Détection hors contexte des émotions à partir du contenu linguistique d'énoncés oraux : le système EmoLogus

The ANR Emotirob project aims at detecting emotions in an original application context: realizing an emotional companion robot for weakened children. This paper presents a system which aims at characterizing emotions by only considering linguistic content. It is based on the assumption that emotions can be compound: simple lexical words have an intrinsic emotional value, while verbal and adjectival predicates act as a function on the emotional values of their arguments. The paper describes the algorithm of compositional computation of the emotion and the lexical emotional norm used by this algorithm. A quantitative and qualitative analysis of the differences between system outputs and expert annotations is given, which shows satisfactory results, with a good detection of emotional valency in 90.0% of the test utterances

Emologus - A Compositional Model of Emotion Detection based on the Propositionnal Content of Spoken Utterances

International audienceThe ANR EmotiRob project aims at detecting emotions in an original application context: realizing an emotional companion robot for weakened children. This paper presents a system which aims at characterizing emotions by only considering the linguistic content of utterances. It is based on the assumption of compositionality: simple lexical words have an intrinsic emotional value, while verbal and adjectival predicates act as a function on the emotional values of their arguments. The paper describes the semantic component of the system, the algorithm of compositional computation of the emotion value and the lexical emotional norm used by this algorithm. A quantitative and qualitative analysis of the dierences between system outputs and expert annotations is given, which shows satisfactory results, with the right detection of emotional valency in 90% of the test utterances

Quelles pistes pour un vécu positif du doctorat ? Apports de la littérature scientifique actuelle

International audienceUn travail de recherche qui ne progresse pas, une supervision insatisfaisante, des perspectives de carrière incertaines ou encore le sentiment de ne pas appartenir à une communauté scientifique, telles sont les difficultés que rencontrent nombre de thésards pendant leur doctorat. Si ces difficultés font l’objet d’un nombre croissant de publications, peu de travaux se sont attachés à mettre en lumière les déterminants du vécu positif du doctorat. En effet, le vécu d’une thèse peut être extrêmement enrichissant. Dans cette revue de la littérature, notre objectif est d’exploiter les connaissances actuelles permettant d’envisager l’expérience du doctorat comme positive pour en extraire des pistes susceptibles d’améliorer cette expérience. Dans un premier temps, nous exposons les éléments de la littérature qui démontrent que, bien que le doctorat puisse être vécu comme une épreuve difficile, il peut également être vécu comme une expérience très positive. Dans un second temps, nous proposons des pistes d’améliorations de l’expérience du doctorat. Dans l’ensemble, cet article, présente un intérêt pour les doctorants désireux d’approfondir leurs réflexions sur leurs conditions de travail, mais aussi pour tous ceux qui les entourent, tels les directeurs de thèse, les directeurs d’unités de recherche, et les directeurs d’écoles doctorales

Human-nature connectedness and sustainability across lifetimes: a comparative cross-sectional study in France and Colombia

International audienceTo face the environmental crisis, international panels called for a transformative change of human-nature interactions which promotes a sustainable relationship between humans and nature. The extent to which people considered themselves as part of nature -known as Human-nature connectedness -has been shown to be a key societal trait for achieving such a transformative change. Human-nature connectedness is linked to improved human welfare and actions for nature conservation and can be increased by direct contact with natural environments in adults living in the Global North. It has not been shown whether these relations are true across lifetimes and in the Global South, making it difficult to generalise about the effects of human-nature connectedness globally. Here, we conducted a cross-sectional study to examine and compare human-nature connectedness across ages in 1858 participants aged 3 to 87 years from two countries: France (N=1059) and Colombia (N= 799). We also investigated the links between human-nature connectedness, pro-environmental behaviours, well-being and two indicators of opportunity to experience nature (i.e., degree of urbanisation and forest cover around the participants' municipality of residence). Results show that human-nature connectedness is positively related to well-being and pro-environmental behaviours in both countries. Analyses revealed an age-related pattern of human-nature connectedness with a significant decline from childhood to the mid-teens in both countries. Overall, Colombian participants have a higher human-nature connectedness than French participants and individuals' human-nature connectedness was negatively linked to the urbanisation's indices in both countries. Here, we show that human-nature connectedness is linked to sustainable outcomes in a Global South country, just as it is in the Global North. Our study also suggests that increasing contact with nature during formative teenage years could mitigate the observed decline in human-nature connectedness. Future studies are warranted combining qualitative and quantitative measures related to human-nature connectedness, nature experiences, values and practices in relation to nature, in multiple countries from the global South. Our study indicates that enhancing human-nature connectedness could provide an additional tool for achieving sustainable targets globally, not just in highly-developed northern-hemisphere countries
