9 Conclusions
</SectionTitle>
    <Paragraph position="0"> In this paper, we have concentrated on problems concerned with 'understanding and translation' and have tried to clarify that the aspects of 'understanding' relevant to MT are different from those in conventional NLU researches and their application fields. The relation~ships between linguistic expressions and their understanding results are not as straightforward as most researchers in NLU have assumed. Though most researches in NLU have focused on single aspects of understanding which are defined by 'internal processing', we have to treat almost all aspects of 'understanding texts' in MT, which are mutually intertwined in a complicated manner and have to be integrated into single computationally unified frameworks. Though this is an extremely hard task, the difficulties seem to be deeply related both to 'understanding texts' in a true sense and to the essential properties of natural language. We would also like to claim that it is time to integrate these two fields with their different histories and different techniques, MT and NLU, and so to start to clarify what 'understanding texts' really means.</Paragraph>
