1. What are the contributions mentioned in the paper "Multifunctionality in dialogue" ?
This paper studies the multifunctionality of dialogue utterances, i. e. the phenomenon that utterances in dialogue often have more than one communicative function.. The multifunctionality of dialogue utterances is studied by ( 1 ) redefining the notion of ‘ utterance ’ in a rigorous manner ( calling the revised notion ‘ functional segment ’ ), and ( 2 ) empirically investigating the multifunctionality of functional segments in a corpus of dialogues, annotated with a rich, multidimensional annotation schema.

2. What is the important effect of using functional segments as the unit of analysis?
For the study of multifunctionality in dialogue, the most important effect of using functional segments as the unit of analysis is that sequential multifunctionality is eliminated and that only simultaneous multifunctionality remains at the level of functional segments.

3. What is the effect of a sequential multifunctionality on a dialogue?
While segmenting a dialogue into utterances rather than turns has the effect of eliminating sequential multifunctionality, simultaneous multifunctionality may still occur, not at the level of turns but at that of utterances.

4. What is the advantage of a structured tag set?
A hierarchical organisation in the tag set may also be advantageous for automatic annotation and for achieving annotations which are compatible though not identical with those of human annotators.
