  In a consistent text, many words and phrases are repeatedly used in more than
one sentence. When an identical phrase (a set of consecutive words) is repeated
in different sentences, the constituent words of those sentences tend to be
associated in identical modification patterns with identical parts of speech
and identical modifiee-modifier relationships. Thus, when a syntactic parser
cannot parse a sentence as a unified structure, parts of speech and
modifiee-modifier relationships among morphologically identical words in
complete parses of other sentences within the same text provide useful
information for obtaining partial parses of the sentence. In this paper, we
describe a method for completing partial parses by maintaining consistency
among morphologically identical words within the same text as regards their
part of speech and their modifiee-modifier relationship. The experimental
results obtained by using this method with technical documents offer good
prospects for improving the accuracy of sentence analysis in a broad-coverage
natural language processing system such as a machine translation system.
