The DS2 Inference Analyzer is a web application to:

  • Visualize patients’ clinical concepts and co-occurrences
  • Evaluate predicates to asses predictive capabilities
  • Leverage predicates to make inferences, find “missing” concepts, “hide” concepts, view impact of edits/redactions

Source code, documentation, and build instructions are available in the SimplePredicateReducerVisualizer project on the SHARPS DS2 Bitbucket site. For a working demonstration, see the Demonstrations page.
