METHOD FOR CONVERTING COMPOSITE SENTENCE INCLUDING NATURAL LANGUAGE AND MATHEMATICAL FORMULA INTO LOGICAL EXPRESSION, APPARATUS AND COMPUTER-READABLE RECORDING MEDIUM WITH PROGRAM THEREFOR

摘要

PURPOSE: A method for converting a composite sentence including natural languages and mathematical formulas into logical expression, a device for the same, and a computer-readable recording medium for the same are provided to generate a rule required for searching mathematical questions based on natural language tokens. CONSTITUTION: An information inputting part(110) receives a composite sentence including natural languages and mathematical formulas. A sentence analyzing part(120) analyzes the structure of the composite sentence. The sentence analyzing part generates a mathematical formula token and a natural language token with respect to mathematical formula data and the natural languages. An action extracting part(130) extracts action information corresponding to the meaning of the natural language token. An action implementing part(140) structures the extracted action information to the mathematic formula token.
