1. A pseudo natural language based human machine dialog device ( 5 ) comprising a computer dialog device having language text represented by one or more semantic-logic-representation devices ( 1 ) and one or more language-presentation devices ( 4 ), wherein, a) said semantic-logic-representation devices ( 1 ) comprising one or more sets of machine codes represented by conceptual objects and/or semantic logics, and whereby at least one said semantic-logic-representation device ( 1 ) is generated for each or set of objects within a conceptual object model in accordance with class hierarchical or object containing relationships; b) said semantic-logic-representation devices ( 1 ) having one conversion function ( 11 ) responsible for converting said semantic-logic-representation device ( 1 ) itself into said one or more language-presentation devices ( 4 ) abiding by different grammar or syntax rules according to a mapping generated on a one-to-one basis for each semantic-logic-representation device ( 1 ) to project into one or more language-presentation devices ( 4 ), said conversion function( 11 ) taking the semantic-logic-representation devices ( 1 ) and language identity as inputs and returns a language-presentation device ( 4 ) searched from the said mapping; c) said semantic-logic-representation devices ( 1 ) having one backwards conversion function( 12 ) responsible for converting of a segment of text corresponding to one or more said language-presentation devices ( 4 ) into said one or more semantic-logic-representation devices ( 1 ) abiding by different grammar or syntax rules and programming requirements according to a generated one-to-one mapping for each language-presentation device ( 4 ) to project into one semantic-logic-representation device ( 1 ), wherein the said conversion function( 12 ) takes said language-presentation device ( 4 ) as input and returns one or more semantic-logic-representation device ( 1 ) searched from the said mapping; d) said language-presentation device ( 4 ) comprising a set of symbols for presentation of a text segment representing a constituent component in a document model with a set of semantic markups embedded to identify a semantic-logic-representation device ( 1 ) and/or other interpreter corresponding to the given segment of text; and e) said pseudo natural language human machine dialog device ( 5 ) presenting said one or more language-presentation devices ( 4 ) to and accepts instructions from end users or third party applications through a set of computer interfaces in carrying out operations on a given segment of text while retaining unchanged integrity and legitimacy of said set of markups embedded, whereby a segment of text is capable of being focused according to input from a user or application based on the said markups embedded, said semantic-logic-representation devices ( 1 ) corresponding to the focused segment of text is located according to said semantic markups embedded and resulting in the associated conversion function ( 12 ) and ( 11 ) capable of being called upon in sequence to generate the content of semantic-logic-representation devices ( 1 ) thereafter resulting in a new version of language-presentation devices ( 4 ) in a different format or language.
