Base Claim:
1. A method for providing a user with a predetermined search result list by a search engine, comprising: maintaining a content information database storing at least one content and registration date information for the content; maintaining a timer, the timer maintaining time information and a time function table, the time function table storing a predetermined time function having time difference information as a variable, wherein the time difference information is difference between the registration date information for the content and the time information; receiving at least one keyword from a user terminal with a search request; searching for at least one content including the at least one keyword using the content information database; computing accuracy of the searched content with respect to the at least one keyword, based on a predetermined accuracy computing criterion; searching for the registration date information for the searched content using the content information database; computing time difference information by using the searched registration date information and the time information received from the timer; computing a time function value corresponding to the computed time difference information by using the time function table; computing importance information of the searched content using the computed accuracy and the computed time function value; sorting at least one content in accordance with the computed importance information, thereby processing the sorted content into search result list information; maintaining a temporal adverb keyword database storing at least one predetermined temporal adverb keyword; wherein computing importance information with respect to the searched content using the computed accuracy and the computed time function value comprises: abstracting at least one temporal adverb keyword stored in the temporal adverb keyword database, from the searched content; and in case that the temporal adverb keyword is abstracted from the searched content, multiplying predetermined weight corresponding to the abstracted temporal adverb keyword to the computed importance information.
