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...

We examine a knowledge representation architecture to support context interchange mediation. For autonomous receivers and sources sharing a common subject domain, the mediator's reasoning engine can devise query plans integrating multiple sources and resolving semantic heterogeneity. Receiver...

We use a context interchange mediation approach for detecting and resolving data quality and semantic integrity conflicts in information exchanged across organizational boundaries. Context models draw on a domain ontology to explain how source and receiver data models implement general...

Source selection allows the users to express what they want while the system automatically performs the identification and selection of relevant sources to answer the query request. To automate that process, the system must be able to represent the contents of data sources in a description...

Corporate household not only refers to the strict hierarchical structure within the corporation, but also the variety of inter-organizational relationships. We propose a conceptual definition for corporate household, corporate household knowledge, and corporate household knowledge processor....

The eXtensible Markup Language (XML) offers many important benefits and improvements over its predecessor, HTML. But, articles have appeared about XML with exaggerated claims of it being a "Rosetta Stone" with "miraculuous ways" to almost automatically provide information integration. These...

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 some examples of these...

One of the appealing features of artificial intelligence is the ability to come up with the “right” answer automatically, faster and more reliably than humans. In many cases, the right answer is singular and unambiguous, such as 2 + 2 = 4 (3.9 or 4.1 are close, but not right.). But, as is...

Physical control systems are increasingly controlled by reconfigurable, network-enabled devices to increase flexibility and ease commissioning and maintenance. Such capability creates vulnerabilities. Devices may be remotely reprogrammed by a malicious actor to act in unintended ways, causing...

The shift towards global networking brings with it many opportunities and challenges. In this paper, we discuss key technologies in achieving global semantic interoperability among heterogeneous information systems, including both traditional and web data sources. In particular, we focus on the...
