    Cdao Utep10 Cdao Utep10 Presentation Transcript

    • Comparative Data Analysis Ontology
    • Presentation Outline
      • Terminology
      • Basic Structure
      • Design Decisions
    • 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.
    • 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.
    • 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.
    • Additional Questions
