    <Paragraph position="0"> In this paper, the three features of the Japanese-language interface KID were described.</Paragraph>
    <Paragraph position="1"> KID has both a simple mechanism of parsing and modularized grammar rules, so the parser is highly extendable. The semantic interpretation has clear principles based on the structure of the world model and syntactic information of the input sentence. Thus, the different levels of robustness are achieved by the adequate portion of the parser for dealing with the errors or ellipses. The world model integrates the domain-dependent knowledge separately. The user only has to customize the world model to a specific application. This customization is supported by the world model editor which provides various levels of user interfaces to make the world model editing easy for various users.</Paragraph>
    <Paragraph position="2"> KID is now implemented as a front-end system for the relational database system (Makinouchi, 83). KID is implemented in Utilisp (Chikayama, 81), a dialect of Lisp. The morphological analyzer is 0.7 ksteps, the model-based parser is 2.3 ksteps, and retriever is 2.2 ksteps. The grammatical rule is 2.7 kstepe written in a rule description language, and is made up of 70 packets. KID uses several tools and utilities.</Paragraph>
    <Paragraph position="3"> The modeling system REALM is 2 ksteps, the world model editor is 1.3 ksteps, the window system is 1.7 ksteps, and the knowledge-based programming system, Minerva, is 3.5 ksteps.</Paragraph>
    <Paragraph position="4"> We have several plans for future development.</Paragraph>
    <Paragraph position="5"> We will expand the system to accept not only retrieval sentences but also insertion, deletion, update, statistical analysis, and graphic operation. The parser coverage will be extended to accept wider expressions, including parallel phrases and sentences.</Paragraph>
