Abstract: An intelligent information retrieval program generation system can easily generate an intelligent information retrieval program that is applicable to a wide-area information network such as the Internet. When questions to be used as criteria for determining conclusions, answer alternatives to the questions, and information of conclusions are inputted, a table defining unit defines a conclusion determining table which comprises answer alternatives to each of the questions and conclusions. A knowledge establishing unit displays the conclusion determining table on a display screen, receives inputted answer conditions for the conclusions to be selected, and establishes the answer conditions in the conclusion determining table. A retrieval program generator generates an intelligent information retrieval program for decoding the conclusion determining table in which the knowledge has been established, displaying questions, receiving answers to the questions, and determining conclusions depending on the answers.
