<p>PROBLEM TO BE SOLVED: To perform a data mining by suitable handling a semantic relation between words to be dynamically changed corresponding to a retrieval word group. SOLUTION: A data mining device is provided with an orthonormal space generating part 101 for generating an image space I from meta-data expressing the semantic relation between words, data mapping part 102 for mapping an analytic object item group, in which respective items are defined by definition words, to the image space I, partial space selecting part 103 for selecting the partial space of the image space I on the basis of the retrieval word group, data projecting part 104 for projecting the analytic object item group mapped into the image space I to the partial space, object data sorting part 105 for clustering the analytic object item group projected in the partial space, and cluster analytic part 106 for extracting a knowledge by analyzing the cluster group obtained by clustering.</p> |
