In recent years, web services have become an emerging technology for communication and integration between applications in many areas such as business to business (B2B) or business to commerce (B2C). In this growing technology, it is hard to compose web services manually because of the increasing number and compexity of web services. Therefore, automation of this composition process has gained a considerable amount of popularity. Automated web service composition can be achieved either by generating the composition plan dynamically using given inputs and outputs, or by locating the correct services if an abstract process model is given. This thesis investigates the former method which is dynamicly generating the composition by using the abductive lanning capabilities of the Event Calculus. Event calculus axioms in Prolog language, are generated using the available OWL-S web service descriptions in the service repository, values given to selected inputs from ontologies used by those semantic web services and desired output types selected again from the ontologies. Abductive Theorem Prover which is the AI planner used in this thesis, generates composition plans and execution results according to the generated event calculus axioms. In this thesis, it is shown that abductive event calculus can be used for generating web services composition plans automatically, and returning the results of the generated plans by executing the necessary web services.

Automatic composition of semantic web services with the abductive event calculus Kırcı, Esra; Çiçekli, Fehime Nihan; Department of Computer Engineering (2008) In today's world, composite web services are widely used in service oriented computing, web mashups and B2B Applications etc. Most of these services are composed manually. However, the complexity of manually composing web services increase exponentially with the increase in the number of available web services, the need for dynamically created/updated/discovered services and the necessity for higher amount of data bindings and type mappings in longer compositions. Therefore, current highly manual web servic...
A service oriented collaborative supply chain planning process definition and execution platform Olduz, Mehmet; Doğaç, Asuman; Department of Computer Engineering (2008) Currently, there are many software applications handling planning, scheduling, material management, invoicing, workflow management within an organization. However, companies need to plan across a wider span of activities and need to collaborate with their partners to optimize the ''overall'' profitability. This requires collaborative planning within a supply chain and exchange of planning data. Collaborative Planning, Forecast and Replenishment (CPFR) is one of the most prominent initiatives on Collaborativ...
A migration management framework proposal for cobol/cics based mainframes Kaplan, Halil; Doğru, Ali Hikmet; Department of Computer Engineering (2010) Today, mainframes contain a considerable portion of business applications worldwide. It is estimated that the current inventory of production COBOL running on mainframes is 150 to 200 billion lines of code. Despite the efforts to change within the mainframe environment, these mainframes, nowadays, face major problems for host organizations due to a combined set of financial, business related, technical and organizational problems. Moreover, the factors like diminishing resources (COBOL programmers), lack of...
Design and implementation of a p2p contracting overlay Çelebi, Remzi; Polat, Faruk; Department of Computer Engineering (2009) Today, with widespread use of Internet in many areas, the common procedures frequently encountered in business life such as contracting and negotiation need to be automated. The distributed structure of the Internet and the difficulty of resources dispersed on one center makes such a system to have a distributed architecture . In this study, for first time, automatization of a contracting form through business processes was proposed and was carried out. A peer to peer process contracting overlay what we cal...
Execution of distributed database queries on a HPC system Önder, İbrahim Seçkin; Coşar, Ahmet; Department of Computer Engineering (2010) Increasing performance of computers and ability to connect computers with high speed communication networks make distributed databases systems an attractive research area. In this study, we evaluate communication and data processing capabilities of a HPC machine. We calculate accurate cost formulas for high volume data communication between processing nodes and experimentally measure sorting times. A left deep query plan executer has been implemented and experimentally used for executing plans generated by ...
