Abstract

Provided are a system and method for searching information using synonyms. The system including: a synonym storing unit for storing synonyms; a similar Korean alphabet character elements storing unit for storing numbers and Korean alphabet character elements, or a combination of Korean alphabet character elements; a similar Korean alphabet character elements synonym creating unit for automatically creating a plurality of synonyms by combining synonym information and information on the numbers, and Korean alphabet character elements or the combination of Korean alphabet character elements, and providing the created synonyms to a querying unit; the querying unit for searching information stored in a database using synonyms stored in the synonym storing unit and a plurality of synonyms of the keyword automatically created by the similar Korean alphabet character elements synonym creating unit based on the inputted keyword.

Claims

1. A system for searching information using synonyms, comprising:

a synonym storing means for storing synonyms;

a similar Korean alphabet character elements storing means for storing numbers and Korean alphabet character elements, or a combination of Korean alphabet character elements, which have a similar pronunciation or morpheme, or which are confusing in recognizing a computer optical letter;

a similar Korean alphabet character elements synonym creating means for automatically creating a plurality of synonyms by combining synonym information stored in the synonym storing means and information on the numbers, and Korean alphabet character elements or the combination of Korean alphabet character elements stored in the similar Korean alphabet character elements storing means when a keyword is inputted, and providing the created synonyms to a querying means; and

the querying means for searching information stored in a database using synonyms stored in the synonym storing means and a plurality of synonyms of the keyword automatically created by the similar Korean alphabet character elements synonym creating means based on the inputted keyword.

2. The system of claim 1, further comprising:

a similar English alphabet/number character elements storing means for storing numbers and English alphabets, or a combination of English alphabets, which have a similar pronunciation or morpheme, or which are confusing in recognizing a computer optical letter; and

a similar English alphabet/number synonym creating means for automatically creating a plurality of synonyms by combining synonym information stored in the synonym storing means and information on the numbers, Korean alphabet character elements or the combination of Korean alphabet character elements stored in the similar Korean alphabet character elements storing means, and information on English alphabets/numbers and a combination of English alphabets/numbers stored in the similar English alphabet/number character elements storing means when a keyword is inputted, and providing the created synonyms to a querying means.

3. The system of claim 1, wherein the synonym means a word having the same meaning, and includes assonant, homophone, heterography, and homography, which are formed of character elements and letters having a similar or same pronunciation or morpheme, and numbers, character elements and combination of character elements, which are confusing in recognizing a computer optical letter.

4. A method for searching information including a database, comprising the steps of:

a) automatically creating a plurality of synonyms by combining synonym information stored in a synonym storing means and information on the numbers, and Korean alphabet character elements or the combination of Korean alphabet character elements stored in the similar Korean alphabet character elements storing means when a keyword is inputted, and providing the created synonyms to a querying means; and

b) searching information stored in a database using synonyms stored in the synonym storing means and a plurality of synonyms of the keyword automatically created by a similar Korean alphabet character elements synonym creating means based on the inputted keyword.

5. The method of claim 4, further comprising the steps of:

c) automatically creating a plurality of synonyms by combining synonym information stored in the synonym storing means and information on the numbers, Korean alphabet character elements or the combination of Korean alphabet character elements stored in the similar Korean alphabet character elements storing means, and information on English alphabets/numbers and a combination of English alphabets/numbers stored in the similar English alphabet/number character elements storing means when a keyword is inputted; and

d) searching information stored in a database using synonyms stored in the synonym storing means of the step b), a plurality of synonyms of a keyword automatically created by the similar Korean alphabet character elements synonym creating means, and synonyms created in the step c).

6. The method of claim 4, wherein a synonym means a word having the same meaning, and includes assonant, homophone, heterography, and homography, which are formed of character elements and letters having a similar or same pronunciation or morpheme, and numbers, character elements and combination of character elements, which are confusing in recognizing a computer optical letter.
