Phenotype ontology

Phenotypes are not a static list. Their structure, specificity, and absence shape every downstream result.

Representation

Record exact terms, modifiers, exclusions, and ontology release.

Semantic structure

Test ancestor propagation and information-content choices.

Ranking stability

Measure which terms dominate candidate prioritization and why.

Questions we force the analysis to answer

Every output is evaluated against explicit interpretive tests.

  1. Which terms carry genuine discriminating information?
  2. How does ontology version change gene or disease similarity?
  3. What happens when uncertain or absent phenotypes are modeled explicitly?
