of both stereotypes and users, (4) using a combination of user and stereotype reputations to estimate the trustworthiness of artifacts and, (5) selecting sets of artifacts to trust.  ...  Trust is a broad concept which, in many systems, is often reduced to user reputation alone. However, user reputation is just one way to determine trust.  ...  We look at trust assessment using a combination of reputation and provenance.  ...

An Architecture for Justified Assessments of Service Provider Reputation

Nathan Griffiths, Simon Miles
2013 2013 IEEE 10th International Conference on e-Business Engineering  
While factors such as cost and quality might be considered, the assessment of reputation is typically based only on a combination of direct experience and recommendations from third parties, without considering  ...  Existing methods for reputation assessment are limited in terms of the extent to which the full interaction history and context is considered.  ...  Most established trust models, such as ReGreT [18] , FIRE [8] , MDT-R [19] and TRAVOS [20] use a combination of direct experience and third party experiences as the base for assessing trust and reputation  ...

Trust as a Proxy Measure for the Quality of Volunteered Geographic Information in the Case of OpenStreetMap [chapter]

Carsten Keßler, René Theodore Anton de Groot
2013 Lecture Notes in Geoinformation and Cartography  
The results of the comparison between trust assessments and quality measure show significant support for the hypothesis that featurelevel VGI data quality can be assessed using a trust model based on data  ...  provenance.  ...  The statistical analysis thus suggests that provenance-based trust assessments do indeed work as proxies for data quality.  ...
