In this paper, we propose an annotation schema for the discourse analysis of Wikipedia Talk pages aimed at the coordination efforts for article improvement. We apply the annotation schema to a corpus of 100 Talk pages from the Simple English Wikipedia and make the resulting dataset freely available for download1 . Furthermore, we perform automatic dialog act classification on Wikipedia discussions and achieve an average F1 -score of with our classification pipeline. | Behind the Article Recognizing Dialog Acts in Wikipedia Talk Pages Oliver Ferschkf- Iryna Gurevych and Yevgen Chebotar f Ubiquitous Knowledge Processing Lab UKP-DIPF German Institute for Educational Research and Educational Information ị Ubiquitous Knowledge Processing Lab UKP-TUDA Department of Computer Science Technische Universitat Darmstadt http Abstract In this paper we propose an annotation schema for the discourse analysis of Wikipedia Talk pages aimed at the coordination efforts for article improvement.
