Annotation layers

UD scale: manual native — annotated by hand directly in UD; converted from manual — converted from manual annotation in another scheme; converted with corrections — converted and partly corrected by hand; automatic with corrections — automatic, with partial manual corrections; automatic — automatic; not available — the layer is absent.

Size

Tokens are surface tokens (Spanish vámonos is one), words are syntactic words (vamos + nos); multiword tokens are those split into several words; empty nodes are the N.M nodes of the enhanced graph.

Summary

UD Old_East_Slavic-Birchbark is based on the RNC Corpus of Birchbark Letters and includes documents written in 1025-1500 in an East Slavic vernacular (letters, household and business records, records for church services, spell against diseases, and other short inscriptions). The treebank is manually syntactically annotated in the UD 2.0 scheme, morphological and lexical annotation is a conversion of the original RNC annotation.

Introduction

The treebank is based on the historical Corpus of Birchbark Letters written in 1025-1500. It is part of the Russian National Corpus and includes documents written in an East Slavic vernacular (letters, household and business records, records for church services, spell against diseases, and other short inscriptions). The birchbark letters were found during archaeological excavations in Novgorod the Great, Staraya Russa, and other East Slavic cites and provide rare evidence of everyday writing in pre-Mongol East Slavic dialects. The fact that many documents are damaged and/or fragmented, together with the diversity of the spelling traditions presented in them, makes them an interesting case for linguistic analysis and historical NLP research.

The digital copies of the letters are reproduced online in a database available at gramoty.ru, where the hypotheses on tokenisation are also provided. The morphological analysis was originally done under the Russian National Corpus scheme for the Corpus of Birchbark Letters, which is mostly compatible with the RNC Old Russian scheme. Lemmatization reflects the later Old Russian spelling tradition. The morphological and lexical annotation of the UD Old_East_Slavic-Birchbark treebank is a conversion of this annotation that follows the mapping in (Lyashevskaya 2019). The sentence segmentation and the dependency annotation is originally done in the UD 2.0 scheme.
