PROBLEM TO BE SOLVED: To construct a knowledge model systematically as an information expressed in the form which can be easily constructed in a general purpose framework.;SOLUTION: A knowledge model construction system 1 has a factor extracting means 31 for extracting technical information terms in the field as a factor on a knowledge model 21, a relationship extracting means 32 for extracting relationship of the extracted factor, an interrelationship information generating means 33 for generating interrelationship information of the factor by stereotyping the relationship of the factor, inter-factor contribution calculating means 34 for calculating relationship of the extracted factor and contribution indicative of strength of the relationship of the factor based on the generated interrelationship of the factor, and a knowledge model storage means 35 for describing the extracted factor, the relationship of the extracted factor, information of interrelationship of the extracted factor, and the calculated contribution between factors in a predetermined format to store them in the knowledge model 21.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
