Dear colleagues, Please find hereafter an internship proposal. Feel free to transfer it to your M2 students.
Kind regards ---------------------------------------------------------------------------------------------------------------------------------- The LIG (Laboratoire d'Informatique de Grenoble) proposes the following Master 2 level internship: Title: Context-Aware Neural Machine Translation Evaluation Description: Context-Aware Neural Machine Translation (CA-NMT) [Tiedemann and Scherrer, 2017; Laubli et al., 2018; Miculicich et al., 2018; Maruf et al., 2019; Zheng et al., 2020; Ma et al. 2021; Lupo et al., 2022] is currently one of the main research axes in NLP, with strong impact on both academic and company research. CA-NMT systems are evaluated with both "average-quality-measuring" metrics such as BLEU [Papineni et al., 2002], and dedicated contrastive test suites [Voita et al., 2019; Muller&Rios 2018; Lopes et al., 2020]. The latter have been designed to measure specifically to which degree CA-NMT systems are able to exploit context while scoring sentences to be translated in context. Indeed the average translation quality measured by BLEU has been shown inadequate in this respect [Lupo et al., 2022]. When evaluating models with contrastive test suites however, models are only asked to score sentences and not to translate them. The ability of models to use context is thus only implicitly evaluated. With the work planned in this internship we would like to make a step ahead in the evaluation of CA-NMT systems. The idea is to exploit annotated data like those already used for [Muller&Rios 2018; Lopes et al., 2020] to explicitly involve discourse phenomena, such like coreferences and anaphora, in the evaluation procedure of CA-NMT models. Such evaluation procedure will allow possibly to design more accurate and adequate evaluation measures for "discourse-phenomena-aware" CA-NMT systems. Practical Aspects: In this internship the student will use Machine Learning and Deep Learning tools to automatically annotate parallel data (at least English-French, but possibly also English-German and other language pairs) used for NMT with discourse phenomena, as well as Neural Machine Translation tools for automatically generating translations that will be used for CA-NMT evaluation. Based on the annotation of discourse phenomena, we will design an adequate evaluation metric for CA-NMT systems, taking into account the capability of the system to exploit discourse phenomena. Finally, the evaluation metric will be tested by evaluating CA-NMT systems already available or trained from scratch at LIG by the student. Profile: Master 2 student level in computer science or NLP Interested in Natural Language Processing and Deep Learning approaches Skills in machine learning for probabilistic models Computer science skills: Python programming. Some knowledge of deep learning libraries such like Pytorch (Fairseq would be a plus). Data manipulation and annotation The internship may last from 5 up to 6 months, it will take place at LIG laboratory, GETALP team (http://lig-getalp.imag.fr/ <http://lig-getalp.imag.fr/>), starting from January/February 2022. The student will be tutored by Marco Dinarelli (http://www.marcodinarelli.it <http://www.marcodinarelli.it/>), andEmmanuelle Esperança-Rodier (https://lig-membres.imag.fr/esperane/ <https://lig-membres.imag.fr/esperane/>) Interested candidates must send a CV and a motivation letter to (both adresses) [email protected] <mailto:[email protected]>, [email protected] <mailto:[email protected]>.
