Natural Language Understanding

The Idiap NLU group was created in September 2017 under the direction of James Henderson, in part as a continuation of the previous Natural Language Processing group which was lead by Andrei Popescu-Belis. The NLU group continues work on how semantic and discourse processing of text and dialog can improve statistical machine translation and information indexing, with a recent focus on neural machine translation and attention-based deep learning models. This fits well with the NLU group's new research direction of neural network structured prediction and representation learning for modeling the syntax and semantics of text and speech, including modeling abstraction (textual entailment) and summarization.

Idiap has a new opening for an Internship position in Natural Language Processing on DNN-based coreference models
education — Dec 22, 2016

Co-reference is the relation between words or phrases in a text that refer to the same entity. DNNs have been successfully applied to a variety of NLP tasks, but for coreference resolution such approaches have shown limited improvement and a suitable model remains to be found. The goal of this internship is to go beyond classifiers that decide whether a pair of phrases is co-referent or not, and instead learn to represent, in the output layer, each of the entities of a text. In collaboration with a PhD student and a postdoc, the model will be applied to document-level machine translation. The work will thus relate to the EU SUMMA and SNSF MODERN projects.

Idiap submission to MediaEval 2013 ranked first for the video hyperlinking task
research — Nov 26, 2013

The Idiap NLP group has participated in the search and hyperlinking task at the MediaEval 2013 evaluation campaign. The NLP group was ranked first out of eleven participants on the hyperlinking task (finding video segments related to a given one) and third out of seven on the keyword video search task.
