An interlingua language representation method of claim 11 , wherein both lexicon and grammar constructed in a recursive way following human language's natural formation processes, where said recursive way of construction comprising: a. designing said classification code for prototypical concrete noun of said noun word by assigning taxonomy classification code for concrete whole object and meronomy classification code for concrete part object, b. designing said classification code for instrinsic adjective and attached adjective of said adjective word associated with said concrete noun by assigning classification code for adjective as in a triad of object-property-adjective, c. designing event noun of said noun word as label for simple event representing a single clause or for collective event representing implicitly multiple clauses, d. designing property noun of said noun word as comprising intrinsic property noun naming said intrinsic adjective, attached property noun naming said attached adjective, and event property noun naming event adjective for said event noun, e. designing concept noun of said noun word as denoting a complex combination of existing nouns, including at least one abstract noun and zero or more existing concept nouns, organized in a defining manner recursively, f. designing abstract noun of said noun word as comprising said event noun, said property noun, and said concept noun, g. designing ontological noun of said noun word as comprising space noun, time noun, and ontological noun in general, h. designing said prototypical noun word as comprising said concrete noun, said abstract noun, and said ontological noun, i. designing said classification code for said prototypical verb word as sharing the same classification code with said prototypical clause comprising said verb word, j. designing said classification code for word derived from already designed word by firstly assigning it a virtual code for each kind of derivation, secondly assigning it the same classification code of said already designed word as a secondary code, and thirdly assigning it a feature of its derivation, k. designing said prototypical clause as declarative clause of prototypical argument in active voice with feature sets of time, space, and adverb collected separately, l. designing said classification code for said prototypical clause by assigning a three-level classification code, where: 1. said first-level code comprising classification codes for property and state clauses, relation clause, and dynamic clause, 2. said second-level code being based on syntactic classification, and 3. said third-level code being based on semantic classification, m. designing the one-argument dynamic clause of said prototypical dynamic clause as comprising prototypical clauses of change of property, change of state, and self-action, with the one argument of said prototypical self-action clause as being prototypically agentive, n. designing a non-prototypical clause of said one-argument dynamic clause as its corresponding said prototypical clause having said prototypical agentive argument filled by un-collocated concrete noun or abstract noun, o. designing the two prototypical arguments of the two-argument dynamic clause of said prototypical dynamic clause as having said two arguments labeled S and O respectively, where said S argument is prototypically agentive and said two arguments, together with the comprising verb V, correspond to the {V,S,O} typing of natural languages, and p. designing a non-prototypical clause of said two-argument dynamic clause as its corresponding said prototypical clause having at least one of said two prototypical arguments replaced from collocated noun to un-collocated noun, or from concrete noun to abstract noun.
