    <pub:abstract><![CDATA[The growth in knowledge sharing enabled by the (Semantic) Web has made trust an increasingly critical issue.
Based on explicit inter-agent trust relations, a trust network
emerges on the (Semantic) Web in the knowledge sharing
context. The concept of a trust network and its application
to knowledge sharing have received recent attention but neither their structural properties (e.g. dynamics, complexity)
nor inference mechanisms (e.g. trust discovery, trust evolution, trust propagation) have been well addressed. This
paper formalizes trust network inference notions, providing both data and computational models, and suggests an
evaluation model for benchmarking. The data model clari-
ﬁes the data (context, restriction, output) used by trust network inference for knowledge sharing. It also elaborates
trust network representation and articulates different types
of trust. The computational model reviews graph theory
and referral network interpretations of trust network inference and proposes a new one that treats trust network as
an emergent property. This new model supports both trust
evolution and trust propagation. The evaluation model describes metrics as well as methods to generate test scenarios and data. We argue that this approach is more customizable, ﬂexible and scalable than traditional approaches such
as public reputation systems and collaborative ﬁltering.]]></pub:abstract>
