8 Conclusions and Further Work
</SectionTitle>
    <Paragraph position="0"> We have shown that a digraph analysis of preposition definitions provides a useful organizing principle for analyzing and understanding the meanings of prepositions. The definitions themselves provide sufficient information for developing an inheritance hierarchy within a typed-feature structure arrangement and also provide a rich set of criteria for disambiguating among the many senses. By incorporating these criteria in a text processing system, it is possible to develop semantic triples that characterize intrasentential relationships among discourse entities. Further, the characterization of meanings may prove useful in identifying theta roles implied by the ending prepositions of transitive verb definitions Much work remains to be done to develop the full set of information for all prepositions. We believe we have established a suitable framework for carrying out this work.</Paragraph>
