A hybrid video recommendation system based on a graph-based algorithm

Öztürk, Gizem
This thesis proposes the design, development and evaluation of a hybrid video recommendation system. The proposed hybrid video recommendation system is based on a graph algorithm called Adsorption. Adsorption is a collaborative filtering algorithm in which relations between users are used to make recommendations. Adsorption is used to generate the base recommendation list. In order to overcome the problems that occur in pure collaborative system, content based filtering is injected. Content based filtering uses the idea of suggesting similar items that matches user preferences. In order to use content based filtering, first, the base recommendation list is updated by removing weak recommendations. Following this, item similarities of the remaining list are calculated and new items are inserted to form the final recommendations. Thus, collaborative recommendations are empowered considering item similarities. Therefore, the developed hybrid system combines both collaborative and content based approaches to produce more effective suggestions.


Visual composition component oriented development
Öztürk, Murat Mutlu; Doğru, Ali Hikmet; Department of Computer Engineering (2005)
This thesis introduces a visual composition approach for JavaBeans components, in compliance with the Component Oriented Software Engineering (COSE) process. The graphical modeling tool, COSECASE, is enhanced with the ability to build a system by integrating domain-specific components. Such integration is implemented by defining connection points and interaction details between components. The event model of the JavaBeans architecture is also added to the capabilities.
A Feedback Quantization Scheme Leveraging Fairness and Throughput for Heterogeneous Multi-User Diversity Systems
SOYDAN, Yusuf; Candan, Çağatay (Institute of Electrical and Electronics Engineers (IEEE), 2010-06-01)
We propose a feedback quantization scheme for downlink multiuser diversity systems. The scheme is designed for heterogeneous users, i.e., users operating under different levels of mean signal-to-noise ratios (SNRs). The proposed scheme equally distributes the channel access time to user clusters and, at the same time, maximizes the sum-rate capacity under equal-channel-access-time constraint. The method is compared to a normalized SNR scheduler, full-feedback scheduler, and finite-rate feedback scheduler wi...
An Approach to manage variability in object-oriented applications with feature models
Bulut, Ender; Şener, Cevat; Department of Computer Engineering (2014)
In this thesis, an approach to manage variability in object-oriented applications by using a feature modeling language and a simple source code generation technique has been designed and developed. This approach provides developing configurable object oriented applications in a practical way. That is, an application developed with our approach takes just a configuration file including user selections in a pre-defined domain as input and then automatically configure and manage itself with respect to these se...
A business rule approach to requirements traceability
Narmanlı, Murat; Doğru, Ali Hikmet; Department of Computer Engineering (2010)
In this thesis, a requirements traceability model is proposed in order to make efficient and effective change request impact analysis. The proposed model is a requirements – requirements traceability model. There are several researches regarding software requirements traceability problem. The main problem of these researches is that the proposed solutions can not be applied to software industry with affordable changes. However, current literature begins to see that describing all the software requirements i...
Deploying and invoking secure web services over JXTA framework
Görgün, İlhami; Doğaç, Asuman; Department of Computer Engineering (2004)
Web services introduce a new paradigm for distributed computing, and the technology that it introduces constructs a new type of Web application. Web services can be described as any software that makes its discovery and invocation available over the Internet, and uses a standardized XML messaging system. The term peer-to-peer refers to a class of decentralized systems enabling the access of shared resources available on peers that are acting both as client and as server. In this work, a peer-to-peer approac...
