In an attempt to set the ground for more comparable research in the area, a standard for dialog act annotation was developed (Bunt et al., 2012;Bunt et al., 2017).
annotating dialogs according to this standard is an exhaustive process, especially since the annotation does not consist of a single label, which in the standard nomenclature is called a communicative function, but rather of a complex structure which includes information regarding the semantic dimension of the dialog act and relations with other segments, among others.
