## Summary

> A small treebank of Upper Sorbian based mostly on Wikipedia, partly also on other Sorbian websites.

## Introduction

> The Upper Sorbian sentences are taken from the W2C corpus (Martin Majliš), which was further manually filtered, morphologically and syntactically annotated by Daniel Zeman; lemmatization by Anna Nedoluzhko.
> 
> Paragraphs in the W2C corpus were shuffled but since UD v2.17, we restored their original order where possible, and added document boundaries and ids. Articles from Wikipedia have document ids starting with "wiki-". The remaining texts come mostly from the web of the Sorbian Institute, some of them also from the websites of Sorbian-speaking municipalities.
