In this paper we present the first Universal Dependency Treebank for Latvian. Latvian UD Treebank contains approx. 1 thousand sentences. It has been created from Latvian Treebank newswire texts with the help of an automatic conversion. This resource is an important prerequisite for integrating Latvian in various international language processing frameworks and making Latvian data more welcoming to international researchers. This paper also includes an analysis of the main conversion problems and describes known discrepancies between annotations in Latvian UD Treebank and Universal Dependency annotation guidelines.
