5.9 Conclusions
Social web services have the possibility to be an important social infrastructure in
the future. The foundation of trust is indispensable to reduce the risk caused by new
encounters and to provide the freedom to obtain new businesses and new friends for
us over social web services.
The trust infrastructure for social web services based on the reputation of the
people is the most natural trust foundation now. The application area of our trust
mechanism is limited. Nevertheless, our proposal is part of the reconstruction of
social devices for trust which have been considered by the long history of human
beings. We have to learn more from this history.
Technologies used to prevent the phenomenon of information cascading are still
immature. However, there is a lot promising knowledge about approaching these
problems. We expect that we can progress this research and apply it to such
knowledge.
