Data quality issues have taken on increasing importance in recent years. In our research, we have discovered that many “data quality” problems are actually “data misinterpretation” problems – that is, problems with data semantics. In this paper, we first illustrate…

This paper derives recursive algorithms for efficiently computing event probabilities related to order statistics and applies the results in a queue inferencing setting. Consider a set of N i.i.d. random variables in [0, 1]. When the experimental values of the…

The convergence of three distinct but interconnected trends - unrelenting globalization,
growing worldwide electronic connectivity, and increasing knowledge intensity of
economic activity - is creating powerful new opportunities and challenges for global
politics. This rapidly changing environment…
