Linyun’s Presentation

  • Linyun’s Presentation about Data Theory: Wickett et al.’s and Mealy’s papers
    • Traditionally, data types are creeping
    • GH Mealy’s 1967 paper: real world >>> our theory >>> machine representation
    • Entities, values and data maps: data map as
    • signs value to attribute of entity
    • Structural maps and pointers
      • structured map: value is the entity itself  – use of pointer
    • Procedure and data processing
    • Access functions and data organization
    • Data description: a specification of machine data systems and representations
    • Data type: a fragment of data description, describing an entity and its application maps
    • Machine independence or representation independence, the latter!
    •  It’s about TRIPLES! Data science and RDF in now days are not a building in the air!
    • Wickett’s scientific data representation model 2012
    • Propositional content >>> symbol structure >>> Patterned matter and energy
    • Linyun: it provides a formal way to describe what provenance information is important. The model provides a list of items for such description
    • Mealy describes the real world to data structure to data; Wickett describes the provenance feature of a model
