Conversation proceeds through dialogue moves or acts, and dialog act annotation can aid the design of artificial dialog. While many dialogs are task-based or instrumental, with clear goals, as in the case of a service encounter or business meeting, many are more interactional in nature, as in friendly chats or longer casual conversations. Early research on dialogue acts focussed on transactional or task-based dialogue but work is now expanding to social aspects of interaction. We review how dialog annotation schemes treat non-task elements of dialog -- greeting and leave-taking sequences in particular. We describe the collection and annotation, using the ISO Standard 24617-2 Semantic annotation framework, Part 2: Dialogue acts, of a corpus of 187 text dialogues and study the dialog acts used in greeting and leave-taking.
