Comparing Statistical and Neural Models for Learning Sound Correspondences

1 code implementation LREC 2020 Cl{\'e}mentine Fourrier, Beno{\^\i}t Sagot

Cognate prediction and proto-form reconstruction are key tasks in computational historical linguistics that rely on the study of sound change regularity.

Methodological Aspects of Developing and Managing an Etymological Lexical Resource: Introducing EtymDB-2.0

1 code implementation LREC 2020 Cl{\'e}mentine Fourrier, Beno{\^\i}t Sagot

Diachronic lexical information is not only important in the field of historical linguistics, but is also increasingly used in NLP, most recently for machine translation of low resource languages.

What Does BERT Learn about the Structure of Language?

1 code implementation ACL 2019 Ganesh Jawahar, Beno{\^\i}t Sagot, Djam{\'e} Seddah

BERT is a recent language representation model that has surprisingly performed well in diverse language understanding benchmarks.

ELMoLex: Connecting ELMo and Lexicon Features for Dependency Parsing

no code implementations CONLL 2018 Ganesh Jawahar, Benjamin Muller, Amal Fethi, Louis Martin, {\'E}ric Villemonte de la Clergerie, Beno{\^\i}t Sagot, Djam{\'e} Seddah

We augment the deep Biaffine (BiAF) parser (Dozat and Manning, 2016) with novel features to perform competitively: we utilize an indomain version of ELMo features (Peters et al., 2018) which provide context-dependent word representations; we utilize disambiguated, embedded, morphosyntactic features from lexicons (Sagot, 2018), which complements the existing feature set.

Improving neural tagging with lexical information

no code implementations WS 2017 Beno{\^\i}t Sagot, H{\'e}ctor Mart{\'\i}nez Alonso

Neural part-of-speech tagging has achieved competitive results with the incorporation of character-based and pre-trained word embeddings.

An Open-Source Heavily Multilingual Translation Graph Extracted from Wiktionaries and Parallel Corpora

no code implementations LREC 2014 Val{\'e}rie Hanoka, Beno{\^\i}t Sagot

This paper describes YaMTG (Yet another Multilingual Translation Graph), a new open-source heavily multilingual translation database (over 664 languages represented) built using several sources, namely various wiktionaries and the OPUS parallel corpora (Tiedemann, 2009).


A language-independent and fully unsupervised approach to lexicon induction and part-of-speech tagging for closely related languages

no code implementations LREC 2014 Yves Scherrer, Beno{\^\i}t Sagot

In this paper, we describe our generic approach for transferring part-of-speech annotations from a resourced language towards an etymologically closely related non-resourced language, without using any bilingual (i. e., parallel) data.

A Language-independent Approach to Extracting Derivational Relations from an Inflectional Lexicon

no code implementations LREC 2014 Marion Baranes, Beno{\^\i}t Sagot

In this paper, we describe and evaluate an unsupervised method for acquiring pairs of lexical entries belonging to the same morphological family, i. e., derivationally related words, starting from a purely inflectional lexicon.

Evaluating and improving syntactic lexica by plugging them within a parser

no code implementations LREC 2012 Elsa Tolone, Beno{\^\i}t Sagot, {\'E}ric Villemonte de la Clergerie

We present some evaluation results for four French syntactic lexica, obtained through their conversion to the Alexina format used by the Lefff lexicon, and their integration within the large-coverage TAG-based FRMG parser.


Cleaning noisy wordnets

no code implementations LREC 2012 Beno{\^\i}t Sagot, Darja Fi{\v{s}}er

Manual evaluation of the results shows that by applying a threshold similar to the estimated error rate in the respective wordnets, 67{\%} of the proposed outlier candidates are indeed incorrect for French and a 64{\%} for Slovene.
