RE: [emergency] Kent State Symbology Study

["Bullard, Claude L (Len)" <clbullar@ingr.com>]

Note that the definitions of symbols as abstract (indexical or symbolic) or replicative (iconic) may be better

classified in semiotic theory from Peirce.  See

 

http://www.jfsowa.com/pubs/signproc.htm

 

"In classifying signs, Peirce used his trichotomy to subdivide the sign relation into the triad of icon, index and symbol: an icon represents an object by its inherent form, which resembles the intended object; an index represents its object by some causal relationship, such as a pointing finger, a weather vane, or a dial on a meter; and a symbol represents its object by a convention established by some community."

The following is a link to the Emergency symbology study performed by Kent State for FEMA that was mentioned in today's XML committee call.
