4. Conclusion
</SectionTitle>
    <Paragraph position="0"> We have shown how a parsing method using global information as well as information about the current word, is very effective for increasing the efficiency in the face of natural language phenomena such as categorial and syntactic alternatives.</Paragraph>
    <Paragraph position="1"> This is especially significant in a real-time translation system using large-size dictionaries and realistic grammars for natural language. In such a system, enormous numbers of ride applications, which are caused by categorial and syntactic alternatives and which  evevtually lead to failure, can be rejected or put off by the linear search of an input sentence.</Paragraph>
    <Paragraph position="2"> In this paper, we have focussed on the parsing of English, but this method is also ve~ T effective for Japanese, inasmuch as it has similar features to English. For example, a Japanese sentence also requires a verb, a noun phrase requires a noun, etc, and many structttres involve discontinuities such as &amp;quot;shika -- nai&amp;quot;, &amp;quot;kara ..... made&amp;quot;, &amp;quot;to --- to --- to&amp;quot;, etc.</Paragraph>
    <Paragraph position="3"> In our system, look-ahead conditions are written manually. A compiler which can automatically attach look-ahead conditions at source ATN is being considered for a future system.</Paragraph>
    <Paragraph position="4"> The look-ahead parsing also works very effectively for scientific and technical documents since these docuntents are more complicated and longer than communication dialogues (see 3.2)\[Nogami 1987\].</Paragraph>
