1. A method of storing natural language in a computer and generating further natural language based on the stored natural language by the computer comprising the steps of: preparing a word dictionary which stores language structure information defining individual function of letter series representing words; preparing a configuration dictionary which stores language structure information defining mutual connecting relations of letter series representing particles and symbols; preparing a meaning frame dictionary which stores meaning frames defining abstract meaning structures corresponding to letter series representing words; preparing a meaning analysis grammar which commands mutual case coupling relations and mutual logical coupling relations between words, particles, symbols and the meaning frames corresponding to combinations of the language structure information and further commands insertion of the words, the particles and the symbols into the meaning frames; performing a structure analysis on a natural sentence inputted by making use of the word dictionary and the configuration dictionary; converting the letter series of the inputted natural sentence into a language structure information series; subjecting the inputted natural sentence in the form of the language structure information series to the meaning analysis in such a manner that through application of the meaning analysis grammar to the language structure information series a single or a plurality of meaning frames are read out from the meaning frame dictionary in accordance with commands of the meaning analysis grammar; synthesizing, when a plurality of meaning frames are read out, a meaning frame which defines an abstract meaning expressed by the inputted natural sentence by case coupling and/or logic coupling the meaning frames; and inserting words, particles and symbols into the meaning frames read out or the meaning frame synthesized to thereby determine and produce data sentence correctly expressing the meaning of the inputted natural sentence in the computer, whereby the language structure information series is converted into the data sentence in the form of data structure with a multi layered case-logic language structure.

A method according to claim 1, wherein the data structure includes first data structure and the second data structure, and the first data structure includes at least a first element which stores words, a second element which stores particles, a third element which stores symbols, a fourth element which stores the data commanding prohibition of outputting of the stored word in a natural sentence, a fifth element which stores number of the first data structure in which the same word is to be inserted, a sixth element which stores the data defining the content of the word to be stored, a seventh element which stores the number of the first data structure or the number of the second data structure to be connected by case combination, an eighth element which stores a type of case combination, a ninth element which stores the number of data structure to be connected by logic combination, and a tenth element which stores a type of the logic combination; the second data structure includes at least a eleventh element which stores particles, a twelfth element which stores symbols, a thirteenth element which stores the number of the first data structure connected as Case A (agent case), a fourteenth element which stores the number of data structure MW connected as Case T (time case), a fifteenth element which stores the number of the first data structure connected as Case S (space case), a sixteenth element which stores the number of the first data structure connected as Case O (object case), a seventeenth element which stores number of data structure connected as Case P (predicate case), and an eighteenth element which stores number of the first data structure connected as Case X (auxiliary case).
