Title: Context Sensitive Trust Management

Abstract:

The World Wide Web offers to society completely new ways of accessing information and services. Naturally, it also brings new concerns. Trust is one of the phenomena that is becoming a major factor in determining the growth of services such as online transaction and information exchange through the internet. Since people do not have a fair chance to figure out who is behind an e-service, information systems are required to integrate computational models that take care of the trust related issues in a robust way. A trust evaluation process is complicated by two facts: (i) trust is situation-specific, and (ii) trust is person-specific. In this talk, we describe methods that deal with the situation sensitivity of trust and the subjectivity problem.
