Abstract
A document processing apparatus uses a synonym dictionary to substitute words and phtrases in a document by other synonymous words and phrases. At this juncture, the frequency of use of the words in a document is counted, and the words which have more frequency of use are made the objects of the substitution. Also, the words having more frequency of use are removed from the substitutional candidates or its priority as the candidate is lowered. When counting the frequency of use, a word which constitutes an idiom is counted as an idiom. Also, a proper noun or other words and phrases which cannot be substituted are excluded from the object of counting.
