Some mechanisms to enable an effective transition from domain models to web service descriptions are developed. The introduced domain modeling support provides verification and correction on the customization part. An automated mapping mechanism from the domain model to web service ontologies is also developed. The proposed approach is based on Feature-Oriented Domain Analysis (FODA), Semantic Web technologies and ebXML Business Process Specification Schema (ebBP). Major contributions of this work are the conceptualizations of a feature model for web services and a novel approach for knowledge-based elicitation of domain-specific outcomes in order to allow designing and deploying services better aligned with dynamically changing business goals, stakeholders' concerns and end-users' viewpoints. The main idea behind enabling a knowledge-based approach is to pursue automation and intelligence on reflecting business requirements into service descriptions via model transformations and automated reasoning. The proposed reference variability model encloses the domain-specific knowledge and is formalized by using Web Ontology Language (OWL). Adding formal semantics to feature models allows us to perform automated analysis over them such as the verification of model customizations through exploiting rule-based automated reasoners. This research was motivated due to the needs for achieving productivity gains, maintainability and better alignment of business requirements with technical capabilities in engineering service-oriented applications and systems.

A recommendation system combining context-awarenes and user profiling in mobile environment Ulucan, Serkan; Erkmen, Aydan Müşerref; Department of Electrical and Electronics Engineering (2005) Up to now various recommendation systems have been proposed for web based applications such as e-commerce and information retrieval where a large amount of product or information is available. Basically, the task of the recommendation systems in those applications, for example the e-commerce, is to find and recommend the most relevant items to users/customers. In this domain, the most prominent approaches are أcollaborative filteringؤ and أcontent-based filteringؤ. Sometimes these approaches are called as أ...
User modeling in mobile environment Alkılıçgil, Erdem; Erkmen, Aydan Müşerref; Department of Electrical and Electronics Engineering (2005) The popularity of e-commerce sites and applications that use recommendations and user modeling is increased recently. The development and contest in tourism calls attention of large-scale IT companies. These companies have started to work on recommendation systems and user modeling on tourism sector. Some of the clustering methodologies, neighboring methods and machine learning algorithms are commenced to use for making predictions about tourist̕s interests while he/she is traveling around the city. Recomme...
A monolithic approach to automated composition of semantic web services with the event calculus Okutan, Çağla; Çiçekli, Fehime Nihan; Department of Computer Engineering (2009) In this thesis, a web service composition and execution framework is presented for semanti- cally annotated web services. A monolithic approach to automated web service composition and execution problem is chosen, which provides some benefits by separating the composi- tion and execution phases. An AI planning method using a logical formalism called Event Calculus is chosen for the composition phase. This formalism allows one to generate a nar- rative of actions and temporal orderings using abductive planni...
Design and implementation of a privacy framework for web servicesin the travel domain Erkanar, Mehmet; Doğaç, Asuman; Department of Computer Engineering (2005) A web service is a collection of functions that are packaged as a single entity and published to the network for use by other programs. Web services are building blocks for creating open distributed systems, and allow companies and individuals to quickly and cheaply make their digital assets available worldwide. With considerable interoperability, privacy management becomes an inevitable concern of the web services. Companies and individuals should be able to restrict the information available about themsel...
A Static analysis approach for service oriented software engineering (SOSE) designs Çermikli, Can; Doğru, Ali Hikmet; Department of Computer Engineering (2010) In this thesis, a static analysis approach is introduced in order to develop correct business processes according to the Web Service Business Process Execution Language (WS-BPEL) specification. The modeling of the business processes are conducted with Business Process Execution Language (BPEL) which is a popular orchestrator of Service Oriented Architectures (SOA) based system through the description of workflow. This approach is also integrated to the Service Oriented Software Engineering (SOSE) design tec...
