People working in an office concurrently engage in two or more office
activities, which can be classified into personal and group work. To i
ncrease office productivity with a computer system, both personal and
group work should be supported. However, currently available office wo
rk support systems, such as a workflow management system or a software
secretary, focuses on one or the other of these activities. In this p
aper, an agent-based office system that supports both personal and gro
up work is introduced. In this system, there exist agents for personal
and group work, and they are mutually connected in a two-layered agen
t network to work in cooperation. With the support of these agents, pe
ople in an office can expect to perform both their personal and group
work efficiently.
