Data augmentation is an important method for evaluating the robustness of and enhancing the diversity of training data for natural language processing (NLP) models. In this paper, we present NL-Augmenter, a new participatory Python-based natural language (NL) augmentation framework which supports the creation of transformations (modifications to the data) and filters (data splits according to specific features). We describe the framework and an initial set of 117 transformations and 23 filters for a variety of NL tasks annotated with noisy descriptive tags. The transformations incorporate noise, intentional and accidental human mistakes, socio-linguistic variation, semantically-valid style, syntax changes, as well as artificial constructs that are unambiguous to humans. We demonstrate the efficacy of NL-Augmenter by using its transformations to analyze the robustness of popular language models. We find different models to be differently challenged on different tasks, with quasi-systematic score decreases. The infrastructure, datacards, and robustness evaluation results are publicly available on GitHub for the benefit of researchers working on paraphrase generation, robustness analysis, and low-resource NLP.

We share a French-English parallel corpus of Foursquare restaurant reviews, and define a new task to encourage research on Neural Machine Translation robustness and domain adaptation, in a real-world scenario where better-quality MT would be greatly beneficial. We discuss the challenges of such user-generated content, and train good baseline models that build upon the latest techniques for MT robustness. We also perform an extensive evaluation (automatic and human) that shows significant improvements over existing online systems. Finally, we propose task-specific metrics based on sentiment analysis or translation accuracy of domain-specific polysemous words.
This paper describes the systems that we submitted to the WMT19 Machine Translation robustness task. This task aims to improve MT’s robustness to noise found on social media, like informal language, spelling mistakes and other orthographic variations. The organizers provide parallel data extracted from a social media website in two language pairs: French-English and Japanese-English (one for each language direction). The goal is to obtain the best scores on unseen test sets from the same source, according to automatic metrics (BLEU) and human evaluation. We propose one single and one ensemble system for each translation direction. Our ensemble models ranked first in all language pairs, according to BLEU evaluation. We discuss the pre-processing choices that we made, and present our solutions for robustness to noise and domain adaptation.

Cet article présente en détails notre participation à la tâche 4 de SemEval2014 (Analyse de Sentiments associés aux Aspects). Nous présentons la tâche et décrivons précisément notre système qui consiste en une combinaison de composants linguistiques et de modules de classification. Nous exposons ensuite les résultats de son évaluation, ainsi que les résultats des meilleurs systèmes. Nous concluons par la présentation de quelques nouvelles expériences réalisées en vue de l’amélioration de ce système.

The objective of this paper is to describe the design of a dataset that deals with the image (i.e., representation, web reputation) of various entities populating the Internet: politicians, celebrities, companies, brands etc. Our main contribution is to build and provide an original annotated French dataset. This dataset consists of 11527 manually annotated tweets expressing the opinion on specific facets (e.g., ethic, communication, economic project) describing two French policitians over time. We believe that other researchers might benefit from this experience, since designing and implementing such a dataset has proven quite an interesting challenge. This design comprises different processes such as data selection, formal definition and instantiation of an image. We have set up a full open-source annotation platform. In addition to the dataset design, we present the first results that we obtained by applying clustering methods to the annotated dataset in order to extract the entity images.

Cet article présente l’intégration au sein d’un analyseur syntaxique (Xerox Incremental Parser) de règles spécifiques qui permettent de lier l’analyse grammaticale à la sémantique des balises XML spécifiques à un document donné. Ces règles sont basées sur la norme XPath qui offre une très grande finesse de description et permet de guider très précisément l’application de l’analyseur sur une famille de documents partageant une même DTD. Le résultat est alors être intégré directement comme annotation dans le document traité.

Cet article présente la normalisation de la sortie d’un analyseur robuste de l’anglais. Nous montrons quels sont les enrichissements que nous avons effectués afin de pouvoir obtenir à la sortie de notre analyseur des relations syntaxiques plus générales que celles que nous offrent habituellement les analyseurs robustes existants. Pour cela nous utilisons non seulement des propriétés syntaxiques, mais nous faisons appel aussi à de l’information de morphologie dérivationnelle. Cette tâche de normalisation est menée à bien grâce à notre analyseur XIP qui intègre tous les traitements allant du texte brut tout venant au texte normalisé. Nous pensons que cette normalisation nous permettra de mener avec plus de succès des tâches d’extraction d’information ou de détection de similarité entre documents.
