Taxonomy of Computational Trust Models - Abstract 
Lea Viljanen

Trust is defined in a multitude of ways in the research
community. This, in turn, has caused a multitude of formal or
computational trust models to emerge to enable trust use and
dependence in applications. Since the field is so diverse, there also
exists a confusion of terminology, where similar concepts have
different names and, what is more disturbing, also same terms are used
for different concepts.

To organize the research models in a more structured way, this paper
surveys and classifies twelwe computational trust models by three main
aspects: trust calculation input factors, trust clause processing and
output type. Additionally, a common vocabulary for different models is
developed to facilitate cross-model discussions.
