Development of Encyclopedia of Social Informatics in the Web

从社会信息系统的角度探讨了网络社会信息学百科全书的发展。一个可行的社会信息学百科全书的原型系统已经开发出来，并且百科全书系统使用邮件列表来积累发布到系统中的材料。这本百科全书一定是网络公地的一个典型例子。为了进一步发展，我们概念化了一个社会信息学建模平台，并提出了一个将多智能体仿真与数字图书馆相结合的平台——社会信息学平台。该平台将能够支持对社交网络和人工社会感兴趣的研究人员。我们还开发了一个可视化系统，以支持向百科全书发布信息和知识。该可视化系统基于段落中句子中的术语的关系，对有关社会信息学的新兴文献对显示中的术语进行可视化。我们利用模型和模拟来探索新兴的社会现象。以需求链管理系统为模型，模拟了从客户需求到供应商的信息流。我们发现，管理系统作为一个信息网络，通过在供应商和顾客之间的中介来提高顾客满意度是有希望的。我们研究了移动通信的属性，与学生之间交换信息的各种人相比，通过个人电脑与电话和电子邮件进行比较，并发现移动通信的一个属性，即移动通信可能不会增加与个人电脑电子邮件相比的人的多样性，尽管增加了按摩交流的机会。赢家通吃现象被表述为一个模型，模拟了商品选择的集中趋势，并发现信息渠道数量的增加可能会扩散集中趋势。

Development of encyclopedia of social informatics in the Web is discussed in a perspective of social information systems. A prototype system of viable encyclopedia of social informatics has developed, and the encyclopedia system accumulates material that is posted to the system employing mailing list. This encyclopedia must be a typical example of cyber commons. For the further developments, we conceptualize a modeling platform for the social informatics, and propose Socio-Informatica that is a platform in to integrate multi-agent simulation with digital library. The platform will be able to support researchers who are interested in social network and artificial society.We also develop a visualization system to support posting information and knowledge to the encyclopedia. The visualization system visualizes the terms in the display based on relations of terms in sentences of a paragraph with respect to emerging literatures concerning social informatics.We explore emerging social phenomena employing models and simulations. A demand chain management system is formulated as a model, and simulated information flow with respect to customer demand to venders. We find that the management system may be promising as an information network to improve customer satisfaction intermediated by a mediator between venders and customers. We examine properties of mobile communication with respect to variety of persons who exchange messages among students in comparison that with telephone and with e-mail by personal computer, and find a property of mobile communication that the mobile communication may not increase variety of the persons as contrasted with e-mail by personal computer in spite of increase in opportunity of massage exchanges. Winner-take-all phenomena are formulated as a model, simulated a tendency of concentration in choices of goods, and find that increases in the numbers of information channels may proliferate the tendency of concentration.
