Transcript

  • 1. Comparative Data Analysis Ontology
  • 2. Presentation Outline
    • Terminology
    • Basic Structure
    • Design Decisions
  • 3. Termonology
    • Taxon
      • Refers to an organism identifier
      • Names are controlled by external vocabularies such as NCBI
    • Trait
      • Some attribute of a set of organisms being studied
    • Tree
      • A graph specifying the inferred relationship between taxa in a study
    • Matrix
      • A matrix is defined as a set of taxa and traits and their associated states.
  • 4. Basic Structure
    • Network/Tree
      • Specifies all classes related to defining cdao trees.
      • Includes notions of node and branch
      • The actual relationship between nodes is specified in terms of properties such as child and parent
    • Matrix
      • Contains a set of traits and taxa.
      • Traits and taxa are connected to observed state data through the “has” property.
  • 5. Design Decisions
    • Data were categorized generally as:
      • Categorical
        • Molecular
          • DNA, RNA, or Protein data
        • Standard
          • Other discrete data such as color
      • Continuous
        • Continuous data such as beak-length
    • Class vs Individual
      • We made the decision to treat specific amino acids or nucleotide bases as individuals rather than classes.
  • 6. Additional Questions
