GermEval 2015: LexSub -- A Shared Task for German-language Lexical Substitution

Lexical substitution is a task in which participants are given a word in a short context and asked to provide a list of synonyms appropriate for that context. This paper describes GermEval 2015: LexSub, the first shared task for automated lexical substitution on German-language text. We describe the motivation for this task, the evaluation methods, and the manually annotated data set used to train and test the participating systems. Finally, we present an overview and discussion of the participating systems' methodologies, resources, and results.
