This paper describes a tool, called Nodose, we have developed to expedite the creation of robust wrappers. Nodose allows non-programmers to build components that can convert data from the source format to XML or another generic format. Further, the generated code performs a set of statistical checks at runtime that attempt to find extraction errors before(More)
Many analysis and monitoring applications require the repeated execution of expensive modeling functions over streams of rapidly changing data.
