CONCLUSION
</SectionTitle>
    <Paragraph position="0"> AS for the scheme of software environment to meet the requirements for a design of NLU system, we have proposed a five layered environment which has hierarchical, multi-level structures of software systems. The scheme is called MLSE and these characteristics are following: i. There exists the core language which served as the assembly language in NLU systems. In this case, LISP is selected. 2. In case of designing the NLU systems, the utility functions such as structural and zoom editor are some of the important functions. In this respect, LISP is already developed in these functions. These facilities are important to develop the module packages.</Paragraph>
    <Paragraph position="1"> 3. There exists a number of NLU module packages which may be further used as the components of tools.</Paragraph>
    <Paragraph position="2"> We believe that these three characteristics are applicable for designing NLU system.</Paragraph>
