1. A data cooperation system in which a first system, a second system, and a third system are connected to a network to execute cooperation of information, wherein
the first system includes a first computer providing an already operating service, collects data generated in the first system, to execute a predetermined service, and collects and publicizes data used for the service as behavior data,
the second system includes a second computer acquiring the behavior data publicized by the first system and executing verification process of a case where the behavior data is applied to a new fourth system,
the verification process includes excluding data out of range of current rules of the first system from the behavior data, generating learning data and environmental data related to a learning target based on the behavior data where the data out of range of current rules of the first system is excluded, generating a virtual model from the learning data, and inputting the environmental data to the model to generate a verification result as verification data, and publicizes the verification data,
the third system includes a third computer receiving the behavior data publicized by the first system and the verification data publicized by the second system to support decision of determination result data, generates, and publicizes the determination result data including a determination result and an improvement rule based on the verification data publicized by the second system and the current rules of the first system,
the second system executes the verification process again based on the improvement rule instead of the current rules when the publicized determination result indicates that application of the fourth system to the first system is negated, and
the first system applies the improvement rule to the first system when the determination result indicates that application of the fourth system to the first system is permitted.
