Abstract

Disclosed is a device for discourse processing that resolves problems dependent on inter-sentential information (such as, pronoun referents, word sense ambiguities, attachment ambiguities, and the scope of some adverbs) by means of a simple framework called a "referential network."

Discourse Processing using Referential Network

      Disclosed is a device for discourse processing that resolves
problems dependent on inter-sentential information (such as, pronoun
referents, word sense ambiguities, attachment ambiguities, and the
scope of some adverbs) by means of a simple framework called a
"referential network."

      Generally, most of the content words in a sentence can be found
in other sentences in the same text.  In computer manuals, over 90%
of all the content words are found more than once, and over 80% of
the content words are found more than four times within the same
manual.  In addition, morphologically identical content words in the
same text are normally used in the same way (with the same word
sense, and modifying similar concepts).

      This device uses this feature in its first step, which is to
make links among morphologically identical words in a text.  This set
of links in a text is named a "referential network."  Through this
referential network, inter-sentential information on the behavior of
morphologically identical words in separate sentences is referred to
and used to resolve context-dependent problems.  Here, the behavior
of a word means the plausibility of each candidate for a specific
word sense and modifiee.

      For example, in the title "Role of an operator," the word
"operator" may be a person who operates a machine or a logical
operator, but there is no sufficient information to resolve this
