13. A computer-implemented method for searching and providing information in a system including an information database that stores information contents and a metadata database that stores metadata describing the information contents, the method comprising: detecting an intention of an information searcher by using a result of a syntax analysis of keywords inputted by the information searcher; extracting a plurality of metadata which describe information contents meeting the detected intention of the information searcher from the metadata stored in the metadata database; generating an editor of the information searcher in a table form in which the plurality of metadata extracted from the metadata stored in the metadata database are paired with a plurality of metadata fields of the editor and displaying the generated editor to the information searcher; receiving a plurality of metadata items inputted by the information searcher through the plurality of metadata fields of the editor of the information searcher; determining a search directory for searching contents in the information database according to the detected intention of the information searcher; searching information contents having metadata corresponding to the plurality of metadata items inputted through the plurality of metadata fields of the editor of the information searcher from the information database; comparing the plurality of metadata items inputted through the plurality of metadata fields of the editor of the information searcher with the searched metadata corresponding to the searched information contents; selecting, among the searched information contents, information contents having a degree of coincidence exceeding a pre-defined threshold based on a comparison result; displaying the selected information contents; detecting an intention of an information provider by using a result of the syntax analysis of keywords inputted by the information provider; extracting a plurality of metadata which describe information contents meeting the detected intention of the information provider from the metadata stored in the metadata database; generating an editor of the information provider in a table form in which the plurality of metadata extracted from the metadata stored in the metadata database are paired with a plurality of metadata fields of the editor and displaying the generated editor of the information provider to the information provider; receiving a plurality of metadata items inputted by the information provider through the plurality of metadata fields of the editor of the information provider; determining a store directory for storing information contents in the information database according to the detected intention of the information provider; and storing information contents represented by the plurality of inputted metadata items integrated with the plurality of metadata in the directory of the information database determined according to the intention of the information provider.
13. A computer-implemented method for searching and providing information in a system including an information database that stores information contents and a metadata database that stores metadata describing the information contents, the method comprising: detecting an intention of an information searcher by using a result of a syntax analysis of keywords inputted by the information searcher; extracting a plurality of metadata which describe information contents meeting the detected intention of the information searcher from the metadata stored in the metadata database; generating an editor of the information searcher in a table form in which the plurality of metadata extracted from the metadata stored in the metadata database are paired with a plurality of metadata fields of the editor and displaying the generated editor to the information searcher; receiving a plurality of metadata items inputted by the information searcher through the plurality of metadata fields of the editor of the information searcher; determining a search directory for searching contents in the information database according to the detected intention of the information searcher; searching information contents having metadata corresponding to the plurality of metadata items inputted through the plurality of metadata fields of the editor of the information searcher from the information database; comparing the plurality of metadata items inputted through the plurality of metadata fields of the editor of the information searcher with the searched metadata corresponding to the searched information contents; selecting, among the searched information contents, information contents having a degree of coincidence exceeding a pre-defined threshold based on a comparison result; displaying the selected information contents; detecting an intention of an information provider by using a result of the syntax analysis of keywords inputted by the information provider; extracting a plurality of metadata which describe information contents meeting the detected intention of the information provider from the metadata stored in the metadata database; generating an editor of the information provider in a table form in which the plurality of metadata extracted from the metadata stored in the metadata database are paired with a plurality of metadata fields of the editor and displaying the generated editor of the information provider to the information provider; receiving a plurality of metadata items inputted by the information provider through the plurality of metadata fields of the editor of the information provider; determining a store directory for storing information contents in the information database according to the detected intention of the information provider; and storing information contents represented by the plurality of inputted metadata items integrated with the plurality of metadata in the directory of the information database determined according to the intention of the information provider. 18. The method of claim 13 , further comprising: adding at least one additional service to a result of the searching.
