Semantic Web Recommender Systems [chapter]

Cai-Nicolas Ziegler
2004 Lecture Notes in Computer Science  
Research on recommender systems has primarily addressed centralized scenarios and largely ignored open, decentralized systems where remote information distribution prevails.  ...  Hence, our primary objective targets succesful deployment and leverage of recommender system facilities for Semantic Web applications, making use of novel technologies and conceptions and integrating them  ...  However, our approach requires metrics that compute nearest trustneighbors, and not evaluate trust values for any two given agents.  ...

Enabling reputation interoperability through semantic technologies

Rehab Alnemr, Adrian Paschke, Christoph Meinel
2010 Proceedings of the 6th International Conference on Semantic Systems - I-SEMANTICS '10  
We also show some applications and how this ontologybased reputation model can be applied in a rule-based open reputation system.  ...  Representing it as a simple form of property-rating or a vector of ratings strips it from its original notion and postulation.  ...  INTRODUCTION In an open world of services and collaborations, trust management approaches are used to construct trust relationships between unrelated parties.  ...

Ontological user profiling in recommender systems

Stuart E. Middleton, Nigel R. Shadbolt, David C. De Roure
2004 ACM Transactions on Information Systems  
Two small-scale experiments, with 24 subjects over 3 months, and a large-scale experiment, with 260 subjects over an academic year, are conducted to evaluate different aspects of our approach.  ...  Our two experimental systems, Quickstep and Foxtrot, create user profiles from unobtrusively monitored behaviour and relevance feedback, representing the profiles in terms of a research paper topic ontology  ...  Ontological relationships between topics of interest are used to infer other topics of interest, which might not have been browsed explicitly; an instance of an interest value for a specific class adds  ...

A Review on Computational Trust Models for Multi-agent Systems

Gehao Lu, Joan Lu, Shaowen Yao, Jim Yip
2009 The Open Information Science Journal  
Also the paper proposes an idea of using ontology and XML technologies such as RDF that allow systems to provide both human and machine readable annotations for trust models.  ...  Trust plays important roles on effective interaction and cooperation for multi-agent systems(MAS).  ...  It is necessary to create an ontology built upon XML and RDF that allows systems to provide machine-readable semantic annotations for trust of specific domain. The solution is briefly depicted in Fig.  ...

Towards an Ontology of Trust for Situational Understanding [chapter]

Owain Carpanini, Federico Cerutti
2017 Advances in Intelligent Systems and Computing  
Often trust in the source of information serves as a proxy for evaluating the quality of the information itself, especially in the cases of information overhead.  ...  In this paper we propose a computational methodology for assessing the impact of trust associated to sources of information in situational understanding activities-i.e. relating relevant information and  ...  As part of future work we plan to evaluate techniques for automatic evaluation of trust: we will investigate how topic modelling-i.e. automatically identifying relevant topics in a written document, for  ...

A Study of Recommender System Techniques

Reena Pagare, Anita Shinde
2012 International Journal of Computer Applications  
Recommender systems provide an important response to the information overload problem as it presents users more practical and personalized information services.  ...  These reviews are given by other clients and specialists. User-given reviews are becoming more prevalent.  ...  From the trust network, we can predict what ratings the particular user would give for items.  ...

An Enhanced Semantic Layer for Hybrid Recommender Systems

Iván Cantador, Pablo Castells, Alejandro Bellogín
2011 International Journal on Semantic Web and Information Systems (IJSWIS)  
As a proof of concept and evaluation testbed, the approach is evaluated through its implementation in a news recommender system, in which it is tested with real users.  ...  We propose a three-fold knowledge representation, in which an explicit, semantic-rich domain knowledge space is incorporated between user and item spaces.  ...  On the other hand, the system integrates specific facilities for manual user profile building, such as an ontology browser, and an ontology concept search engine for instant ontology class and instance  ...
