<p>A group of keywords used as clues for searching an information resource for each broadly defined genre. A dictionary in which the keywords are correlated with each other in relation between abstract and embodiment in each genre is prepared. Referring to the dictionary, an information resource in which the user may be interested is inferred using the action log when the user has accessed a web site and keywords included in the information resource which the user has accessed and presented. A keyword-inferring device specifies an abstracted keyword semantically including a keyword inputted by the user according to the inputted keyword and outputs another keyword which the abstracted keyword semantically includes as an embodied keyword. A suitable keyword for search is inferred from the inputted keyword, and an information resource truly useful to the user is efficiently provided.</p> |
