1. An analysis engine control device, comprising: an analysis engine meta-information table storing an analysis process content and an analysis process result characteristic for each analysis engine; a process flow generating unit for, in response to an analysis process request in which an analysis process content and an analysis process result condition are set, selecting a plurality of analysis engines each executing an analysis process which satisfies the analysis process result condition set in the analysis process request and corresponds to the analysis process content based on the analysis engine meta-information table, and generating a process flow showing an analysis procedure by the selected analysis engines; and an analysis process executing unit for executing an analysis process by each of the analysis engines based on the generated process flow, wherein the process flow generating unit is configured to, in accordance with a result of an actual analysis process by each of the analysis engines executed by the analysis process executing unit, correct the process flow so that an analysis process satisfying the analysis process result condition and corresponding to the analysis process content is executed, based on the analysis engine meta-information table.
