Background: Background: A common set of problems observed A common set of problems observed in implementing practical systemsin implementing practical systems

► Two industrial projects & one major research application using Ontologies & OWL with software

► Documentation & order entry software

► Make the right information / forms / widgets available at the right time tailored to patient, task and setting

► Minimize cognitive overload

► Links to many medical terminologies► ICD, SNOMED, Ontology for Clinical Research and other statistical ontologies, National Center

for Biomedical Ontology. GALEN, …

► Work on Protégé-OWL, OWL, and related formalisms► And living in a hot-bed of DL experts

► Experiments with NHS National Programme for IT standards & specifications

► Plus a question from one of the most prominent and successful researchers in Health Informatics

►Why can’t we get back to 1985? (hands thrown up in despair)

• Zak Kohane: Harvard based, MIT trained in AI & CS, amongst most experienced & successful NIH bioinformatics and translational medicine researchers

… … and the obvious observation:and the obvious observation:Ontologies have had little impact on software:Ontologies have had little impact on software:

► Artifacts called “Ontologies” have become ubiquitous►“Everybody thinks they need one” – sometimes just a

synonym for good

► …but…(outside this room)►Ontological methods and OWL remain niche markets

• Compare to “Model Driven Architecture” (MDA)‣ Where are the “Ontology Driven Architectures”

►Constant questions about how OWL relates to UML• … and few helpful responses

►Constant queries about relevance of ontologies• Minimal impact outside of “annotation”‣And limited there

- compare with XML, UML, and even RDF(S)

Plan of this talkPlan of this talk

► Where I come from► And my slant on the history of KR and Ontologies in Information Systems

► Our use cases► And why clinical systems are hard

► Architecture issues ► Dual use of ontologies and “Fractal tailoring”

► Ontologies, data structures, and user interfaces

► Knowledge issues► Language

► Generic Knowledge Representation & Contingent Knowledge

► Ontology issues► Ontology issues that do (and don’t) matter to clinical systems

► What’s in a code

► Metadata, Annotations, Higher order representations

► Evidence for choosing options, evaluation and quality assurance

► Summary of requirements and issue

Separation of Lexicon / Language and Separation of Lexicon / Language and Symbolic Model of “Ontology”Symbolic Model of “Ontology”

► “Ontologies” are symbolic models implemented in software / logic► Behaviour unchanged under any consistent relabelling

► Good practice is that every entity have a clear linguistic description as well as a label• But the descriptions and labels do not affect behaviour of the ontology in software

► Language and Logic use different principles► Lexicons are about word usage, grammar, etc.

► Many ways to express the same symbolic expression in language

► Synonymy, polysemy, metonymy etc. are linguistic phenomena and language specific

► Linguists and ontologists have surprising difficulty understanding each other

► Research on relation between language and formal ontology still limited despite• John Bateman, Pelletier

• MONNET project (UPM Asun Gomez Perez, Oscar Corho, …)

Language is often misleading wrt model &Language is often misleading wrt model &Arguments about words tend to dogmatismArguments about words tend to dogmatism

► Misleading►“Heart valve” ≠ “valve located the heart”

• Means one of the four “great heart valves”

►“Cardiomyopathy” ≠ “Disorder of cardiac muscle”• Otherwise a “Myocardial Infarction” would be a “Cardiomyopathy”.

► Words lead to more dogmatic arguments than substance►“Does ‘neoplastic’ imply ‘malignant’?”

‣ bitter controversy

►“Do we need expressions for all of…? - “Benign tumour” - “Malignant tumour” - “Tumour, benign or malignant”

‣ No controversy

►In all ontological formalisms, all statements begin with “for all…”

• Implied in DLs

• Explicit in predicate logic based formulations

• Expressed as lambda abstraction in Conceptual Graphs

• Generally true in frames, but ambiguous

► Example: parthood►Medical usage does not follow mereological theory

‣ Best modelled by a different relation: language is ambiguous

►“The thyroid is part of the endocrine system” is a matter of function rather than physical connectedness

• “faults in parts are faults in the whole” comes closer to clinical intuition• FMA driven to “Sets of heterogeneous structures” as a kluge

& the “immune system” has no parts!‣ Lack of functional information is major limitation on the use of the FMA

► The way we bridge the gap by a hierarchy of parthood relations

Bridging the gapBridging the gap

► Provide alternative organisations of the ontology►Let the classifier do the work

• But requires strict logical consistency & users’ intuitions are not always strictly logical

► Provide separate user organisation►Separate browsing / searching layer overlayed on ontology

• Thesauri and SKOS seem the natural candidates

• Systematic transformations between thesauri and ontologies a critical research area

Potential epistemic status is fundamental to Potential epistemic status is fundamental to medical reporting and reasoningmedical reporting and reasoning

► Most clinical systems distinguish at least two of: ►Observation: “Serum Haemoglobin = 7 mg%”

►Interpretation: “Serum Haemoglobin ~ low”

►Belief (diagnosis): “Anaemia”

► Ignoring potential epistemic status cripples an ontology for use in clinical systems

►Because different behaviours are required depending on the potential epistemic status

Whether they exist in the world is irrelevant Whether they exist in the world is irrelevant

► The information system may contain a representation of a nonexistent entity so that:

►Test for its existence ►Describe it if it is suddenly found to exist– ►Hold data “about it” when it was thought to exist►…

► Examples►The toxin responsible for AIDS►The gene for X ►Pneumonia caused by Trypanosome►The Higgs Boson►(even Unicorns – e.g. to say that “Narwhale may have been the origin

► Relation of prototypes, individuals fulfilling those prototypes, and collections of those individuals

►“Prototypes” authored pre-hoc and then realised in individual• Blueprints and buildings• Protocols for a trial, individual patient’s histories in the trial, data from the trial,

analysis and description of the data, description of the trial

►“Prototypes” abstracted post-hoc from observations of individuals

• Normative anatomy and biology• Almost all scientific “laws”

►Does the distinction matter? In theory? In practice? If so how?

► What does it mean to be “conformant” or “normal”? “abnormal”? “missing”?

Ontologies and Software EngineeringOntologies and Software EngineeringTowards multi layer models and Towards multi layer models and defined interfacesdefined interfaces

► “Ontologies” are not data models►Although data models may be motivated by “ontologies”

► Our understanding of the world vs how to store information about the world

►A data structure can have a missing entry for “heart beat”

►A (live) person cannot have a missing heart beat

► Ontology languages are really general logic languages

►Can be used to describe either,BUT NOT AT THE SAME TIME

► Detailed analysis in Beradi et al 2005(http://www.inf.unibz.it/~calvanese/papers-html/AIJ-2005.html)

►Described how to use DLs to describe data structures• Not the relation between Ontologies and Data structures

►Numerous tools and schemes since - but the same fault• E.g. OWL2XMI

• OMG Profile is largely syntactic and results in translations with unforeseen consequences

►The consequences for the information systems, e.g.• Expressivity, inferences

• Correspondence to users’ intuitions and usability

• Relation to standards and common practices

• Transformations between alternatives (morphisms)

• Flexibility, effort required for maintenance

• Complexity of queries

• Scaling

• …

►Consistency with the world as we best understand it• Are any of the consequences refuted when tested; unacceptable to users

►Implementations• Until implemented, it isn’t yet an “ontology for information systems”
