There is provided a similarity calculation device for calculating an index for judging technical similarity between technical document groups consisting of technical documents. The similarity calculation device includes: technical document group input means (365) for inputting a first technical document group and a second technical group to be compared; technical information input means (371) for inputting technical information; cluster analysis means (380) for searching technical documents contained in the first technical document group and the second technical document group and including the technical information which has been input and decomposing the searched technical documents into a cluster for each technical information; similarity calculation means (380) for calculating the ratio of the total number of clusters obtained as the cluster decomposition against the number of mixed clusters including the technical documents of both of the first technical document group and the second technical document group; and output means (365) for outputting the similarity calculated.
L'invention concerne un dispositif de calcul de similarité permettant de calculer un indice destiné à évaluer une similarité technique entre des groupes de documents techniques composés de documents techniques. Ledit dispositif de calcul de similarité comprend: un organe d'entrée (365) de groupes de documents techniques permettant d'entrer un premier groupe de documents techniques et un second groupe de documents techniques à comparer; un organe d'entrée (371) d'informations techniques permettant d'entrer des informations techniques; un organe d'analyse (380) de grappe permettant de rechercher des documents techniques contenus dans le premier et le second groupe de documents techniques et renfermant les informations techniques qui ont été entrées, et de décomposer les des documents techniques recherchés en une grappe pour chaque information technique; un organe de calcul (380) de similarité permettant de calculer le rapport entre le nombre total de grappes obtenues comme de décomposition de grappe et le nombre de grappes mélangées comprenant les documents techniques du premier et du second groupe de documents techniques; et un organe de sortie (365) permettant d'émettre la similarité calculée en sortie.
