Service Oriented Computing (SOC) is a popular computing paradigm for the development of distributed Web applications. Service composition, a key element of SOC, is severely hampered by various types of semantic heterogeneity among the services. In this paper, we address the various semantic...

In the era of Global Services, Service Oriented Architecture (SOA) has been gaining momentum for building Web-based information systems. Service composition is one of the key objectives for adopting SOA. Unfortunately, Web services are not always exactly compatible and it is a non-trivial task...

With the increasing popularity of Service Oriented Architecture (SOA), service composition is gaining momentum as the potential silver bullet for application integration. However, services are not always perfectly compatible and therefore can not be directly composed. Service mediation, roughly...

We present a method for estimating Markov dynamic models with unobserved state variables which can be serially correlated over time. We focus on the case where all the model variables have discrete support. Our estimator is simple to compute because it is noniterative, and involves only...

Crestor, an important but controversial cholesterol-lowering drug, is contraindicated for use by senior and Asian patients. In this paper, we exploit this fact and a unique doctor-level prescription and advertising (detailing, to be exact) exposure data for statin drugs to examine the hypothesis...

Cyber attacks are increasing in frequency, sophistication, and impact. Defending against them requires a new perspective on the attacks and the attackers. By applying a value-chain lens to the problem, we can better understand the dark web as an ecosystem in which well-orchestrated attacks are...

Cross-border data flows and interoperability have created an increasingly digital global trade environment. Concerns for cybersecurity, privacy, and digital sovereignty have prompted the widespread implementation of trade policies regulating cross-border data flows. At present, there is a...
