Crowdsourcing is a business model which allows practitioners to access a rather cheap and scalable workforce. However, due to loose worker-employer relationships, skill diversity of the crowd and anonymity of participants, it tends to result in lower quality compared to traditional way of doing work. Thus crowdsourcing practitioners use certain techniques to make sure the end product complies with the quality requirements. Each quality assurance technique used in crowdsourcing impacts the project cost and schedule. A well-defined method is needed to estimate these impacts in order to manage the crowdsourcing effectively and efficiently. This study proposes a cost of quality approach for analyzing quality related costs in crowdsourcing and introduces the cost models of common quality assurance techniques.

Cost Models of Quality Assurance in Crowdsourcing
Iren, Deniz; Bilgen, Semih (2014-08-01)
Even though crowdsourcing was introduced as a novel business model for risk prone entrepreneurs, in time it has become a valid means of producing value in large scale projects as well. However due to loose employee - worker relationship, quality continues to be a serious issue for crowdsourcing. Therefore, various quality assurance mechanisms are used in crowdsourcing. Quality assurance significantly impacts project costs. However the literature lacks defined ways to estimate costs of quality and guidelines...

Soylu Nazlı, Duygu; Bakal, İsmail Serdar; Savaşaneril Tüfekci, Seçil; Department of Industrial Engineering (2021-3-17)
Many companies in project-based industries manage their inventories in a decentralized manner on a project-by-project basis. Even if one project has excess supply of a material, the other may have excess demand of it, which increase inventory costs of the company. These costs can be decreased if material transshipments between projects are allowed. In this study, motivated by the defense industry applications in Turkey, we investigate ordering decisions of two different agents, who make inventory decisions ...

Using ontology based web usage mining and object clustering for recommendation
Yılmaz, Hakan; Karagöz, Pınar; Department of Computer Engineering (2010)
Many e-commerce web sites such as online book retailers or specialized information hubs such as online movie databases make use of recommendation systems where users are directed to items of interests based on past user interactions. Keyword-based approaches, collaborative and content filtering techniques have been tried and used over the years each having their own shortcomings. While keyword based approaches are naive and do not take content or context into account collaborative and content filtering tech...
Determining online consumer typologies and their shopping behaviors in B2C e-commerce platforms
Huseynov, Farid; Demirörs, Onur; Türetken, Oktay; Department of Information Systems (2016)
Business-to-consumer (B2C) e-commerce is the service or product exchange from businesses to consumers over the Internet. B2C e-commerce enables customers to easily compare offered products and services, to find cheaper and better ones from many alternatives and to shop from any given store without physically visiting them. Despite those conveniences provided by B2C e-commerce, a large number of customers prefer to stay away from the idea of shopping over internet due to several factors. For better customer ...
