Web Service technology is one of the most rapidly developing technologies. Since Web Services are defined by several XML-based standards to overcome platform dependency, they are very eligible to integrate with each other in order to establish new services. This composition enables us to reuse existing services, which results in less cost and time consumption. Currently the main issues with Web Service Composition is to define workflow of the services and maximizing the overall Quality of Service (QoS) of the composed service. Most common elements of QoS are execution cost, execution time, availability, successful execution rate, reliability and throughput. Since the selection of the optimal execution plan that maximizes the composition's overall QoS is NP-hard problem, applying optimization techniques is very popular. In this thesis, we propose an improved Genetic Algorithm to optimize the overall QoS of the composed service.

Automatic quality of service (QOS) evaluation for domain specific web service discovery framework
Aşkaroğlu, Emra; Karagöz, Pınar; Department of Computer Engineering (2011)
Web Service technology is one of the most rapidly developing contemporary technologies. Nowadays, Web Services are being used by a large number of projects and academic studies all over the world. As the use of Web service technology is increasing, it becomes harder to find the most suitable web service which meets the Quality of Service (QoS) as well as functional requirements of the user. In addition, quality of the web services (QoS) that take part in the software system becomes very important. In this t...
Improved Genetic Algorithm based Approach for QoS Aware Web Service Composition
Yilmaz, A. Erdinc; Karagöz, Pınar (2014-07-02)
Use of web services is one of the most rapidly developing technologies. Since web services are defined by XML-based standards to overcome platform dependency, they are very eligible to integrate with each other in order to establish new services. This composition enables us to reuse existing services, which results in less cost and time consumption. One of the recent problems with web service composition is to maximize the overall Quality of Service (QoS) of the composed service. Most common elements of QoS...
Web market analysis : static, dynamic, and content evaluation
Erdal, Feride; Arifoğlu, Ali; Department of Information Systems (2012)
Importance of web services increases as the technology improves and the need for the challenging e-commerce strategies increases. This thesis focuses on web market analysis of web sites by evaluating from the perspectives of static, dynamic and content. Firstly, web site evaluation methods and web analytic tools are introduced. Then evaluation methodology is described from three perspectives. Finally, results obtained from the evaluation of 113 web sites are presented as well as their correlations.
A semantic-based user privacy protection framework for Web services
Tumer, A; Dogac, A; Toroslu, İsmail Hakkı (2005-01-01)
Web service technology is an Internet-based distributed computing paradigm to address interoperability in heterogeneous distributed systems. In this paper, we present a privacy framework for Web services which allows user agents to automatically negotiate with Web services on the amount of personal information to be disclosed on behalf of the user. In developing this framework the following key privacy considerations are taken into account: revealing only the minimal pertinent information about the user, no...
