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 are response time, availability, reliability, throughput and cost (price). Since the selection of the optimal execution plan that maximizes the composition's overall QoS is a NP-hard problem, applying optimization techniques is very popular. In this work, we propose an improved Genetic Algorithm based approach to optimize the overall QoS of the composed service. Experimental results indicate improvement for QoS of the composition built by the proposed methods.

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...
A Genetic algorithm based technique for qos-aware web service composition
Yılmaz, Ahmet Erdinç; Karagöz, Pınar; Department of Computer Engineering (2013)
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 t...
Automated Web Services Composition with the Event Calculus
Aydin, Onur; Çiçekli, Fehime Nihan; Cicekli, Ilyas (2007-10-24)
As the web services proliferate and complicate it is becoming an overwhelming job to manually prepare the web service compositions which describe the communication and integration between web services. This paper analyzes the usage of the Event Calculus, which is one of the logical action-effect definition languages, for the automated preparation and execution of web service compositions. In this context, abductive planning capabilities of the Event Calculus are utilized. It is shown that composite process ...
Query interface and query language for domain specific web service discovery system
Özdil, Hilal; Karagöz, Pınar; Department of Computer Engineering (2011)
As the number of the published web services increase, discovery of the web services with the desired functionality and quality is becoming a challenging process. Selecting the appropriate web services among the ones that o er the same functionality is also a challenging task. The web service repositories like UDDI (Universal Description Discovery and Integration) support only the syntactic searchs. Quality of service parameters for the published web services can not be queried over these repositories. We ha...
Semantic Annotation of Web Services with Lexicon-Based Alignment
Cantürk, Deniz; Karagöz, Pınar (2011-07-04)
As the number of available web services published in registries and on web sites increases, web service discovery becomes a challenging task. One solution to the problem is to use distributed web service search system composed of domain specific sub service discoverers. Using ontology is the most common practice to specify domain knowledge. However, an important problem at this point is the lack of semantic annotation for currently available web services. For this reason, there is a strong need for a mechan...
