Web-based collaboration systems typically require dynamic
and context-based interactions between people and services.
To support such complex interaction scenarios, we introduce
a mixed service-oriented system that is composed of both
humans and software services, collaborating and interacting
to perform certain activities. As an example, consider
a professional online help and support community spanning
interactions between human participants and software-based
services. Trust between these members is essential for successful
collaborations and has been extensively studied in
the context of social and collaborative networks. In this paper,
we discuss trust from a collaborative and social point of
view instead of a security perspective. Our approach follows
an interaction monitoring and an interpretative rule-based
trust inference model established on previous behavior.
However, trust relations encourage network members to
continue interacting with successful (and thus trusted) collaboration
partners, and to avoid, or even refuse, interactions
with unknown actors. This behavior has negative sideeffects
from a global community perspective. Given the help
and support environment, a small number of popular network
members will become increasingly overloaded with support
requests. We solve this load and interaction balancing
problem by the means of trustworthy request delegations.
