Generation and Development of Cyber Commons in Digital Society

从社会信息系统的角度讨论了网络公地的产生和发展。网络公地是在电子网络中发展起来的信息和知识的积累空间。我们可以将网络公地与自然公地进行对比。网络公地是一个不同于牧场或自然生长的森林的空间。对自然公地的观察主要集中在对自然公地的利用上，而对网络公地的产生和利用则需要讨论。在信息产品的所有权方面，网络公地必须进一步探索。为了探索网络公地，我们开发了一个生命援助协调系统（LACS），以支持患有疾病的孩子的父母，以及一个信息系统的概念设计，以支持印度尼西亚农民的农产品供应链管理系统。为了探讨信息发布的效果，我们以某地方政府开发的虚拟会议室为例进行了观察。网络公地可以为制定物流战略和制定支持公司外包的虚拟组织提供基础。关于消费者行为，我们开发了一个消费者在线交易的声誉管理系统模型，一个描述信息渠道对模拟赢家通吃现象的影响的模型，以及一个描述通过移动电话交流的各种合作伙伴减少的模型。我们探索了基于操作组织概念的多智能体模拟器的可能性，以及包括社会信息学、协调科学、复杂系统等跨学科方法的可能性，采用了以术语关系为重点的方法。我们将利用这些发现来探索网络公地的特性。

Generation and development of cyber commons are discussed in a perspective of social information systems. A cyber commons is an accumulative space of information and knowledge developed in an electronic network. We can contrast the cyber commons with the natural commons. The cyber commons is a space different from pasture or forest grown naturally. Observations of the natural commons are mainly focused on their utilization, however, the cyber commons has to be discussed its generation as well as its utilization. The cyber commons has to be explored further with respect to the property of information goods.In order to explore the cyber commons, we have developed a life aids coordination system (LACS) to support parents who have a child suffered from illness, and a conceptual design of information system that supports farmers in Indonesia with a supply chain management system of agricultural products. To discuss an effect of information release, we have observed a case of virtual conference room developed by a local government. The cyber commons may provide a basis to develop a logistic strategy and to formulate a virtual organization that supports an out-sourcing of a company. Concerning consumers behavior, we have developed a model of reputation management system for an on-line transaction among consumers, a model describing an effect of information channels to simulate winner-takes-all phenomena, and a model that describes decreases in variety of partners in communications by mobile phone.We have explored possibilities of multi-agent simulator based on a concept of operational organization, and possibilities of interdisciplinary approach including social informatics, coordination science, complex systems, and so on, employing a method focused on terms relations.We are to explore the properties of cyber commons employing these findings.
