Abstract: Our work to date in connecting risk tools hs had successes, but also has revealed there to be significant impediments to information exchange between them. These impediments stem from the well-known phenomenon of "semantic dissonance" - mismatch between conceptual assumptions made by the separately developed tools. This issue represents a fundamental challenge that arises regardless of the mechanism of information exchange. This paper explains the issue and illustrates it with reference to our experiences to date connecting several risk tools. We motivate this work, present and discuss the solutions we have adopted to surmount these impediments, and the implications this work has for future efforts to integrate risk tools.
