<section anchor="sec-Introduction" title="Introduction">

<t>The iTrust conferences on Trust Management 
  <xref target='ref-lncs2692' /> <xref target='ref-lncs2995' />
  have been convened to bring together contributions from researchers 
  into Trust coming from a variety of disciplines, including computing, 
  economics, law, sociology, philosophy.  
  This note is a survey of papers from the first two such conferences, 
  which attempts to identify and draw out the multidisplinary aspect 
  of the contributions.
  </t>

<t>Paper summaries and topic categorizations are highly personal 
  and subjective.

  Each paper is assigned an identifier of the form lncsnnnn_pp_pp,
  which is derived from its appearance in the Springer LNCS publication 
  series:
  <list style='hanging'>
    <t hangText='nnnn'>is the LNCS volume number

<t>
Proposes a model and algorithm for a distributed reputation system based 
on a formalized model of trust.
</t>
<t>
The system model consists of a number of agents that act as proxies for users 
of the reputation system.  These agents may form network neighborhoods that
pool information about a given trust category.  The trust categories themselves
may be relates by a graph which allows for one category of trust having
impact on another.
</t>
<t>
Each agent's trust in another agent is modelled as a scalar trust value (0..1), 
with no experience being treated as no trust, 
and a confidence vector containing information about the experiences on which 
the trust is based, and a blacklist flag that is set to indicate that 
recommendations from the corresponding agent are to be disregarded.
</t>
<t>
Each agent tracks its own list of recommendations, and also those
recommendations received from other agents, providing a basis for
evaluating (hypertext-like) a 'hub' and 'authority' rating for each agent.
</t>
<t>
A recommendation consists of: 
the identity of that being rated (including its category), 
a rating value (which is an arbitrary simple or complex value),
the identity of the recommender, and
a rating confidence value.
