Powering question driven problem solving to
improve the chances of finding new medicines

Science
(+Business)
Most hypotheses are not
going to make it

3.
Aspirations of scientific knowledge management
1) Persistence
– Efficient organization.
– The hypotheses that we validate/invalidate today need to be
revisited by the next generation of scientists.
2) Vigilance
– Effective organization.
– Without access to the right data and prior knowledge at the right
time, we risk making very costly, avoidable business decisions.
Andrew Witty,
GSK CEO 2008-2017

Inconsistent use of language at source =
Serious downstream problems
SDS
– Serine dehydratase
– Sodium dodecyl sulfate
– Shwachman–Diamond syndrome
– Safety data sheet
GSK
– GlaxoSmithKline
– Glycogen synthase kinase

5.
Data & knowledge capture forms:
Regulatory in purpose but what about
reward in design?

6.
All Pharma motivation: Acquire knowledge to assert
confidence in core types of evidence

7.
Self-learning questionnaires: Concept
“Auto-suggest” metadata tagging [AUTHOR
ACTION] & auto literature evidence searching
[AUTHOR REWARD] to improve language
consistency1 at source and findability2 of
reported evidence [OUTCOME]
1Great for improving search engines
2Great for making scientists effective

8.
Application of state-of-the-art
algorithms:
What’s possible now?
vs
What will be possible with expert-
curated data over the next few
years?

Examples
1. Determine from the context of the sentence whether author meant
“GlaxoSmithKline” or “Glycogen Synthase Kinase” when he/she
wrote “GSK”
2. Classify and present sentences (+link to documents) with most
similar metadata content to expected answers
3. Recommend predominant synonyms being used by individual
departments e.g. is a particular department really working on
“Glycogen Synthase Kinase” and using the synonym “GSK”?
4. If a significant efficacy or safety event is reported in a “Clinical”
questionnaire, automatically alert the author whether the
outcome/risk was predicted earlier in a “Pre-clinical”
questionnaire.

10.
Scoring “everything” – does it make sense to do it now or once
we actually have enough labelled training sets?
e.g. email spam
filtering

Pilot work

12.
1. Found evidence from rare
disease clinical trial missed by
project team
2. Found mechanistic hypothesis
that a program team had not
considered
3. Identified plausible mechanism
for lab observation
Impact

13.
• It’s all about the questions
• Technology can help
overcome cultural challenges
• Persistence and patience key
