Neurocorpus: neural translations and augmented corpora
(aspects of a roadmap for corpus linguists in NMT)

This exploratory project is intended as a proof of concept for a resubmission to the Université de Paris émergence 2020 call for projects. The Neurocorpus project received 5 000 dollar credits on Google Computing Cloud.

Background

Neural machine translation (NMT) is a fairly recent approach (Kalchbrenner & Blunsom, 2013; Bahdanau et al, 2014; Sutskever et al., 2014), which has not only significantly improved machine translation performance, but has radically changed the intellectual landscape in the field. By reviving a formalism of the 1980s, it literally buried statistical translation, which was too technical to be accessible to linguists by training. This considerably changes the situation for corpus linguists who have a long tradition of tools. Provided that they learn a programming language, it once again allows corpus linguists to be potential actors in the field, no longer just expert spectators of machine translation errors, and to contribute to the analysis of neural processes, possibly improving results in the processing of system input and output data. Since no one completely understands what the neural network does yet, the exploration of machine translation by linguists makes sense again, if only in a behaviorist approach to neural network. In a word, the generalization of deep learning gives back all its importance to linguists’ intuitions, especially in the processing of input data (see Valette (2015), who showed for sentiment analysis that the procedure of exclusion of pronouns, standard among computer scientists, considerably deteriorates the results obtained). Around this project, we have formed a team that brings together experts in the field of language and statistical learning. Beyond scientific production, the objective is to develop a demonstrator: a specialized translation engine for medical English that integrates the project’s progress.

Work Packages

We have structured our project around two work packages.
1. the exploration of the black box
This fundamental research section seeks to understand and interpret (Montavon et al., 2018) what the neural network does: How can we learn to translate from input corpus and algorithms? The most ambitious and risky objective is to contribute to the study of the impact of neural network architecture on NMT performance and to develop a behaviourist approach to RNNs. Deliverables: articles will be submitted to conferences in the field, such as ACL, EMNLP or WMT or in its satellite events (blackbox).
2. Augmented corpora (case studies)
We have selected types of corpora to study input issues with annotation, including “augmented corpora” by several layers of syntax annotation with the collaboration of other linguists.
