To efficiently and smoothly retrieve service information whose acquisition is requested from a prescribed information group as the object of retrieval without selecting a retrieval method.
An information retrieving device accepts a character string for retrieving service information, and specifies attribute retrieval information corresponding to the attributes of the character string, and specifies and extracts the service information based on the attribute retrieval information, and outputs the extracted service information. After the attribute retrieval information is specified, the information retrieval device specifies at least one preliminary attribute determination/retrieval type different from the already specified attribute determination/retrieval type, and specifies the preliminary attribute retrieval information according to the preliminary attribute determination/retrieval type, and specifies and extracts the preliminary service information based on the specified preliminary attribute retrieval information.
