7 Conclusion
</SectionTitle>
    <Paragraph position="0"> I have presented a DL-bnsed parser for a small Ill,(l-style fragment of German. Most aspects of tile grammar and the parser have been modeled in a highly declarative way.</Paragraph>
    <Paragraph position="1"> Since the main motivalion for my tlresentation has been in show how an III&amp;quot;SG parser can be implemented in principle by using the inference functionality of a DE system, I have deliberately ignored any efficiency issues. It should be obvious, however, thai the parser can be further optimized to increase its perfornmnce, for example by integrating chart parsing techniques. We are currently testing tile performance of alternative implememalions of both the parser and the underlying DL system.</Paragraph>
    <Paragraph position="2"> One advantage of using DL as underlying formiflism is that in addition to the syntactic information modeled ill this paper, semantic and encyclopedic informalion can be easily integrated inlo tile presenled framework. Furlhermore, Preferential Default Description Logics can be used to model preference rules as weighted defaults, thereby obtaining intcq)relation as exception minimization. The l)arser presented in this llaper thus provides lhe basis for an homogeneous and formally well-founded approach to disambiguatltm based on Preferential Default Description Logics.</Paragraph>
