International ClassG06F 015/38Foreign Application Priority Data1988-12-13 JPAbstractMeanings of words, phrases, and a sentence are expressed in items. Items, which have equal contents, of a plurality of semantic structures are represented by a common item during the expressing of the meanings. Items, which have different contents, of the semantic structures are written in parallel during the expressing of the meanings. The semantic structures are rewritten into a parallel semantic structure through the representing and the writing. Contents of the parallel semantic structure are examined and corrected in consideration of a parallel characteristic of the parallel semantic structure.Other References
