The term “socialware” is used to indicate systems that try to build a social infrastructure, which is needed to help community activities on the net. Such an infrastructure and systems are needed for establishing forthcoming network communities, which would become the core of social activities through the net. This article describes an outline, experimental instances and further directions of socialware. Our experimental systems reported in this article are: the “Community Organizer” - which aims to support for the formation of new communities, and the “Community Board” - which aims to support for smooth communications between people by visualizing the structure of discussions. We believe that socialware will be a promising application for multiagent systems.
