    <Paragraph position="0"> We have presented a unified approach to the problem of automatic preposition interpretation. The extrinsic evaluation result in the context of a QA system encourages us to continue work in the following directions. The PP interpretation rules are to be transferred to other languages. We have already started for English. The transfer on the level of preposition readings (or PP rules) is much easier than translating prepositions. Moreover, the coverage and quality of all three knowledge resources should be further extended. For example, we want to analyze why certain PP interpretation rules have rarely succeeded during corpus parsing.</Paragraph>
    <Paragraph position="1"> Extrinsic evaluations on larger and more difficult question sets for QA systems and evaluations in other NLP applications might help to focus further research.</Paragraph>
