Electronic commerce is becoming more important day by day. Many transactions and business are done electronically and many people do not want paper work anymore. When a firm wants to buy raw materials or components, it announces its need to related websites or in the newspapers. Similar demands and announcements can be seen almost everywhere nowadays. In this way, it needs to perform fast and reliable auctions as much as possible. On the other hand, buyers not only consider cost but also consider a lot of different aspects like quality, warranty period, lead time etc when they want to purchase something. This situation leads to more complex problems in the purchasing process. As a consequence, some researchers started to consider auction mechanisms that support bids characterized by several attributes in addition to the price (quality of the product, quantity, terms of delivery, quality of the supplier etc.). These are referred to as multi-attribute combinatorial auctions. In this thesis, Combinatorial Auctions are analyzed. Single-attribute multi-unit, multi-attribute multi-unit combinatorial auction models are studied and an interactive method is applied for solving the multi-attribute multi-unit combinatorial auction problem.

A New search engine ontology for visually impaired users Akkaya, Ezgi; Karagöz, Pınar; Betin Can, Aysu; Department of Information Systems (2015) In today’s world, semantic technology is getting more and more important day by day. After Web 3.0, semantic infrastructure has become a must for internet based systems. In this thesis, we have focused on the semantic basis of search engines. Google, Yahoo, Yandex and Bing are the most popular search engines. All of them have a semantic structure, however the semantics have been developed according to the users who have not any visual impairment. In this study, search engine ontology has been developed acco...
Provision of market services for eCo compliant electronic marketplaces Arpinar, S; Doğaç, Asuman (Association for Computing Machinery (ACM), 2000-09-01) The progress and wider dissemination of electronic commerce will be facilitated through interoperability infrastructures. Commerce Net's eCo framework is a promising effort in this direction. In the eCo framework, businesses participate in a marketplace through standard interfaces for their services and by exchanging standardized documents. This framework does not specify any further interfaces for the services a marketplace itself may offer.
A Secure and Efficient Protocol for Electronic Treasury Auctions Bektas, Atilla; Kiraz, Mehmet Sabir; Uzunkol, Osmanbey (2014-10-17) Auctions have become an important part of electronic commerce. Considering the gradually increasing importance of confidentiality and privacy in auction modeling, various designs have been proposed to ensure secure transmission especially in sealed-bid auctions. However, to the best of our knowledge there is no secure and privacy preserving Treasury Auction system. Looking at systems currently in use, many countries perform those auctions manually. Since all the bids are transferred to the system in clear f...
