Together with the mode of progression through the text, e.g., temporal or spatial, SE type distribution is a key factor for a reader or listener's intuitive recognition of the discourse mode of a text passage.
the automatic labeling of clauses with their SE type is a prerequisite for automatically identifying a passage's discourse mode, which in turn has promising applications in many areas of NLP, as the mode of a text passage has implications for the linguistic phenomena to be found in the passage.
