Cyber-human social co-operating system: Application design and implementation

Reducing wealth inequality and resource waste is a global challenge. A fundamental problem within the capitalist economy, put simply, lies in the enslavement of labor and the colonization of resources. To address these issues, movements promoting digital democracy and cooperative platforms have emerged as viable alternatives to traditional capitalist systems. From the perspective of integrating information systems with real-world social, environmental, and economic systems, Cyber-Physical Systems have been proposed for applications in Industry 5.0 and Society 5.0. One such CPS is the Social Co-OS (cyber-human social co-operating system). Social Co-OS is a co-operating system between cyber and human societies that conceptualizes the social system as a dynamic, circular structure composed of three layers: individual behavior, interindividual interaction, and institutional formation. Within this framework, the cyber system supports collective decision-making and individual cooperative behavior across these layers. The objective of this study is to define a novel application architecture based on the Social Co-OS concept, design a user interface flow, and implement it in practice. Specifically, we develop a social impact evaluator, a pluralistic policy simulator, and a consensus-building facilitator, which constitute the deliberative and political loop of Social Co-OS. Additionally, we implement a personality estimator and a behavior change promoter, which constitute the operational and administrative loop, along with a common mediator that serves as the cyber-human interface. Through these implementations, we demonstrate that Social Co-OS applications can effectively support human social systems and offer practical utility for policy co-making and co-operation, as evidenced by examples grounded in real-world challenges.

Composite Consensus-Building Process: Permissible Meeting Analysis and Compromise Choice Exploration

In solving today's social issues, it is necessary to determine solutions that are acceptable to all stakeholders and collaborate to apply them. The conventional technology of "permissive meeting analysis" derives a consensusable choice that falls within everyone's permissible range through mathematical analyses; however, it tends to be biased toward the majority in a group, making it difficult to reach a consensus when a conflict arises. To support consensus building (defined here as an acceptable compromise that not everyone rejects), we developed a composite consensus-building process. The developed process addresses this issue by combining permissible meeting analysis with a new "compromise choice-exploration" technology, which presents a consensusable choice that emphasizes fairness and equality among everyone when permissible meeting analysis fails to do so. When both permissible meeting analysis and compromise choice exploration do not arrive at a consensus, a facility is provided to create a sublated choice among those provided by them. The trial experimental results confirmed that permissive meeting analysis and compromise choice exploration are sufficiently useful for deriving consensusable choices. Furthermore, we found that compromise choice exploration is characterized by its ability to derive choices that control the balance between compromise and fairness. Our proposed composite consensus-building approach could be applied in a wide range of situations, from local issues in municipalities and communities to international issues such as environmental protection and human rights issues. It could also aid in developing digital democracy and platform cooperativism.

Social Co-OS: Cyber-Human Social Co-Operating System

The novel concept of a Cyber-Human Social System (CHSS) and a diverse and pluralistic 'mixed-life society' is proposed, wherein cyber and human societies commit to each other. This concept enhances the Cyber-Physical System (CPS), which is associated with the current Society 5.0, a social vision realised through the fusion of cyber (virtual) and physical (real) spaces following information society (Society 4.0 and Industry 4.0). Moreover, the CHSS enhances the Human-CPS, the Human-in-the-Loop CPS (HiLCPS), and the Cyber-Human System by intervening in individual behaviour pro-socially and supporting consensus building. As a form of architecture that embodies the CHSS concept, the Cyber-Human Social Co-Operating System (Social Co-OS) that combines cyber and human societies is shown. In this architecture, the cyber and human systems cooperate through the fast loop (operation and administration) and slow loop (consensus and politics). Furthermore, the technical content and current implementation of the basic functions of the Social Co-OS are described. These functions consist of individual behavioural diagnostics, interventions in the fast loop, group decision diagnostics and consensus building in the slow loop. Subsequently, this system will contribute to mutual aid communities and platform cooperatives.

Positionality-Weighted Aggregation Methods for Cumulative Voting

Respecting minority opinions is vital in solving social problems. However, minority opinions are often ignored in general majority rules. To build consensus on pluralistic values and make social choices that consider minority opinions, we propose aggregation methods that give weighting to the minority's positionality on cardinal cumulative voting. Based on quadratic and linear voting, we formulated three weighted aggregation methods that differ in the ratio of votes to cumulative points and the weighting of the minority to all members, and assuming that the distributions of votes follow normal distributions, we calculated the frequency distributions of the aggregation results. We found that minority opinions are more likely to be reflected proportionately to the average of the distribution in two of the above three methods. This implies that Sen and Gotoh's idea of considering the social position of unfortunate people on ordinal ranking in the welfare economics, was illustrated by weighting the minority's positionality on cardinal voting. In addition, it is possible to visualize the number and positionality of the minority from the analysis of the aggregation results. These results will be useful to promote mutual understanding between the majority and minority by interactively visualizing the contents of the proposed aggregation methods in the consensus-building process. With the further development of information technology, the consensus building based on big data will be necessary. We recommend the use of our proposed aggregation methods to make social choices for pluralistic values such as social, environmental, and economic.
