METHOD FOR EXTRACTING SEMANTIC DISTANCE OF MATHEMATICAL SENTENCE AND CLASSIFYING MATHEMATICAL SENTENCE BY SEMANTIC DISTANCE, APPARATUS AND COMPUTER-READABLE RECORDING MEDIUM WITH PROGRAM THEREFOR

摘要

PURPOSE: A classifying method of a mathematics sentence, an apparatus for the same, and computer-readable recording medium are provided to obtain similarity of mathematic content which is stored in search of the inputted mathematics sentence by extracting semantic distance. CONSTITUTION: A user query input unit(140) receives a query from a user. A query parsing unit(150) extracts a keyword which is included in the inputted user query. An index information unit(130) indexes a natural token in semantic information and a mathematics token. A semantic distance extracting unit(160) measures semantic distance with semantic information and obtains similarity.
