Dialog and discourse clustering with semantic representations --------------------------------------------------- The DATCHA project is proposing a 1-year post-doc position on discourse and semantic analysis in the context of customer relationship management, at the University of Toulouse, France. The goal of the DATCHA project is to perform knowledge extraction from very large databases of WEB chat conversations between operators and clients in customer contact centers (technical and commercial). In this context, we want to predict customer satisfaction from the recorded interactions, and define similarity metrics for conversation analytics: (1) to define global features of conversations that can be useful to discriminate between them in a supervised setting, (2) to define a criterion on which to perform clustering of conversations, as an analytical tool, which in turn is useful : (3) for online customer support, where finding similar interactions (both from the content and the interaction point of view) can help an agent interacting with the customer, or help predict when an interaction is going in an undesirable direction and address the situation as soon as possible. Different combinations of dialog representations at the lexical, semantic and structural levels should be investigated along with similarity metrics. Evaluation of the task will be possible due to annotated data provided by our industrial partner Orange. We are looking for someone with a PhD in Natural Language Processing with a background in semantic or discourse parsing, and with a strong experience with supervised and unsupervised learning applied to NLP tasks. The work will take place within the Melodi group, a highly international team, at Toulouse University Computer science lab. Toulouse is located in the beautiful southwest of France, between the Atlantic Ocean, The Mediterranean Sea and the Pyrenees mountains.
