The main message conveyed by the results from Table 14 is that the output from the models built for ungraded LE indeed cannot be used as an estimate of graded LE.
the relative entropy or the measure of distributional inclusion between two concepts can be used to reliably detect which concept is the hypernym in the directionality task, or to distinguish between LE and other relations in the detection task, but it leads to a poor global estimate of the LE strength for graded LE experiments.
