Active Learning for Interactive Relation Extraction in a French Newspaper’s Articles

no code implementations RANLP 2021 Cyrielle Mallart, Michel Le Nouy, Guillaume Gravier, Pascale Sébillot

Relation extraction is a subtask of natural langage processing that has seen many improvements in recent years, with the advent of complex pre-trained architectures.

Active Learning Relation Classification

Relation, es-tu l\`a ? D\'etection de relations par LSTM pour am\'eliorer l'extraction de relations (Relation, are you there ? LSTM-based relation detection to improve knowledge extraction )

no code implementations JEPTALNRECITAL 2020 Cyrielle Mallart, Michel Le Nouy, Guillaume Gravier, Pascale S{\'e}billot

Notre mod{\`e}le s{'}appuie sur le plus court chemin de d{\'e}pendances entre deux entit{\'e}s, mod{\'e}lis{\'e} par un LSTM et combin{\'e} avec les types des entit{\'e}s. Sur la t{\^a}che de d{\'e}tection de relations, nous obtenons de meilleurs r{\'e}sultats qu{'}un mod{\`e}le {\'e}tat de l{'}art pour la classification de relations, avec une robustesse accrue aux relations in{\'e}dites.

Rethinking deep active learning: Using unlabeled data at model training

1 code implementation19 Nov 2019 Oriane Siméoni, Mateusz Budnik, Yannis Avrithis, Guillaume Gravier

By systematically evaluating on a number of popular acquisition strategies and datasets, we find that the use of unlabeled data during model training brings a surprising accuracy improvement in image classification, compared to the differences between acquisition strategies.

Entity Extraction using GAN

Generative Adversarial Networks for Multimodal Representation Learning in Video Hyperlinking

no code implementations15 May 2017 Vedran Vukotic, Christian Raymond, Guillaume Gravier

We show that GANs can be used for multimodal representation learning and that they provide multimodal representations that are superior to representations obtained with multimodal autoencoders.
