A Semantic Model with Self-Adaptive and Autonomous Relevant Technology for Social Media Applications

Zahra Najafabadi Samani, Alexander Lercher, Nishant Saurabh, Radu Prodan
2019 Zenodo  
To tackle these problems and fulfill the requirements of social media services, there is a need for intelligent mechanisms integrated to the decentralized social media that consider trust in various aspects  ...  However, the lack of central control in the decentralized social network poses new issues of collaborative decision making and trust to this permission-less environment.  ...  This work was accomplished as a part of project "ARTICONF" 1 , funded by the European Union's Horizon 2020 research and innovation program under grant  ...

Logistic Regression Trust–A Trust Model for Internet-of-Things Using Regression Analysis

Feslin Anish Mon Solomon, Godfrey Winster Sathianesan, R. Ramesh
2023 Computer systems science and engineering  
Internet of Things (IoT) is a popular social network in which devices are virtually connected for communicating and sharing information.  ...  But, the interaction is successful only based on the trust that each device has on another. Thus trust is very much essential for a social network.  ...  IoT integrates heterogeneous physical objects into a network to share advanced applications between them. In future, this plays important role in social life.  ...

Integrating Sign Prediction with Behavior Prediction for Signed Heterogeneous Information Networks

Dong Li, Derong Shen, Yue Kou, Tiezheng Nie
2019 IEEE Access  
In order to solve this issue, in this paper, we present a novel model called SPBP to integrate Sign Prediction with Behavior Prediction in the context of signed heterogeneous information networks.  ...  People often use online social networks not only to express attitudes towards others, but also to make decisions, which forms signed heterogeneous information networks.  ...  In [40] a model-based approach for recommendation in social networks is proposed, which employs matrix factorization techniques and uses the mechanism of trust propagation. C.  ...

A Classification of Trust Computation Models for Service-Oriented Internet of Things Systems

Jia Guo, Ing-Ray Chen
2015 2015 IEEE International Conference on Services Computing  
In this paper we classify trust computation models to-date for IoT systems.  ...  To date there is little work on trust computation in IoT environments for security enhancement, especially for dealing with misbehaving owners of IoT devices that provide services to other IoT devices  ...  In this paper we classify state-ofthe-art trust computation models for IoT systems.  ...

Ayush Singhal, Karthik Subbian, Jaideep Srivastava, Tamara G. Kolda, Ali Pinar
2013 arXiv   pre-print
We verify our hypothesis using predictive models for trust reciprocations using features from trade interactions.  ...  In general, we observe that reciprocation rate is inversely related to the barrier level in these networks. We also note that reciprocation has connections across the heterogeneous networks.  ...  Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S.  ...
