Standards and ontologies – changing the value proposition

Clinical Standards Workshop

Scope of today’s meeting• Challenge:

– Understand why implementation, curation, and recording against ontology/standards is so challenging

• Existing Solutions:– Understand the existing standards, tools, and ontologies that

can be leveraged and identify what specific improvements can be made

• Future Improvements: – Define how current tools can be leveraged for greater uptakes

by stakeholders

Clinical Standards Workshop

My COI Declarations• I was an academic for 10 years, worked with

various communities OBO, W3C• Worked with pharma before and after and I’m

now commercial• I founded EFO ~8 years ago• I’m married to a former curator, now developer

(she’s paid more as a developer – this is important because I’m going to talk about value)

Oct 2016

Clinical Standards Workshop

The Challenge• Two components I want to talk about:• Technical – hard for users• Institutional – evaluating the value

proposition

Technical Challenges• CDISC is a wonderful

thing• Has helped harmonise

clinical templating in amazing ways

• But it’s complicated…• Domain has a vast

range of technical skills

Technical challenges• There are 519 bio-ontologies – where do start?

Oct 2016

• Ontologies are directed graphs, graphs are complex• So much so there’s a mathematical discipline;

Graph Theory, so it must be hard

Ontologies reflect biology, so they’re complicated

Clinical Standards Workshop

Finding the right terms• How does a user know if the term is right?• How does a user know which ontologies to use?• How does a user report an error or a missing term?• In www these things are easy to do, e.g. wikipedia

– search, edit, comment, etc.• Users have come to expect this of most online

resources• And so they should

Clinical Standards Workshop

Language in ontologies • Can be obtuse, opaque, mired in philosophy, not always written in user’s

domain language• Can be effective in capturing knowledge but not in communicating to the user

Oct 2016

Page 11: Embedding Clinical standards in research workshop

Clinical Standards Workshop

Ontology speak a different language• Assay class• Translation:• an assay is a planned process which

evaluates a material and produces a measurement on that material

• User should not see that… • …but how then can they evaluate the

fitness and correctness of the class?• Accessibility barrier – also barrier to

engagement?

Clinical Standards Workshop

Institutional Challenges• Harder than technical – about mindsets• Curation is perceived as a ‘separate job’• Process is seen as:

– Slow– Manual– Expensive– Of lower value than pure “Big Data” approaches

• “I do not have budget to hire curators” is something I’ve heard recently from multiple sources

• Does ontology use/applying standards buy you anything?

• Curators are probably the best fit for skills required

• And arguably the least ‘in-demand’

• Who will play the role of curator?

Page 14: Embedding Clinical standards in research workshop

Clinical Standards Workshop

The Value Proposition • Not just about short-term data integration• Curating data with ontologies/standards means you can:

– sharing it in ways that are widely understood,– help make it reproducible– Increase possibility of spotting errors, inconsistencies– academics - add possibility of citing your data when someone reuses

• Conflicts with institutional demands• Organisations want results today, possibly tomorrow• Next year is a lifetime away, cycles are mostly <1 year• “For wider adoption, the value proposition has to be that curation with

ontologies and other standards provides value immediately.”

Obvious examples: e.g.Query “Male”

Existing Solutions• Three main categories of solution:

– 1. Fully automated – pure computer science– 2. Fully manual – pure biologist– 3. Hybrid approach – bit of both

Oct 2016

Page 17: Embedding Clinical standards in research workshop

Clinical Standards Workshop

Big Data approaches• Rely on the power of algorithms such as Map-Reduce, NLP or

‘machine learning’ features to align data in some way• Can do a great job at de-duplication and alignment on text

Oct 2016

Page 18: Embedding Clinical standards in research workshop

Clinical Standards Workshop

..But challenges still remain• Postpone, not address, the issue of

applying standards• Develop local ‘schema’, resolves local

integration• Ignores wider integration – pre-competitive

collaboration increasing• Many islands of integration, disconnected

Clinical Standards Workshop

Avoiding Data ‘Parallel Play’• Developmental stage (also

called social coaction) • Playing separately from

others but close to them and sometimes mimicking their actions, but not interacting

• Data, integrated, together, separately from other efforts

Modes of access are important• In our own annotation

software we tested various guises of editing

• Still ended up with spreadsheets

• Familiar modes of access are preferred

• User should be first thought not after thought

• Software should help as much as possible

Future Improvements

Oct 2016

Page 22: Embedding Clinical standards in research workshop

Clinical Standards Workshop

Standards matter, semantics matter

• Aligning on ontologies is not the same as aligning on a word or a number

• The ontology class means something

• You can ask questions• It refers to a model of

knowledge which can be queried

Oct 2016

Page 23: Embedding Clinical standards in research workshop

Clinical Standards Workshop

Standards matter, semantics matter

• Should not be just about supporting import of a format

• Should be about supporting the creation and export using standards

• Future proof: linked data is not going away• COI: FactBio are trying do this

Clinical Standards Workshop

Reward for the data generator• ‘Citation of data’ not high enough reward• Often person generating data, is not beneficiary of post-

experimental curation

They should be– They should be able to ask new questions– Gain new insights– Be offered new recommendations– Impact their understanding– Save time in the short and long term – Benefit now and in future (what I call data prosperity)

Clinical Standards Workshop

Applying standards at each step

• ‘Born semantic’ is best• But otherwise

enabling addition of metadata during each stage also good

• Should become part of each production process step

Oct 2016

Born semantic

Added soon after generation

Added by someone else

soon after

Added months later

Never added

Perfect

Worst case

Average? -

Clinical Standards Workshop

The Ontology Paradox: Access needs to be simple but we need ways of saying complex things

Oct 2016

• Ontologies can describe detailed connections between things

• Annotation is only one step• Context is important• Timelines are important• Editing ontologies is a dark art• We need simpler ways to say

complex things• I call this my ‘professional life

goal’

Page 27: Embedding Clinical standards in research workshop

Clinical Standards Workshop

Semantic Wikis• Seemed like a step in right direction• But are not widely used• I’m not sure I understand why they

have not prospered• Wiki too informal?• No centre of authority (vis a vis

Wikipedia)?• Wikidata gaining some momentum,

though semantics are ‘loose’

Oct 2016

Page 28: Embedding Clinical standards in research workshop

Clinical Standards Workshop

Conclusion – my take homes1. If you don’t use standards (e.g. ontologies)

and focus on local integration you delay sharing and understanding problems

2. Encouraging standards application requires familiar modes of access…

3. …and a reward for data generator to improve value proposition
