Summary

UD_French-Sequoia is an automatic conversion of the Sequoia Treebank corpus French Sequoia corpus.

Introduction

UD_French-Sequoia is an automatic conversion of the Sequoia Treebank corpus French Sequoia corpus. The conversion was done with the Grew software and the Graph Rewriting System described here.

Origin

The first version of the Sequoia Corpus was presented in (Candito & Seddah, 2012)

Splitting

The whole corpus contains 70,624 tokens in 3,099 sentences.

In UD_French-Sequoia, data were randomly split into:

  • fr_sequoia-ud-test.conllu: 10,050 tokens in 456 sentences
  • fr_sequoia-ud-dev.conllu: 10,013 tokens in 412 sentences
  • fr_sequoia-ud-train.conllu: 50,561 tokens in 2,231 sentences

Genres

The original sentences of the corpus are taken from:

  • French Europarl (sent_id prefix: Europar.550)
  • Wikipédia Fr (sent_id prefix: frwiki_50.1000)
  • Newspaper Est Républicain (sent_id prefix: annodis.er)
  • European Medicines Agency (sent_id prefix: emea-fr-dev and emea-fr-test)

Acknowledgments

The conversion has been performed by Bruno Guillaume with the Graph Rewriting System described here developed by Bruno Guillaume and Guy Perrier.

The Sequoia Corpus was presented in (Candito & Seddah, 2012) and revised later, notably during the project of deep annotation described in (Candito & al. 2014) and (Perrier & al. 2014).
