Abstract

An analysis engine control device includes: an analysis data selecting for selecting at least two analysis data of a plurality of analysis data that are analysis results obtained by analysis by a plurality of analysis engines, respectively; and an analysis data integration calculating for executing new analysis by using at least two analysis data selected by the analysis data selecting as integration target analysis data. Based on classifications assigned according to one characteristic or each of a plurality of characteristics previously set of the analysis engines, the analysis data selecting selects analysis data obtained by the analysis engines that the classifications are at least partly different from each other, as the integration target analysis data.
