Top-Down Bottom-Up Methodology



Greetings SUO Subscribers,

	I remember this group discussing a methodology for extending an
upper ontology that we referred to as 'Top-Down Bottom-Up.'   Does
anyone know of any papers written to describe this.  

	Here's more to describe what I'm talking about.  If we develop
an ontology Bottom-Up, it may meet a specific need, but will not
interoperate with other ontologies.  If we start with an upper ontology
and extend just Top-Down, it probably won't meet the specific needs of a
given system.  The solution is to do both at the same time and iterate
until the ontology is both a clean top-down extension and also expresses
the Bottom-up semantics needed by specific systems.   So, is anyone
aware of any papers written to explain this?  (Software Engineering has
something they call Top-Down Bottom-up, but it's a different concept for
a different purpose.)
