Our Research partnership with the CNRS

Located at the renowned Ecole Polytechnique (Paris, France) next to the new “Hi! Paris” AI research center, our technical team collaborates with the CNRS/LIMSI laboratory, one of the most advanced research teams in knowledge AI & virtual assistant for lifelong learning from the CNRS Saclay.

The CNRS LIMSI laboratory we are partnering with includes around 200 researchers, of which 70 specialized in Language Modeling & NLP. The CNRS LIMSI helps us constantly explore the benefits of the new state-of-the-art technologies as well as protect our intellectual property with patents (in collaboration with the Saclay SATT).

Who is & its incredibly efficient technology

Before deploying Professor Bob to the end users, he intensively learns about the concerned knowledge domain. He  learns from a staggering amount of knowledge sources, starting from our customer’s knowledge contents, but also adding specialized books and online trusted sources.

Professor Bob formalizes knowledge as questions & answers (Q&A) and for that purpose:

  • automatically generates thousands of questions thanks to innovative algorithms, 
  • builds from its knowledge sources several answers for each, 
  • scores the relevance of the Q&A pairs on various NLP metrics ; 

For instance, Professor Bob generates 30,000 questions on a knowledge domain, identifies 4 answers for each question & scores these 120,000  Q&A pairs. Then Bob extracts the best 3000 pairs.

What is

 This workflow to train ProfessorBob on a new knowledge domain involves a mix of our proprietary Machine Learning algorithms, optimized & pre-trained NLP language models and smart interfaces to fine-tune the workflow for the domain and validate the Q&A pairs.

At the end of this training process, Bob comes as a web_browser extension or can be integrated in your solution as an iFrame. Optionally, some APIs can collect learner analytics and personalize learning paths to each student.
