Abstract
There are provided a storage device and a computer-readable medium capable of efficiently storing keywords contained in description information and efficiently retrieving the keyword. A list producing portion (6) extracts the keywords from the description information and produces a keyword list correlating the keywords with the scene information containing the keywords. A description information converter (8) converts the keywords contained in the keyword list received from the list producing portion (6) among the keywords contained in the externally received description information into reference information for specifying the keywords in the keyword list received from the list producing portion (6). A storage (10) stores the converted description information provided from the description information converter (8) and the keyword list provided from the list producing portion (6).
