Re: SUO: Re: Proposed SUO Content Outline




You might want to look at an approach to little theories based on
First-Order Logic, but modified so that one can still do IMPS like
theorem proving.  IMPS was based on higher-order type theory, however,
the IMPS authors have since realized that one can imbed partial
functions and undefined terms in the First-Order Logic framework.  They
developed a set theory with support for partial functions.  As with
IMPS, the new logic uses the method of interpretations between theories
to establish criteria for combining information in a fashion that
preserves the inferences already available in the original information. 

The framework turns out to be a nice foundation for evaluating
formalisms for a semantic web.  Take a look at:
