[ Lists Home | Date Index | Thread Index ]

A question I would have is if the operations that 
Sowa/Majumdar post in the cited article for CGs 
apply to analogical reasoning work on RDF.


Note that the authors begin by stating that:

"Logical and analogical reasoning are sometimes 
viewed as mutually exclusive alternatives but 
formal logic is actually a highly constrained and 
stylized method of using analogies.  Before any 
subject can be formalized to the stage where logic 
can be applied to it, analogies must be used to 
derive an abstract representation from a mass of 
irrelevant detail.  After the formalization is 
complete, every logical step -- of deduction, 
induction, and abduction -- involved the application 
of some version of analogy... The same operations 
used to process analogies can be combined with 
Peirce's rules of inference to support an inference 
engine.  Those operations, called the canonical formation 
rules for conceptual graphs, are widely used in CG 
systems for language understanding and scene 
recognition as well as analogy finding and 
theorem proving.  The same algorithms used to optimize 
analogy finding can be used to speed up all the 
methods of reasoning based on the canonical formation

I think it is a long reach to say that RDF is anywhere near close to CGs,
notwithstanding that you can draw a graph for each.
