Formalizing and managing activity-aware trust in collaborative environments

Ioanna Dionysiou, David E. Bakken

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Trust is an abstraction of individual beliefs that an entity has for specific situations and interactions. An entity's beliefs are not static but they change as time progresses and new information is processed into knowledge. Trust must evolve in a consistent manner so that it still abstracts the entity's beliefs accurately. In this way, an entity continuously makes informed decisions based on its current beliefs. This chapter presents and discusses a conceptual trust framework that models an entity's trust as a relation whose state gets updated as relevant conditions that affect trust change. The model allows entities to reason about the specification and adaptation of trust that is placed in an entity. An intuitive and practical approach is proposed to manage end-to-end trust assessment for a particular activity, where multiple trust relationships are examined in a bottom-up evaluation manner to derive the overall trust for the activity.
