Research approaches to diagrams

ABOUT DIAGRAMS....... 

• Diagrams are human artifacts, constantly evolving to support human activity.
• They are “qualitative” in the sense that they have (to date) escaped mathematical formalization.

Why important role in research ?         
• They are a rich domain for research: 
    – Drawing lessons from human perception and reasoning 
    – As a well-understood class of representational model
    – As a source of novel computation techniques• Diagrams as external representations
• Diagrams as internal representations
    – mental representations (humans)
    –computational representations (machines)
• Range of schematically / representation taxonomy
• Diagrams as language
    – elements & configuration versus lexicon & syntax
• Diagrams as qualitative models of the world
