KNOWLEDGE ARCHITECTURE: IT’S
IMPORTANCE TO AN ORGANIZATION
Combining Strategy, Data Science and
Information Architecture to Transform Data to
Knowledge
David Meza
Chief Knowledge Architect

2. AGENDA
• Why Connected Data
• Knowledge Architecture
• Opportunities
• Questions?

5. “The most important contribution
management needs to make in the
21st Century is to increase the
productivity of knowledge work and the
knowledge worker.”
PETER F. DRUCKER, 1999

6. NASA Challenges
• Hundreds of millions of documents, reports, project data, lessons learned,
scientific research, medical analysis, geo spatial data, IT logs, etc., are
stored nation wide
• The data is growing in terms of variety, velocity, volume, value and veracity
• Accessibility to Engineering data sources
• Visibility is limited

7. To convert data to knowledge a convergence of Knowledge
Management, Information Architecture and Data Science is
necessary.

8. Knowledge Architecture
• The people, processes, and technology of designing, implementing, and
applying the intellectual infrastructure of organizations.
• What is an intellectual infrastructure?
• The set of activities to create, capture, organize, analyze, visualize,
present, and utilize the information part of the information age..
• Information + Contexts = Knowledge
• Information Architecture + Knowledge Management + Data Science =
Knowledge Architecture
• KM without applications is empty (Strategy Only)
• Applications without KA are blind (IT based KM)
• Data Science transforms your data to knowledge

9. “We have an opportunity for everyone in the world to have access to all the world’s
information. This has never before been possible. Why is ubiquitous information so
profound? It is a tremendous equalizer. Information is power.”
ERIC SCHMIDT (FORMER CEO OF GOOGLE)

11. Areas of Opportunity
11
• Search
• Storage
• Data Driven Visualization

of total R&D spend is
wasted duplicating
research and work
previously done.

of decisions are made
with incomplete,
inconsistent and
inadequate information

Workers can’t find the
information they need
almost half the time.

What We
Are Looking
For

15. NASA SEARCH EVALUATION
15
• There is No One Solution
• Master Data Management Plan is essential
• Identify Critical Data
• Develop Standards for Government and Contractor created data
• Analytics is essential
• Meta Data

16. TOP USER REQUIREMENTS
16
• Semantic search
• Cognitive Computing – Clustering, topic modeling
• Faceting
• Repository specific searches
• Ability to save searches
• Alerts

17. There was a sad engineer…

19. Repository Specific
Clustering
Save, Alerts
Facet Filter

22. Opportunity 2: Storage and Access

23. Document to Graph

25. There was a inquisitive engineer…

26. LESSON LEARNED DATABASE
26
2031 lessons submitted across NASA. Filter by date and Center only.
Useful information stored in database.

27. TOPIC MODELING
27
Topic models are based upon the idea that documents are mixtures of topics, where a
topic is a probability distribution over words.
LDA Model from Blei (2011)

WHAT COULD YOU ACCOMPLISH IF YOU COULD:
• Empower faster and more informed decision-making
• Leverage lessons of the past to minimize waste,
rework, re-invention and redundancy
• Reduce the learning curve for new employees
• Enhance and extend existing content and document
management systems
