    <Paragraph position="0"> We have bccn developing a Japanese-to-English madfine lrauslation syslem called ALT-J/E (lkehm-a et al., 1987). In ALT-J/E, Japanese sentence analysis is performed based on lhe wdency slruclure for the predicalc of the input sentence. ALT-J/E c~m trm~slate several special Japm~ese constntclions such as predicate idioms and funclion verb expressions (Oku, 1992).</Paragraph>
    <Paragraph position="1"> The Jap~mese double-subject conslntclion was nol handled well by the original ALT-J/E. This paper describes a melhod lbr mmlyzing a Japanese double-subject construction having an ad.i eclivet)rcdicate bascd on Ihe valency structure.</Paragraph>
    <Paragraph position="2"> Simple sentences normally have only one sub.icctivc case in most languages. However, it is possible for many Japlmese adjectives (and so me verbs) to dominate two surface subjective cases within a simple sentence.</Paragraph>
    <Paragraph position="3"> Such sentence structure is called lhe double-subject construction. JEiDA (Ihe Japan Elcclronic Industry Development Associalion) has issued evaluation st~mdards for machine lnmslation systems (JEIDA, 1995). ~Ihe main aim of lhese standards is to establish objective test sets for machine translation system evaluation. Therefore, they include ahnost of all linguislic phenomena flu,l the systems have to process.</Paragraph>
    <Paragraph position="4"> In lhc slandards, the double-subject eonslruclion is listed as one of the conslruclions lhat arc difficult lo process successfidly.</Paragraph>
    <Paragraph position="5"> Many Japmlesephilologistshavesludicdthc double-subject construction because it is necessary to reveal the synlaclic or scmmltic structure of lhis construction if wc are to establish a syntactic or sem~ullic lheo~, lor the Japanese language (lshigami, 1977) (Kuno, 1973) (Mikami, 1961)). However, there arc a few sludies for processing this conslmction from lhe point of view of computational linguislics or engineering (Mttrala, 1990). ~llmrelbrc, lhc aim of lhis paper is to discuss a melhod for ;malyzing lhc Japanese double-subject constnlction havhlg an adjective predicate from lhe point of view of engineering.</Paragraph>
