SYSTEM AND METHOD FOR RETRIEVING INFORMATION, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To make information retrieval results provided by a retrieval engine to be more appropriate to a retrieval target of an information retriever. SOLUTION: A character enhancement analyzing part 124 acquires an attribute showing enhancement given to a character string included in a web page 20. An index registering part 126 associates logical position information of the web page 20 and an enhancement attribute about a character string being an extraction source of a word with the word extracted from the character string by a character string analyzing part 125 to register them in an index file 310. An information retrieving part 210 acquires position information associated with a word representing a retrieval target. A retrieval result managing part 220 sorts the acquired position information to make a word with an enhancement attribute associated to take precedence with respect to a word made to be an object of retrieval of the position information. An HTML preparing part 410 prepares an HTML file representing the sorted position information and transmits the HTML file to the Internet 4.
