Hi Matt --

Another way of increasing the amount of trust is to provide explanations, in
English, automatically derived from the proofs that an agent carries out.

A serendipitous feature is that the explanations start out with headlines,
and then go progressively into finer details.  This aspect is particularly
useful for explanations over RDF,  where there may be many more steps than
for similar deductions over n-ary predicates, n >> 3 .  The example [1]
illustrates this.

The explanations can be automatically hypertexted for ease of navigation.

The explanations can also be abductive, for cases where an expected answer
is not found.

This is what is done in the system online at the site below.
