5 Conclusions
</SectionTitle>
    <Paragraph position="0"> In this paper, a new hybrid disambiguation method which uses PP interpretation rules and  statistics about attachment and interpretation in an annotated corpus was described. It yields results with competitive correctness for both the PP attachment problem and the PP interpretation problem.</Paragraph>
    <Paragraph position="1"> Some questions had to be left open, e.g., a nontrivial reading disambiguation 11 for candidate mothers and sister NPs. Questions concerning the requisite manual work (maintaining rules and some parts of annotating corpora) arise: How much!does this work pay off and how could more of this work be automated? The disambiguation method should be evaluated for larger corpora (more sentences, more prepositions) in future research. The ongoing use of the disambiguation method in natural language interfaces will provide valuable feedback.</Paragraph>
    <Paragraph position="2"> llThis is closely related to the problem of word sense disambiguation; currently, this disambiguation is based on frequencies.</Paragraph>
    <Paragraph position="3"> hybrid disambiguation</Paragraph>
