Explicit and implicit trust modeling compatibility and explicit trust link prediction in trust-based recommendation systems
Demirci, Mehmet Utku; Karagöz, Pınar; Department of Computer Engineering (2022-1-31)
In social networks, trust is a fundamental notion affecting the nature and the strength of ties between individuals. It is also a piece of useful auxiliary information for improving the performance of recommendation systems. The number of ratings given by a user is minimal compared to all items in popular, widely-used e-commerce sites. Therefore, the user-item matrix that is used in collaborative filtering suffers from data sparsity, resulting in poor recommendation quality. Another issue is the cold start ...

Implicit monolithic parallel solution algorithm for seismic analysis of dam-reservoir systems
Özmen, Semih; Kurç, Özgür; Department of Civil Engineering (2016)
This research mainly focuses on developing a computationally scalable and efficient solution algorithm that can handle linear dynamic analysis of dam-reservoir interaction problem. Lagrangian fluid finite elements are utilized and compressibility and viscosity of the fluid are taken into consideration during the reservoir modeling. In order to provide computational scalability and efficiency, domain decomposition methods implemented with parallel computing approaches such as Finite Element Tearing and Inter...
