Cette démonstration présente les avancées d’ACCOLÉ (Annotation Collaborative d’erreurs de traduction pour COrpus aLignÉs), qui en plus de proposer une gestion simplifiée des corpus et des typologies d’erreurs, l’annotation d’erreurs pour des corpus de traduction bilingues alignés, la collaboration et/ou supervision lors de l’annotation, la recherche de modèle d’erreurs dans les annotations, permet désormais d’annoter les Expressions Polylexicales (EPL) dans des textes monolingues en français, et d’accéder à l’annotation d’erreurs pour des corpus de traduction multicibles. Dans cet article, après un bref rappel des fonctionnalités d’ACCOLÉ, nous explicitons les fonctionnalités de chaque nouveauté.

We conduct in this work an evaluation study comparing offline and online neural machine translation architectures. Two sequence-to-sequence models: convolutional Pervasive Attention (Elbayad et al. 2018) and attention-based Transformer (Vaswani et al. 2017) are considered. We investigate, for both architectures, the impact of online decoding constraints on the translation quality through a carefully designed human evaluation on English-German and German-English language pairs, the latter being particularly sensitive to latency constraints. The evaluation results allow us to identify the strengths and shortcomings of each model when we shift to the online setup.

This article presents a resource that links WordNet, the widely known lexical and semantic database, and Arasaac, the largest freely available database of pictograms. Pictograms are a tool that is more and more used by people with cognitive or communication disabilities. However, they are mainly used manually via workbooks, whereas caregivers and families would like to use more automated tools (use speech to generate pictograms, for example). In order to make it possible to use pictograms automatically in NLP applications, we propose a database that links them to semantic knowledge. This resource is particularly interesting for the creation of applications that help people with cognitive disabilities, such as text-to-picto, speech-to-picto, picto-to-speech... In this article, we explain the needs for this database and the problems that have been identified. Currently, this resource combines approximately 800 pictograms with their corresponding WordNet synsets and it is accessible both through a digital collection and via an SQL database. Finally, we propose a method with associated tools to make our resource language-independent: this method was applied to create a first text-to-picto prototype for the French language.

La plateforme ACCOLÉ (Annotation Collaborative d’erreurs de traduction pour COrpus aLignÉs) propose une palette de services innovants permettant de répondre aux besoins modernes d’analyse d’erreurs de traduction : gestion simplifiée des corpus et des typologies d’erreurs, annotation d’erreurs efficace, collaboration et/ou supervision lors de l’annotation, recherche de modèle d’erreurs dans les annotations.

Corpus-based approaches to machine translation (MT) rely on the availability of parallel corpora. To produce user-acceptable translation outputs, such systems need high quality data to be efficiency trained, optimized and evaluated. However, building high quality dataset is a relatively expensive task. In this paper, we describe the data collection and analysis of a large database of 10.881 SMT translation output hypotheses manually corrected. These post-editions were collected using Amazon's Mechanical Turk, following some ethical guidelines. A complete analysis of the collected data pointed out a high quality of the corrections with more than 87 % of the collected post-editions that improve hypotheses and more than 94 % of the crowdsourced post-editions which are at least of professional quality. We also post-edited 1,500 gold-standard reference translations (of bilingual parallel corpora generated by professional) and noticed that 72 % of these translations needed to be corrected during post-edition. We computed a proximity measure between the differents kind of translations and pointed out that reference translations are as far from the hypotheses than from the corrected hypotheses (i.e. the post-editions). In light of these last findings, we discuss the adequation of text-based generated reference translations to train setence-to-sentence based SMT systems.
