Zuckerman (1990) uses some simple plausible inference rules in her expla- nation system, in order to attempt to block in- correct plausible inferences, ... these rules rather than others in learning from descriptions. They simply provide a start- ing point for exploring how explanation generation may take into account possible...

Minimum Margin Selection (Min) This method is to select sentences that contain bun- setsu pairs which have smaller margin values of outputs of the classifier used in parsing. ... out in parsing. The differ- ence between AVG and MIN is that for AVG we use ∑ |f(x k )|/l where l is the number of calling Dep() in Figure 3 for the sentence s i instead of min |f (x k...
