Cooking Up a Neural-based Model for Recipe Classification

no code implementations LREC 2020 Elham Mohammadi, Nada Naji, Louis Marceau, Marc Queudot, Eric Charton, Leila Kosseim, Marie-Jean Meurs

In this paper, we propose a neural-based model to address the first task of the DEFT 2013 shared task, with the main challenge of a highly imbalanced dataset, using state-of-the-art embedding approaches and deep architectures.

Improving Entity Linking using Surface Form Refinement

no code implementations LREC 2014 Eric Charton, Marie-Jean Meurs, Ludovic Jean-Louis, Michel Gagnon

The approach extends the surface form coverage of our entity linking system, and rewrites or reformulates misspelled mentions (entities) prior to starting the annotation process.

A disambiguation resource extracted from Wikipedia for semantic annotation

no code implementations LREC 2012 Eric Charton, Michel Gagnon

The Semantic Annotation (SA) task consists in establishing the relation between a textual entity (word or group of words designating a named entity of the real world or a concept) and its corresponding entity in an ontology.
