IFOMIS • Institute for Formal Ontology and Medical Information Science • Some background
The Manchester School • Kevin Mulligan • Peter Simons • Barry Smith • in Manchester 1973-76 • working on the ontology of Edmund Husserl
Logical Investigations¸1900/01 • the theory of part and whole • the theory of dependence • the theory of boundary, continuity and contact
Formal Ontology • (term coined by Husserl) • the theory of those ontological structures • (such as part-whole, universal-particular) • which apply to all domains whatsoever
Formal Ontology vs. Formal Logic • Formal ontology deals with the interconnections of things • with objects and properties, parts and wholes, relations and collectives • Formal logic deals with the interconnections of truths • with consistency and validity, or and not
Formal Ontology vs. Formal Logic • Formal ontology deals with formal ontological structures • Formal logic deals with formal logical structures • ‘formal’ = obtain in all material spheres of reality
Formal Ontology and Symbolic Logic • Great advances of Frege, Russell, Wittgenstein • Leibnizian idea of a universal characteristic • …symbols are a good thing
Warning • don’t confuse Logical with Ontological Form • Russell • Part-whole is not a logical relation
for Frege, Russell, Lesniewski, • Wittgenstein, Quine • Logic is a ‘Zoology of Facts’ • Formal theories are theories of reality • with one intended interpretation • = the world tragically after starting off on the right road
Tarski, Carnap, Putnam, Sowa, Gruber: • Forget reality! • Lose yourself in ‘models’!
IFOMIS Ontology • is an ontology of reality • Standard Information Systems Ontologies • are ontologies of mere 'models'
Standard Information Systems Ontologies: • programming real ontology into computers is hard • therefore: we will simplify ontology • and not care about reality at all
therefore • we will not try to paint the Palace at all • ... we will be satisfied instead with a grainy snapshot of some other building
IFOMIS Strategy • get real ontology right first • and then investigate ways in which this real ontology can be translated into computer-useable form later • NOT ALLOW ISSUES OF COMPUTER-TRACTABILITY TO DETERMINE THE CONTENT OF ONTOLOGY
a language to map these • Formal ontological structures in reality
Property Object a directly depicting language • ‘John’ ‘( ) is red’ Frege
are pictures of Wittgenstein’s Tractatus • Propositions • States of affairs
Parts and Moments • in a directly depicting language • all well-formed parts of a true formula are also true • (The Oil-Painting Principle) A new sort of mereological inference rule – the key to the idea of a directly depicting language
A directly depicting language • may contain an analogue of conjunction • p and q • _______ • p
but it can contain no negation • p • _______ • p
and also no disjunction • p or q • ______ • p
The idea of a directly depicting language • suggests a new method • of constituent ontology: • to study a domain ontologically • is to establish the parts, qualities and processes of the domain • and the interrelations between them
BFO and GOL • Basic Formal Ontology (BFO) • BFO as an ontological theory of reality designed as a real constraint on domain ontologies • (as opposed to conceptual modeling ...)
A Network of Domain Ontologies • Material (Regional) Ontologies Basic Formal Ontology
Ontology • seeks an INVENTORY OF REALITY • Relevance of ontology for information systems, e.g.: • terminology standardization • taxonomy standardization • supports reasoning about reality
BFO • Basic Formal Ontology • = a formal ontological theory, expressed in a directly depicting language, of all non-intentional parts of reality • (an ontology of the whole of reality but leaving aside minds and meanings)
