PURPOSE: An information retrieval system and method is provided to give a word code to a search word according to a rule, to search for the word code in a database, to separate retrieved information into information identical to a word code of a search word, information having a main component word code identical to a main component word code of a search word, and information having a component word code identical to a component word code of a search word, to weight the retrieved information according to a matching value, and to display the retrieved information according to a weighted order. CONSTITUTION: The method comprises steps of determining if an input search word is a compound noun consisting of more than two words(S8100-S8110), in a case that the input search word is a single word, converting the search word into a corresponding word code, searching for information in a database based on the word code, and retrieving information identical to the search word code or information including word codes most similar to the search word code(S8130-S8140), giving a serial number to the retrieved information(S8150), in a case that the input search word is a compound noun, determining if a subject word is separable from the search word(S8120), in a case that the subject word is separable from the search word, converting the search word into a word code, searching for information in a database based on the word code, and retrieving information identical to the search word code or information including word codes most similar to the search word code(S8160), giving a serial number to the retrieved information(S8170), giving a matching value to the retrieved information according as the retrieved information has a word code identical to the search word code, has a main component word code identical to a main component word code of the search word or a component word code identical to a component word code of the search word, determining a weighting order of the retrieved information based on the matching value, in a case that the search word has more than two words and a subject word is separable from the search word, separating the subject word from general words, giving different matching values according as the retrieved information has the subject word or the general word, and determining a weighting order of the retrieved information based on the matching value.
