Notice of recording

Discuss this paper in light of the new drug model. Specifically how the new model resolves many of the issues with incorrect inferences related to the IS A hierarchy in substances.

Smashing the strict hierarchy

• Batch editing of the disorder/findings hierarchy to transform it into a representation with a "naked kernel" clinical entities hierarchy (no soft defaults)
• Additional auxiliary hierarchies supporting better modeling patterns
• An observation/statement/assertion/phenomena hierarchy that would explicitly represent context (e.g. presence/absence) while supporting correct aggregation of some absence patterns.
