Re: [ontolog-forum] Computer science ontology vs. philosophical ontology

Ed,

One more important terminology that computer science, software engineering and system engineering  people use -
 " Algorithms"  which use the mathematical concepts and logical flow for the process for subroutines, for calculation, data processing,  and automated reasoning etc.   People may remember using recursive algorithms in programming languages like  C, Pascal and Ada etc..

In Knowledge engineering,  people use -  Axioms and Logic and reasoning.

Thanks

Ed,

Thank you, that is very well said. 

 I used the word "behavior",  which is the processing aspect of the program or subroutine.  Probably "processing"  is a better word.    Initially  we agreed on both data and processing as part of Ontology.   

I agree with your explanation  about knowledge engineering as well reasoning etc..    This  group is intense about logic, axioms etc.. and this has been discussed before.   

Software engineers use terms  like,  various Life Cycle methodology,   Analysis, design,  implementation, modeling  techniques for data and processing  for programs and not necessarily, use the term " axioms" .  Slightly different terminology used .

With all due respect, Pavithra, I would have said:

 

“Data modeling” is the abstract representation of real world things  with a specific purpose, i.e., to  develop systems and simulate behavior of real world things relevant to the system by modeling them. 

 

“Knowledge engineering” is a special case of “data modeling”, where the systems in question involve computational implementations of “reasoning” and “logic”, and the model itself includes the formalization of some part of the behavior as “axioms”.  “Computer Science Ontologies” are artifacts of the knowledge engineering process – they are the models intended as data for use by the reasoning software.  In a certain sense, they are the “programs” or the “subroutines” for the reasoning engine, in much the same way that Excel spreadsheets are data and programs for a tabular computation engine.

 

I don’t expect that the Computer Science community in general will agree with the above terminology, but it is at least necessary to sort out those concepts and give them names.  The data model in every software program since 1955, even when an entity was expressed as Block Ended by Symbol, is an “abstract representation of real world things with the specific purpose ... to develop [that] system.”  Using “ontology” with that meaning does not advance the discipline.

 

That said, I intend to remain silent on the subject of the relationship of computational ontologies to philosophical ontology.  To me, that is “How is a raven like a writing desk?”

Simon,

Computer Science Ontology is the abstract representation of Philosophical Ontology and real word things  with a specific purpose ie to  develop systems and simulate behavior of real world things relevant to the system by modeling them.

In  computer science,  one can prove the existance of a thing by it's attributes ( what it consists of) ,  associations ( relation to other things)  and actions  ( what it does and behavior ) !    And there are real things and imaginary things.   

Philosophically, an ontology should do the same, prove the existence of something. 

 

Your understanding of philosophical ontology and of computer science cannot, then, be distinguished.
