UD_Old_French-SRCMF is a conversion of (part of) the SRCMF corpus (Syntactic Reference Corpus of Medieval French srcmf.org).

Main development happens on the GitLab of the Profiterole Project.

UD_Old_French-SRCMF consists in 10 texts spanning from 9th to 13th century. It includes 18 029 sentences and 199 699 tokens.

Sentences are annotated with the following metadata:

UD_Old_French-SRCMF results from the conversion of (part of) the SRCMF corpus (Syntactic Reference Corpus of Medieval French srcmf.org).

The SRCMF corpus results from the SRCMF project which took place in 2008-2012, funded by the ANR (France) and the DFG (Germany), and supervised by Sophie Prévost and Achim Stein.

The SRCMF project consisted in the manual syntactic annotation of 15 texts (251,000 tokens) from the 9th to 13th C. Part-of-speech tags were for most of them retrieved from the already existing tagging of the texts (stemming from: Base de Français Medieval, Lyon, ENS de Lyon, IHRIM Laboratory http://txm.bfm-corpus.org, and the Nouveau Corpus d’Amsterdam http://www.uni-stuttgart.de/lingrom/stein/corpus#nca)

The contributors to the SRCMF project were: Stein, Achim; Prévost, Sophie; Rainsford, Tom; Mazziotta, Nicolas; Bischoff Béatrice; Glikman, Julie; Lavrentiev, Alexei; Heiden, Serge; Guillot-Barbance, Céline; Marchello-Nizia, Christiane.

The whole SRCMF corpus (251,000 tokens) was converted into UD dependencies, but only 172,000 tokens have so far undergone a significant checking: the remaining 80,000 tokens will be added to UD_Old_French-SRCMF in a future release.

The conversion from the original SRCMF annotation to the SRCMF-UD annotation was done automatically both for the POS and the syntactic relations, thanks to a set of elaborated rules. Some 1,200 syntactic relations left unlabelled were then manually annotated (Sophie Prévost), and significant spot-checking occurred, focusing on potential difficulties (e.g. conj relation).

This conversion was achieved by Aurélie Collomb, in the frame of a internship funded by lab Lattice (Paris, CNRS, ENS & Université Sorbonne Nouvelle Paris 3, PSL & USPC), and supervised by Sophie Prévost, Isabelle Tellier and Kim Gerdes. Marine Courtin achieved the deposit of the files, and especially took in charge the validation of the corpus through the successive steps of the process.

A significant review of this initial release has been done on the occasion of the UD 2.6 release by Loïc Grobol and Sophie Prévost in the frame of the ANR PROFITEROLE project in order to improve the compliance of the corpus to UD guidelines. This includes both automatic corrections using the graph rewriting system GREW (Bonfante et al., 2018) and extensive manual corrections.

A significant import of data from the Base de français medieval has been done by Loïc Grobol, Alexei Lavrentiev and Sophie Prévost on the occasion of the UD 2.9 release. Most notably, this release adds punctuation tokens for most trees as well as around 350 new trees, consisting mostly of averbal sentences and fixes a number of conformity bugs with the UD guidelines.
