Note#1: the unknowns with initiale lower-case letter denote some full-size unknown words but often words which have been cut due to bad interpreation of PDF multi-columns by PDFBox.

Note#2: a paper without any content (i.e. without any body) is not taken in the pipeline. This situation may be the consequence of a processing problem or may be it is an invited presentation without any text.In constrast, a paper without abstract is taken.

Note#3: a paper without any content holds an entry in the metadata, and normally, each paper has an entry in the metadata.

Note#4: the combined evaluation is computed as: 2*EvalNoise*EvalSilence / EvalNoise+EvalSilence
