In this work, we present the first results of a project aiming at a Finnish Proposition Bank, an annotated corpus of semantic roles. The annotation is based on an existing treebank of Finnish, the Turku Dependency Treebank, annotated using the well-known Stanford Dependency scheme. We describe the use of the dependency treebank for PropBanking purposes and show that both annotation layers present in the treebank are highly useful for the annotation of semantic roles. We also discuss the specific features of Finnish influencing the development of a PropBank as well as the methods employed in the annotation, and finally, we present preliminary evaluation of the annotation quality.
