PENG Light is a controlled natural language designed to write unambiguous specifications that can be translated automatically via discourse representation structures into a formal target language. Instead of writing axioms in a formal language, an author writes a specification and the associated background axioms directly in controlled natural language. In this paper, we first review the controlled natural language PENG Light and show how a discourse representation structure is generated for sentences written in PENG Light. We then discuss two different solutions of how discourse representation structures can be implemented for coordinated structures. Finally, we show how an efficient implementation of coordinated structures combined with a suitable parsing strategy affects the parsing performance of the controlled natural language.
