    <pub:abstract><![CDATA[The Semantic Web enables intelligent agents to ``outsource''
knowledge, extending and enhancing their limited knowledge bases. An
open question is how agents can efficiently and effectively access the
vast knowledge on the inherently open and dynamic Semantic Web. The
problem is not that of {em finding} a source for desired information,
but deciding which among many possibly inconsistent sources is most
reliable.  We propose an approach to agent knowledge outsourcing
inspired by the use trust in human society.  Trust is a type of social
knowledge and encodes evaluations about which agents can be taken as
reliable sources of information or services.  We focus on two
important practical issues: {it learning trust} and {it justifying
trust}.  An agent can learn trust relationships by reasoning about its
direct interactions with other agents and about public or private
reputation information, i.e., the aggregate trust evaluations of other
agents.  We use the term trust justification to describe the process
in which an agent integrates the beliefs of other agents, trust
information, and its own beliefs to update its trust model.  We
describe the results of simulation experiments of the use and
evolution of trust in multi-agent systems.  Our experiments demonstrate
that the use of explicit trust knowledge can significantly improve
knowledge outsourcing performance.  We also describe a collaborative
trust justification technique that focuses on reducing search
complexity, handling inconsistent knowledge, and avoiding error
propagation.]]></pub:abstract>
