We present a dialogue annotation scheme for both spoken and written interaction, and compare its application to a telephone transaction corpus and an email corpus. We train classifiers for both corpora, comparing regular SVM and structured SVM against a heuristic baseline. We provide a novel application of structured SVM to predicting relations between instance pairs.
