6 Conclusion and Future work
</SectionTitle>
    <Paragraph position="0"> We have noted that due to syntactic features such as smixut, the traditional definition of base NP chunks does not translate well to Hebrew and probably to other Semitic languages. We defined the notion of Simple NP chunks instead. We have presented a method for identifying Hebrew Simple NPs by supervised learning using SVM, providing another evidence for the suitability of SVM to chunk identification.</Paragraph>
    <Paragraph position="1"> We have also shown that using morphological features enhances chunking accuracy. However, the set of morphological features used should be chosen with care, as some features actually hurt performance.</Paragraph>
    <Paragraph position="2"> Like in the case of English, a large part of the errors were caused by conjunctions - this problem clearly requires more than local knowledge. We plan to address this issue in future work.</Paragraph>
