13. The user-interactive automatic translation method for a mobile device of claim 9 , wherein said generating the translation includes: recognizing the error-corrected text string sentence by sentence; analyzing and tagging source language morphemes of the sentence-by-sentence recognized text string based on first automatic translation information stored in the automatic translation information DB to restore each of vocabularies included in the text string into original form thereof; analyzing a grammatical correlation and a modification structure of vocabularies included in each sentence of the recovered text string based on second automatic translation information stored in the automatic translation information DB; performing a source language-to-target language conversion on the analyzed text string based on third automatic translation information stored in the automatic translation information DB to convert vocabularies of source language to vocabularies of target language; and applying a grammar of target language to the structure-converted and vocabulary-converted text string to generate the translation.
