of tools to help them. It is in this context that we designed TurtleTable, a Learning Games that has two main originalities. First of all, unlike most of the existing applications, this game is not based on activities where one has to write a computer program. Instead, the players have to execute a given program, step by step, just like a computer. ► Read more

The urbanization of society has gradually separated men from the plant world. Indeed, most people no longer live in a natural environment and have forgotten the names of plants and trees and the potential uses that can be made of them. Still, generations of botanists have accumulated knowledge about plants and many people are interested in nature and aware that natural resources are a treasure we must preserve. However, it is undeniable that, for a majority of people, botany remains difficult to understand. ► Read more

The EmoTED project aims to explore Virtual Reality technological solutions and techniques in order to help the mimicry of emotions for children with ASD. It involved two academic partners, ENSAM and LIUM, and one association about ASD, Cocci’Bleue. The project was supported by a programme funding organisation from local authorities for a period of 18 months. The project followed a global action-research methodology towards a main objective: to design and develop a facial-recognition prototype for helping children with ASD to learn about the mimicry of emotions. ► Read more

Communication is one of the necessary condition to develop intelligence in living beings. Humans use several modalities to exchange information: speech, written text, both in many languages, gestures, images, and many more. There is evidence that human learning is more effective when several modalities are used. There is a large body of research to make computers process these modalities, and ultimately, understand human language. These modalities have been, however, generally addressed independently or at most in pairs. However, merging information from multiple modalities is best done at the highest levels of abstraction, which deep learning models are trained to capture. ► Read more

This project will build and develop JOKER, a generic intelligent user interface providing a multimodal dialogue system with social communication skills including humor, empathy, compassion, charm, and other informal socially-oriented behavior. ► Read more

The objective of the Hubble project is to create a national observatory for the building and sharing of massive data analysis processes, from traces left in e-learning environments. Hubble will enable to analyze and explain phenomena of teaching and learning with these environments. ► Read more

In a context marked by the necessity of developing the attractiveness of training courses, receiving new types of learners and designing learning systems that help to develop skills rather than strictly disciplinary knowledge, digital epistemic games come up as an alternative pedagogy to traditional approaches. Epistemic games are playful and authentic learning situations that lead the learner to solve complex and non-determinist issues. These games are based on simulation, augmented reality and tangible interfaces in order to design authentic learning situations in terms of interactions enabled. They aim at developing the learner’s capacity to mobilize a number of various resources (knowledge and skill sets) in a given context and his/her ability to reflect on this approach as well as on the learner’s capacity to reorganize of these resources. Thus, from a pedagogical point of view, epistemic games rely on a skills-based approach. ► Read more

The VERA project aims at developing tools for diagnostic, localization, and measurements of automatic transcription errors. This project is based on a consortium of first-rate academic actors in this field. The objective is to study the errors in detail (at the perceptive, acoustico-phonetics, lexical, and syntactic levels) in order to yield a precise diagnosis of possible lacks of the current classical models on certain classes of linguistic phenomena.

Les ULIS (unités localisées pour l’inclusion scolaire) accueillent des élèves présentant des troubles cognitifs ou mentaux. L’objectif principal de la scolarisation dans la classe ULIS est le développement d’une autonomie adulte et d’une insertion socioprofessionnelle durable dans la société. ► Read more

Nowadays, LMSs are widely spread in academic institutions and not restricted to distant courses but are also useful during or in complement to face-to-face learning sessions. Design skills can be acquired through specific teacher education programs, often focusing on the features and technical aspects of the platform. Few courses deal with how to design pedagogically sound learning situations. Teachers develop ad hoc and individual learning design techniques by diverting and experiencing combination of LMSs’ features and functionalities. In such context, it is relevant to help teachers in focusing on pedagogical aspects and their instructional design setting-up for the specific LMS they have at their disposal. ► Read more
