Enhancing the trust-based recommendation process with explicit distrust

Patricia Victor, Nele Verbiest, Chris Cornelis, Martine De Cock
2013 ACM Transactions on the Web  
In this article, we introduce a distrust-enhanced recommendation algorithm which has its roots in Golbeck's trust-based weighted mean.  ...  These are the so-called trust-enhanced recommendation systems.  ...  In this section, however, we explore how distrust may enhance the trust-based recommendation process.  ...

Multi-faceted trust and distrust prediction for recommender systems

Hui Fang, Guibing Guo, Jie Zhang
2015 Decision Support Systems  
Many trust-aware recommender systems have explored the value of explicit trust, which is specified by users with binary values and simply treated as a concept with a single aspect.  ...  The experimental results on real-world data sets demonstrate the effectiveness of our proposed model in further improving the performance of existing state-of-the-art trust-aware recommendation approaches  ...  The newly predicted trust and distrust values can effectively enhance the performance of the existing trust-aware recommender systems.  ...

Context-sensitive Diagnosis of Quality Defects in Object-Oriented Software Systems

Jörg Rech
2009 Künstliche Intelligenz  
The central idea of the approach described in the thesis consists in exploiting information from social trust networks in order to to enhance document recommendations and document rankings.  ...  The recent success of social networks such as Friendster or Facebook with their millions of users led to the question on whether recommender systems can benefit from this data.  ...  A trust-based recommender system would advise against a forged article if its author is distrusted.  ...
