An End-to-End Approach for Full Bridging Resolution

no code implementations ACL (CODI, CRAC) 2021 Joseph Renner, Priyansh Trivedi, Gaurav Maheshwari, Rémi Gilleron, Pascal Denis

We demonstrate the performance of an end-to-end transformer-based higher-order coreference model finetuned for the task of full bridging.

Integrating knowledge graph embeddings to improve mention representation for bridging anaphora resolution

no code implementations COLING (CRAC) 2020 Onkar Pandit, Pascal Denis, Liva Ralaivola

Specifically, we convert the external knowledge source (in this case, WordNet) into a graph, and learn embeddings of the graph nodes of low dimension to capture the crucial features of the graph topology and, at the same time, rich semantic information.

A Tale of Two Laws of Semantic Change: Predicting Synonym Changes with Distributional Semantic Models

no code implementations30 May 2023 Bastien Liétard, Mikaela Keller, Pascal Denis

Another related question is whether and how lexical relations over pairs of words, such as synonymy, change over time.

Fair Without Leveling Down: A New Intersectional Fairness Definition

no code implementations21 May 2023 Gaurav Maheshwari, Aurélien Bellet, Pascal Denis, Mikaela Keller

In this work, we consider the problem of intersectional group fairness in the classification setting, where the objective is to learn discrimination-free models in the presence of several intersecting sensitive groups.

Exploring Category Structure with Contextual Language Models and Lexical Semantic Networks

no code implementations14 Feb 2023 Joseph Renner, Pascal Denis, Rémi Gilleron, Angèle Brunellière

Recent work on predicting category structure with distributional models, using either static word embeddings (Heyman and Heyman, 2019) or contextualized language models (CLMs) (Misra et al., 2021), report low correlations with human ratings, thus calling into question their plausibility as models of human semantic memory.

Fair NLP Models with Differentially Private Text Encoders

1 code implementation12 May 2022 Gaurav Maheshwari, Pascal Denis, Mikaela Keller, Aurélien Bellet

Encoded text representations often capture sensitive attributes about individuals (e. g., race or gender), which raise privacy concerns and can make downstream models unfair to certain groups.

A Probabilistic Model for Joint Learning of Word Embeddings from Texts and Images

no code implementations EMNLP 2018 Melissa Ailem, Bo-Wen Zhang, Aurelien Bellet, Pascal Denis, Fei Sha

Our approach learns textual and visual representations jointly: latent visual factors couple together a skip-gram model for co-occurrence in linguistic data and a generative latent variable model for visual data.

Delexicalized Word Embeddings for Cross-lingual Dependency Parsing

no code implementations EACL 2017 Mathieu Dehouck, Pascal Denis

This paper presents a new approach to the problem of cross-lingual dependency parsing, aiming at leveraging training data from different source languages to learn a parser in a target language.

French TimeBank: An ISO-TimeML Annotated Reference Corpus

no code implementations Proceedings of the 49th Annual Meeting of the Association for Computational Linguistics: Human Language Technologies 2011 André Bittar, Pascal Amsili, Pascal Denis, Laurence Danlos

This article presents the main points in the creation of the French TimeBank (Bittar, 2010), a reference corpus annotated according to the ISO-TimeML standard for temporal annotation.
