1. Introduction
</SectionTitle>
    <Paragraph position="0"> When we build a machine translation system for dialogues, we must face a lot of contextual-phenomena such as ellipses, anaphoras and pro-forms. In a dialogue these phenomena are more complicated because of many disturbances such as interruptions, inserted sentences and utterance disorder. The phenomena have not been treated on the computer though these phenomena influence the context-dependent problems such as ellipses, anaphoras, pro-forms and referent-transfers. In this paper, we propose a context processing mechanism which fits for the disarranged phenomena, and describe the linguistic knowledge, called &amp;quot;local cohesive knowledge&amp;quot;, which is a constraint for grasping the contextual relationship.</Paragraph>
    <Paragraph position="1"> In Section 2 we will give examples which arc dependent on the context and then describe the cause of difficulty in processing them. In Section 3 we propose &amp;quot;local cohesive knowledge&amp;quot; and apply the mechanism in a dialogue-machine translation system in Section 4.</Paragraph>
