This should be the age of knowledge acquisition

• The Web– Social computing & Web II– The Semantic Web/Grid

• Service oriented Architectures and discovery– Digital libraries, repositories, ...– Semantic computing

• “Ontologies with everything”

• ...

• ...“... but couldn’t we just get back to 1985”

The knowledge principle

• A system exhibits intelligent understanding and action at a high level of competence primarily because of the specific knowledge that it contains about its domain of endeavor.– Ed Feigenbaum: The Age of Intelligent Machines:

Knowledge Processing--From File Servers to Knowledge Servers, 1990

• Knowledge comes from domain experts:Derived from and delivered to the problem space

Page 7: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

…and a Key Reference Point

• We argue that logical soundness, completeness, and worst-case complexity are inadequate measures for evaluating the utility of representation services, and that this evaluation should employ the broader notions of utility and rationality …”

– Two theses of knowledge representation: Language restrictions, taxonomic classification and the utility of representation services.Doyle, J and Patil, R, Artificial Intelligence, 1991. 48: p. 261-297

By way of User Centred DesignOntologies were a solution, not a goal

Page 10: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

… and now to• BioOntologies, Anatomy, and Molecular Pathways

– Capturing biologists knowledge– Reconciling diverse views / Avoiding ontological dogmatism– Integrating ≥500 sources

• Healthcare record standards: Data models and Terminology– Improving the rigour of “UML” based message standards– Binding of terminology to data models

• Medical terminologies / ontologies– GALEN, SNOMED, NCI thesaurus

• Forms generation for clinical trials, data entry & entry and decision support.

– PEN&PAD Revisited

• User oriented Ontology Tools - CO-ODE/Protégé-OWL

• Semantic Web Best Practice WG & Healthcare & Life Sciences SIG(& campaigner for OWL 1.1 and beyond)

Some Recent User Experiences

• Two companies building clinical systems– Intelligent forms creation and constraint management

• Mastering a combinatorial explosion of ≥107

– Workshops, Training and subcontracting

• NHS National Programme for IT: – Additional constraints to UML and between UML and

terminology/ontology• Different implementation of the standard don’t fit

– Managing SNOMED• Large ≥450K ters DL based terminology

• Biologists research groups– Many clinics and workshops

• indefinitely many emails on HCLSig

• The Anatomy community– Workshops towards a common vertebrate anatomy

• “Can’t we just get back to 1985”

What are my prejudices?

• “First do the right thing; then do it right”– and hope that by the time you know what to do

someone else can show you how

• “There is no one way!”– “Society for the Promotion of Secular Ontology”

• “Better” is better than “best”– The best is often the enemy of the good

• Unobtrusive assistance is better than advice– “Shedding light” rather than “uttering prophecies”

• “It doesn’t make the coffee!”– Nothing does everything - the secret is in factoring

the solution space to fit the problem space

Who are my users?

• Intermediate users– Clinical terminologies developers

• GO, SNOMED, GALEN, CCAM, FMA, …

– IT staff configuring clinical systems• NHS, Healthcare information systems staff

– Standards developers• BioPAX, HL7, ??ML,…,

• Near to end users– Bioinformaticians– Trialists and other specialist healthcare informaticians

• End users– Biolomedical scientists– Clinicians, carers and patients

The rest of the talk

• Our experiences– Our original application:

Fractal tailoring of data input forms– Building large terminologies

• Logic as the clips for “Conceptual Lego”• Untangling and normalisation

– Working with biologists

• Observations on Knowledge Resources and “Ontologies”– Things we have found – Things we need

Page 15: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Where we started:A Vision

• Useful and Usable clinical systems– Information when and where you need it

• to make better decisions– “Shedding light”– “Cuing”

– In your own language

• Aggregated data as a byproduct of clinical

• …without getting caught in the combinatorial explosion

But there are combinatorially many possible forms

• The PROMIS system was discontinued in 1987 at 70K forms and accelerating– A major influence on our work

• For us KR is a way to avoid combinatorial explosions

• A supplier recently expanded all XML forms for data capture in one clinic to 107

Page 31: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Ontology normalisation:Enforced modularity

• All primitives form disjoint trees

• All polyhierarchies formed by inference from definitions– No arbitrary subclass axioms

• Therefore– All concepts have most specific primitive ancestor– No disjunctions in domain and range constraints

• Consequences– Changes occur in exactly one place– Defeasible inheritance can be constrained so that each

property inherited only along one taxonomy• The same property cannot apply from two different sources

that unless one subsumes the other

Matching problems and solutions The science & craft of KA

• Patterns, guidelines and tools

• Reformulations of users’ “solutions”

• Collaborations betwee behavioural & domain scientists

• Challenges and demonstrations

Some observations…

Page 47: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Working with users:The basics - I hope I am “teaching grandma to suck eggs”

• Do something useful - First do the right thing!

• Make it usable– Find a champion & early adopters– Embrace users’ attempts at solution

• At least it is probably useful– an example; a working specification

– Watch, ask, listen, and believe• There is no point in arguing with somebody that it is easy• There Is no point in arguing with somebody that they understand• Get help -

– Involve behavioural scientists– Use language and images - involve linguists

• Involve the implementers• Build for feedback

• Accept that clever things may be useless

The interesting may not be useful

• Of medical decision support systems in the literature in 1995– 70% addressed diagnosis

• Success rate of evaluated medical decision support systems in the literature in 1995– Alarms 75%– Treatment Management 65%– Diagnosis 17%

And you can only tell if its useful if you know “What’s it for?”

• Tens of Millions spent on SNOMED’s 450K codes– Only 10K have ever been used

• Many applications find 50%-75% missing

• Hard to predict users’ needs– So build it “just in time” if possible– And based on evidence

• Mine the web• Mine corpora• Observe users• Build in feedback

Page 50: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Some arguments only have answers wrt problems

• Open vs closed world reasoning– Querying Rail Timetable:

“Is there a train from Podebrady that gets me to Prague tonight?”

• “No”– Possibly false, but useful

» I can’t get better information• “Might be”

– True but not useful & possibly misleading

– Querying FoaF“Does Alan have any friends?”

• “Don’t know”– At least not misleading

• “No”– Wrong

(I hope)

Page 51: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

…which emphasizes again that:

Metaknowledge is knowledge

• The railway timetable is presumed complete– But how do I know?

• Do I trust the resource to tell me or depend on my experience?

• Biographies in FoaF are probably incomplete– But how do I know?

• What about some other data somewhere on the Semantic Web?

• Need some new metadata standards urgently

Page 52: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Get the user’s to own it

• The Gene Ontology is the most successful “ontology”/ “thesaurus”– Not rigorous; many faults– But owned by the biologists and does their job

• The Gene Ontology Next Generation project accepts and delivers in their format– The OWL is just another quality assurance tool

Page 53: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

QA with users:The Logical answer isn’t always the right answer

“Slashed wrist”

“Cardiovascular Disorder”

The user is right - fix the axioms:

“Cardiovascular Disorder”

“Disorder or injury of Heart or Great Vessels or arterial system as a whole”

“Self inflicted laceration of radial artery”

“Disorder or injury of Heart or blood vessel”

Page 54: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

…but may have to deal with differences in logic and language

• Logically:Four limbed animals do not subsume four legged animals– unless we represent explicitly our background

knowledge that four legged animals have no other limbs

• but we never say it• how to convey the intuitions to users?

Page 55: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Expressivity is more important than constraints

• Draw all the inference the user expects from “sensible” premises– Users won’t mind if wrong inferences could have

been drawn from nonsense premises• Provided the nonsense premises can’t get in by

accident

Find a way to do it: nonstandard reasoning:

Commonalities and differences

• Classify all the proteins with phosphatase1 activities– Identify all the features in common

• Simple subgraph algorithm

– Create the generic abstraction– Classify again to find more phosphatases

• 20 new phosphatases– Some probably implicated in disease

– Classify by which tissue they come from• Repeat

– Try to understand why some tissues suffer from disease and some don’t

1”Phosphate-ase” - enzyme that breaks down phosphate bonds; the primarysource of energy in cells; can drive super-oxidation; prime source ofdamage in diabetes, extreme inflammation in Intensive Care Units, atherosclerosis, and probably much else

Hide formalisms Focus on meta-modelling

• Make the logic the assembly language– Build “compiler compilers” for close to user forms

• Ought to be a major focus of our research

– Transformations, import, export

• Support implementors and localisers– Tools to build user oriented special purpose tools,

languages and interfaces

• Build quick tools for common patterns– Tabbed outlines for taxonomies– Easy visualisation and specification of disjoints– Wizards and Patterns for features & value sets– Special tools for lists– …

Language Generation(an often forgotten technology)

• Even simple language generation helps– Even logicians may find it easier to work in

pseudo-natural language

• If not natural language at least intuitive syntax– Syntax matters to understanding

Seek evidence

• Use corpora, NLP & the Web– Experts often wrong about what really happens

• Beware of committee views• Beware of dogma

Prioritize issues to users’ requirements - thank you OWL 1.1

• Role assertions– “Fracture of neck of femur” is a kind of “Fracture

of Femur”• hasLocus o isPartOf →hasLocus

– Accept repurposing• There are alternative solutions for anatomy but

essential for other cases– “Uncle”– “Reified relations” (Ontological “qualities”)

Test at scale

• Many users’ problems are BIG– Biological examples ≥ 10K concepts – Medical examples 20K…500K concepts

Use � the tricks of the trade (especially to reduce arguments)

• “Pericardium” (covering of the heart) & “Heart”: – To anatomists: they are two different organs– To the clinicians: they are parts of the same

functional unit

• The role hierarchy can let us support both views is_clinical_part_of

← is_structural_part_of

…but hide them from (most)

users• Neither the anatomist nor the surgeon need

to know about the other– In GALEN we had several different variants of

the intermediate representation compiler to deal with intractable arguments

• QA always passed by all

Make representations maintainable & evolvable(basic software engineering)

• Don’t be too clever(Avoid “Write once read never”)

– “Shortest S-Expression for a function”“Maximum code in a C ‘for’ statement”

– “Clever” inference in an OWL KB• Avoid

– Making inferences from domains/range» May better to check before inference * Or do inference in multiple step

– Complex disjoint axioms and disjunctions

• Design so all changes made in only one place– Normalise ontologies

• Be systematic - follow patterns

• Provide regression testing from the beginning– Preferably before building

• Support debugging

Remember: Your part is only one source of errorIt will require empirical testing

• Errors come from– Errors & low inter-rater reliability in input

• Often under 80%

– Implementation errors in applicxations– The perversity of the universe - the Rumsfeld effect

• It is going to require empirical testing– The ONLY test that will be accepted for most

applications is empirical• Whether or not the algorithms are complete

My top next priority for OWL:

“What is it sensible…

• To ask– Everything is permitted unless it is forbidden

• Natural open world logical view– Sets of constraints

• To tell (sanctioning)– Everything is forbidden unless it is permitted

• Natural frames/OO/UML view– Sets of templates

Page 70: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

But the basis for intelligent user interfaces

Needed by every user we have encountered

• It is sensible to ask about “Green entities”– There are entities that are green

• It is not sensible to ask about “Green dreams”– No: dreams have no colour

• The more I know the less it is sensible to ask

• Is it sensible to tell that balls are green?– If it might sensibly be green

• The more I know, the more it is sensible to tell– A hard/impossible notion to capture in first order theories

Page 71: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Related: “Optional”

• What are the semantics of :– 0..n in UML?– or canonical graphs in Conceptual Graphs?– or sensible sanctions in GRAIL?– or slot attachment in Frames?– or minCardinality(0) in OWL?

• Supported by every formalism any user will ever have used– There must be something to it

• Even if it isn’t first order

• Needed by every data application we have encountered

Page 72: Whose knowledge? Whose questions? Whose answers? Conflicting Preconceptions for Knowledge Intensive Systems Alan Rector School of Computer Science, University

Related but different:“May”

• May – “What may cause pneumonia?”

What classes of bacteria may cause pneumonia?• Hard to express in DLs/OWL

– Need richer relations amongst properties» causes → may_cause

Almost captures it» “Anything that acts has the potential to act”

“Anything that does not have the potential to act, cannot act”…is there additional semantics?

» Very messy without special tools and operators in user language

… others needs for a better

match to biomedical knowledge

• Prototypical knowledgeThe heart is generally on the left but sometimes on the right

– Normative solutions OK for some things• “The normal hand has five digits”

• “The normal heart is on the left”

– Simple explicit exceptions OK for some things• “All human cells have nuclei except red blood cells”

– But otherwise need prototypical knowledge & exceptions• “Typically birds fly”

• “Typically gram positive bacteria are penicillin sensitive”

• Uncertainty - another step? a different formalism?– 70% of appendices are in right lower abdomen

• Can fuzziness/probability/… be contained in the same framework or do we need a true hybrid system?

– Needs to link to utilities and decision theory
