Technological advances such as Service Oriented Architecture (SOA) have increased the feasibility and importance of effectively integrating information from an ever widening number of systems within and across enterprises. A key difficulty of achieving this goal comes from the pervasive...

As Industrial Control Systems (ICS) become increasingly software-intensive and morecomplex, the traditional approaches to cybersecurity that undertake a narrow, static technical view of the system are proving to be increasingly inept in the face of new threat vectors and vulnerabilities. To...

In December 2015, coordinated cyberattacks targeting Ukrainian power distribution systems’ information technology (IT), industrial control systems (ICS), and operational technology (OT) resulted in physical damage to Ethernet serial converters, intentional disabling of distribution facility...

We examine semantic interoperability problems in the fixed income securities industry and propose a knowledge representation architecture for context interchange mediation to support dynamic integration of autonomous database, web, and procedural sources of information. For sources and receivers...

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...
