This research focuses on the question of why Wikipedia articles are different in quality. Since Wikipedia articles are developed in an open and social environment, our work investigates if social capital of Wikipedia contributors plays a role in determining the quality of Wikipedia articles. In...

Availability of increasingly rich biological data has tremendous potential for discovering new knowledge that is mostly found via the links among data sources. The current simple ways of implementing these links do not explicitly represent their semantics, and therefore, fail to provide useful...

The global adoption of RFID technology presents a number of challenges to IT architecture design. This paper identifies important requirements for RFID data provisioning at an abstract architecture level. A non-invasive architecture style is proposed to satisfy these requirements. Our proposed...

Cardinality constraints have been a useful and integral part of conceptual database design since the original entity-relationship (ER) model proposed by Chen. Subsequently many papers discussing classification frameworks for cardinality constraints have been proposed. Completeness of such...

The World Wide Web is transitioning from being a mere collection of documents that contain useful information toward providing a collection of services that perform useful tasks. The emerging Web service technology has been envisioned as the next technological wave and is expected to play an...

The impact of multi-channel technology-enabled digital goods on the sales of the physical counterpart faces uncertainty in the electronic commerce domain. We address the issue empirically by identifying the effect of the availability of digitally-delivered movies on physical DVD movie sales....

RFID-based technology for identification and tracking has potential to cut costs and provide strategic information for real-time decision support. To be useful, the generated data must be linked and distributed through the enterprise and the supply chain. We cannot achieve this kind of...

This thesis studies a single item periodic review inventory problem with stochastic demand, random price and quotation cost. It differs from the traditional inventory model in that at the beginning of each period, a decision is made whether to pay the quotation cost to get the price information....
