Results of the analysis of 50 interactions per corpus with respect to their directness, explicitness, certainty, and polarity. Results are given as fraction of analysed interactions that were not out-of-ontology (see Figure 3) and were identified as having a given property by two annotators. Cases where annotators disagreed were counted as half a point.
