Real-Time Model Checking for Shill Detection in Live Online Auctions

Haiping Xu, Christopher K. Bates, S. Shatz
Computer Science
Software Engineering Research and Practice
2009

In this paper, we introduce a dynamic auction model (DAM) for real-time detection of shilling behaviors in live online auctions. Expand

ADK: An Agent Development Kit Based on a Formal Design Model for Multi-Agent Systems

Haiping Xu, S. Shatz
Computer Science
Automated Software Engineering
1 October 2003

The advent of multi-agent systems has brought us opportunities for the development of complex software that will serve as the infrastructure for advanced distributed applications. Expand

A Real-Time Self-Adaptive Classifier for Identifying Suspicious Bidders in Online Auctions

Benjamin J. Ford, Haiping Xu, Iren Valova

Comput. J.
1 May 2013

We introduce a Real-Time Self-Adaptive Classifier (RT-SAC) for identifying suspicious bidders in online auctions using an incremental neural network approach. Expand

Reasoning under Uncertainty for Shill Detection in Online Auctions Using Dempster-Shafer Theory

F. Dong, S. Shatz, Haiping Xu
Computer Science
Int. J. Softw. Eng. Knowl. Eng.
1 November 2010

This paper describes the design of a decision support system for shill detection in online auctions, and shows that it can be used to detect shills effectively and efficiently. Expand

Automated Modeling of Dynamic Reliability Block Diagrams Using Colored Petri Nets

R. Robidoux, Haiping Xu, Liudong Xing, M. Zhou
Computer Science
IEEE Transactions on Systems, Man, and…
1 March 2010

We present a procedure for formal modeling and verifying DRBD for computer-based systems and present an algorithm that automatically converts a model into a colored Petri net. Expand

Combating online in-auction fraud: Clues, techniques and challenges

F. Dong, S. Shatz, Haiping Xu
Computer Science
Comput. Sci. Rev.
1 November 2009

The number of Internet auction shoppers is rapidly growing. However, online auction customers may suffer from auction fraud, sometimes without even noticing it. In-auction fraud differs from pre- and… Expand

A Framework for Model-Based Design of Agent-Oriented Software

Haiping Xu, S. Shatz
Computer Science
IEEE Trans. Software Eng.
2003

In this paper, we customize the basic G-net model to define a so-called "agent-based G-nets" that can serve as a generic model for agent design. Expand

Part family formation for GT applications based on fuzzy mathematics

Haiping Xu, Hsu-Pin Wang
Engineering
1 September 1989

Group Technology (GT) is one of the key issues in a successful implementation of flexible manufacturing systems ( FMSs). The objective of GT is, through the use of a part-family (PF) formation… Expand

A Multi-State Bayesian Network for Shill Verification in Online Auctions

A. Goel, Haiping Xu, S. Shatz
Computer Science
SEKE
1 December 2010

In this paper, we introduce a novel approach for verifying shill bidders using a multi-state Bayesian network, which supports reasoning under uncertainty. Expand
