Modeling and extracting complex information from natural language text

October 27th 2020 from 11 AM to 12 PM (Paris time).
Online event.

The NoRDF Project is a scientific project at Télécom Paris, Institut Polytechnique de Paris that aims to model and extract complex information from natural language text. More precisely, we want to enrich knowledge bases with events, causation, precedence, stories, negation, and beliefs. In particular, we will investigate the expression of sentiment. We want to extract this type of information at scale from structured and unstructured sources, and we want to allow machines to reason on it. The project brings together research on knowledge representation, on reasoning, and on information extraction, and aims to be useful for applications such as fake news detection, the modeling of controversies, or the analysis of the e-reputation of a company.

In the first part of the talk, we will give a general overview of the project. In the second part of the talk, we will highlight the challenges for sentiment analysis in human-human and human-agent interactions.
