Abstract

We describe ongoing work on the mapping between At-
tempto Controlled English (ACE) and OWL DL. ACE is a
well-studied controlled language, with a parser that converts
ACE texts into Discourse Representation Structure (DRS).
We describe a relatively direct mapping of a subset of the
DRS language to OWL DL. This mapping renders ACE an

names, definite noun phrases, pronouns, and variables. The
intention behind ACE is to minimize the number of syn-
tax and interpretation rules needed to predict the resulting
DRS, or for the end-user, the reasoning results. The small
number of ACE function words have a clear and predictable
