Natural Language Understanding

The Natural Language Understanding group works at the intersection of machine learning and natural language processing, with an emphasis on representation learning for the meaning of language, attention-based deep learning models, and structured prediction.

In our group, we model summarization, abstraction (textual entailment), machine translation, knowledge extraction, syntactic structure, and lexical semantics, among other natural language processing (NLP) problems. We develop deep learning models of the discovery and prediction of entities and their relations at multiple levels of representation for multiple tasks.

A novel architecture to improve syntactic analysis
research — last modified Apr 21, 2021

Demonstrating a significant improvements over the previous state-of-the-art results, James Henderson and Alireza Mohammadshahi of the Natural language understanding group propose a novel approach. Their work was presented during the 16th Conference of the European Chapter of the Association for Computational Linguistics (EACL) on April 21, 2021.

Importance of context in machine translation
research — Mar 18, 2021

Perfect understanding of a text is not possible without context. Same goes for a computer. It cannot do a good translation without understanding what is really defined in a text. At Idiap, Lesly Miculicich conducted research to make this possible through her thesis which she successfully defended last February.
