1 Introduction
</SectionTitle>
    <Paragraph position="0"> Due to Internet grow, the number of available documents grows dramatically. There is a strategic need for companies to produce and manage information written in more than 30 languages (HP, IBM, MS, Caterpillar). This requires powerful tools to manage multilingual documents.</Paragraph>
    <Paragraph position="1"> Current techniques for handling multilingual documents use large-grained linking (at the level of HTML pages), but don't allow fine-grained synchronization (at paragraph or sentence level) and don't permit bilingual or multilingual editing through the Web.</Paragraph>
    <Paragraph position="2"> The interest to synchronize at least at the level of sentences is double: ss make it possible to use Machine Aided Human Translation (MAHT) techniques, in particular translation memories, for translating and postediting multilingual documents.</Paragraph>
    <Paragraph position="3"> ss add UNL tags at sentence level to store the translations as well as UNL hypergraphs (anglosemantic interlingual representations), from which raw (or rough!) translations into other languages can be obtained from distant &amp;quot;deconversion&amp;quot; servers.</Paragraph>
    <Paragraph position="4"> Here, we are not concerned with the problem of aligning parallel monolingual documents, or realigning them after they have been modified, a frequent need in the case of leaflets and booklets. (Assimi,2000) proposed a tool to handle the noncentralized management of the evolution of multilingual parallel documents. We consider the case, frequent in the industry, where documents are managed centrally, even if they are distributed on several sites. What happens in general is that they are aligned at the level of large blocks, with one file per block and language (fileXXX.en.htm, fileXXX.fr.htm etc. for HTML pages).</Paragraph>
    <Paragraph position="5"> What we propose is to align them at the level of sentences, but of course not to have one file per sentence. Rather, if there are N languages, for a given &amp;quot;block&amp;quot; corresponding to some unit of processing (e.g. visualization), we will have either N monolingual sentence-aligned files, or 1 multilingual file. In both cases, sentences or place holders for sentences will be linked to a MPM to manage translation and postedition.</Paragraph>
    <Paragraph position="6"> We began to build PolyphraZ in the context of the TraCorpEx project (Translation of Corpora of Examples). A more recent motivation is to extend the BTEC corpus of CSTAR III (163000 sentences in tourism) to French and Arabic, and to evaluate various Chinese-English MT systems on it.</Paragraph>
    <Paragraph position="7"> We will first present the data we start with, and our goals in more detail. In a second part, we will describe the architecture of PolyphraZ, starting from scenarios of use and types of users. Lastly, we will describe the current status of this work.</Paragraph>
