SOFTWARE resources

Annotation tools:

EZCAT: an Easy Conversation Annotation Tool:  annotation tool in conversations developed by Gaël Guibon during his post-doc in collaboration with SNCF

noytext : a text annotation web-application developed by Luis Gasco during his research stay at Telecom-ParisTech for opinion analysis in social network.

Models and software:

LogiTorch is a PyTorch-based library for logical reasoning on natural language developed by Chadi Helwé during his Ph.D., it consists of:

  • Textual logical reasoning datasets
  • Implementations of different logical reasoning neural architectures
  • A simple and clean API that can be used with PyTorch Lightning

dialign : a software developed during his post-doc  by Guillaume Dubuisson-Duplessis for the computation of generic measures of verbal alignment in dyadic dialogue based on sequential pattern mining

ProtoSeq: a model developed by Gaël Guibon during his post-doc for few-shot emotion recognition in conversation with sequential prototypical networks

Evaluation metrics

BaryScore, InfoLM: new automatic metrics developed by Pierre Colombo during his PhD for evaluating Natural Language Generation


Meta-learning demo: a demo developed by Gaël Guibon during his post-doc in collaboration with SNCF on meta-learning for emotion recognition in conversations

Corpora and benchmarks


The Sequence labellIng evaLuatIon benChmark fOr spoken laNguagE (SILICONE) benchmark is a collection of resources for training, evaluating, and analyzing natural language understanding systems specifically designed for spoken language. All datasets are in the English language and cover a variety of domains including daily life, scripted scenarios, joint task completion, phone call conversations, and television dialogues. Some datasets additionally include emotion and/or sentiment labels.

POTUS corpus

The POTUS Corpus is composed of high-quality audio-video files of political addresses to the American people. The database is divided into two sets:

  • speeches of former president Barack Obama to the American people.
  • videos of these same speeches given by a virtual agent named Rodrigue. The ECA reproduces the original address as closely as possible using social signals automatically extracted from the original one.

Both are annotated for social attitudes, providing information about the stance observed in each file. It also provides the social signals automatically extracted from Obama’s addresses used to generate Rodrigue’s ones.

SAFE Corpus

Situation Analysis in a Fictional and Emotional Corpus: The SAFE corpus contains 7 h of audiovisual sequences in English extracted from fiction movies from various genres (action, thriller, historical drama). The movies have been chosen according to the following criteria: they illustrate various threat situations and contain realistic portrayals of strong emotional manifestations. A corpus sequence corresponds to a movie section illustrating one type of situation – kidnapping, physical aggression, flood, etc. The corpus was annotated according to a task-dependant and audio-based annotation strategy with various levels of accuracy defined in order to describe emotional diversity in fiction
