Abstract: An ecosystem analysis method in which a plurality of users participate and service is provided among the users via a token, includes: obtaining a token transaction history expressing a transaction history of the token of the user and a user activity history expressing an activity history in the ecosystem of the user by a computer; calculating a loyalty index expressing a loyalty level of the user for the ecosystem on the basis of the token transaction history and the user activity history by the computer; and estimating loyalty level in the entire ecosystem by adding up the loyalty indexes of the plurality of users participating in the ecosystem.

Abstract: An object of the present invention is to enable compliance with a data protection policy defined in a data source when a data processing process is performed in cooperation with plural autonomous distributed organizations. In a data management system, a peer node as a terminal executes a data storage process in which the necessity of protection of data obtained from a predetermined data source is determined on the basis of a data protection policy provided from the data source, and in the case where it is determined that the data requires protection, a reference address of the data is stored into a trust data storage area through a cooperation process among the terminals, and correspondence information between the reference address and the data is stored into a non-trust data storage area without performing the cooperation process.

Abstract: Aspects relate to contribution management for quantifying the contribution of solution owners to digital ecosystems based on the growth progress of the digital ecosystem. A contribution management device for managing a contribution of a solution owner in a digital ecosystem, including a data collection unit to collect a first set of solution performance metrics for a first digital solution and a set of ecosystem key performance indicators, a contribution measurement unit to calculate a first contribution score for the first digital solution, and a suggestion unit to generate a set of recommended actions for increasing growth of the digital ecosystem. The contribution measurement unit further includes a growth assessment unit to generate a set of growth progress data for the digital ecosystem and a dynamic weight calculation unit to calculate the first set of metric weights.

Abstract: Described is a means for switching a plurality of different data processing methods or means for changing the type of sensor data to be collected is required. A management computer includes a control unit which stores, in a memory, monitoring means for monitoring a plurality of operation processes to be monitored and management means connected to a network to manage management information about a plurality of different types of external devices for processing a plurality of types of sensor information via the network, the control unit executing the monitoring means and management means in a CPU, in which the control unit determines whether the plurality of operation processes to be monitored is changed, and instructs, when determining that the operation processes are changed, the plurality of different types of external devices to change the processing of the sensor information required to execute the operation processes before changing.
