Abstract

The present invention discloses a search engine system with coded information and a search method using the same. The system includes a key word input part, a database for storing information as word codes which are not real standard words, and a central process unit for assigning a word code assigned to a standard word to a word input through the key word input part or a client system, and searching information corresponding to the word code of the input word through the database. In the invention, when key word(s) relating to information to be searched are input through the information input system, the input words are coded and the search is performed using the word codes through the database, thereby searching the information more precisely. In addition, since a plurality of different words having similar or same meanings are coded as one standard word code according to a simple coding rule and stored in the database, the process time for searching the information can be greatly reduced.

to convert into only one word codes out of two and/or more word codes for multiple meaning words, through user'"'"'s choosing one of them after multi-meanings shown on the display, or with the method of selecting one word code through algorithm; and

to search the information with the method of comparing the basic word codes within the converted word code and the basic word codes within the word code of the information which is stored in the word data base;

wherein the database further comprises at least one command word descriptive of and for operating a computer program, and a word code including basic word code representative of the command word, and

wherein, when the coded retrieval word for the retrieval word includes the basic word code corresponding to the at least one command word, the central process unit operates a computer program corresponding to the at least one command word.

6. The method of claim 5 wherein the basic words in the database are of a first language, wherein when the inputted word is of a second language that is different than the first language, the inputted word is coded using at least one basic word code corresponding to the basic word of the first language having the same meaning as a basic word representative of the inputted word that is of the second language.

7. The method of claim 5 wherein main words among words describing the inputted word are coded using the basic word code.

8. The method of claim 5 wherein the basic word codes for the basic words in the database have a fixed number of code digits.

9. The method of claim 5 wherein, the inputted word is coded according to a code arrangement order set as a function of speech of the at least one basic word whose basic word code represents the meaning of inputted word.

10. The method of claim 5 wherein the inputted word is a sentence comprising a plurality of words, a functioning code is assigned to each word of the sentence.

11. The method of claim 5 wherein the inputted word is a sentence.
