5 Conclusion and Future Research
</SectionTitle>
    <Paragraph position="0"> In this paper we studied cascaded grammatical relations assignment. We showed that even the use of imperfect modules improves the overall result of the cascade.</Paragraph>
    <Paragraph position="1"> In future research we plan to also train our classifiers on imperfectly chunked material. This enables the classifier to better cope with systematic errors in train and test material. We expect that especially an improvement of the  adverbial function assignment will lead to better GR assignment.</Paragraph>
    <Paragraph position="2"> Finally, since cascading proved effective for GR assignment we intend to study the effect of cascading different types of XP chunkers on chunking performance. We might e.g. first find ADJP chunks, then use that chunker's output as additional input for the NP chunker, then use the combined output as input to the VP chunker and so on. Other chunker orderings are possible, too. Likewise, it might be better to find different grammatical relations subsequently, instead of simultaneously.</Paragraph>
