    <Paragraph position="0"> This paper investigates the use of NR modifiers in referring expressions to express certain semantic relations. This is a commonly used strategy by human authors, which has not been explored by an NLG system before. Our experiment shows that when the conditions for inferrability etc. are satisfied, certain relations can be expressed through an NR construction as well as a normally used hypotactic construction with little difference in semantics. This facilitates for an NLG system a way of expressing these semantic relations more concisely and subtly which could not be achieved by other means.</Paragraph>
    <Paragraph position="1"> Our experiment is restricted in many ways. One possible extension is to use more cue phrases to cover a wider range of cases for each semantic relation. In reality, the application domain should decide which relations need to be tested.</Paragraph>
