In the ICSI Meeting Recorder Dialog Act (MRDA) Corpus, which label(s) correspond to the Filler class?
I have read a couple of article (e.g. (1)) saying there exist a widely applied classmap that maps the dialog acts onto 5 distinct classes: statements (S), questions (Q), backchannels (B), fillers (F) and disruptions (D).
However, looking at the data set official manual (2) and paper (3), I fail to see which label(s) should be regarded as fillers:
