On Developing a Controlled Natural Language for Reasoning with Defeasible
We present an approach to reasoning with knowledge bases comprised of strict
and defeasible rules over literals using a controlled natural language
(CNL), which is an adaptation of the AceRules system. The CNL expressions of
rules are plausible, parsed, and semantically represented. The semantic
representations are passed to an inference engine to accurately generate
answer sets; the inference engine is based on a "direct" approach to
evaluating defeasible knowledge bases and employs techniques from formal
argumentation theory. A verbaliser expresses the results of the answer sets
in natural language, which facilitates understanding. The approach is
illustrated with working examples. We outline problems and prospects.
