  3. Measuring Difficulty

  4. Eigenvector Centrality

  5. Metrics

  6. Metrics - Significance

  7. Overview

  8. Stage 1: Data Collection • Openstreetmap • Challenges • Extra data: age, crime, continent, structure, area, population

  9. Merging Roads

  10. Artificial data

  11. Processed Data Inter metric correlations

  12. Discoveries…

  13. Correlation Age

  14. Correlation Age

  15. Correlation Crime I

  16. Correlation Crime II

  17. Continental Boxplots Entropy Gini Coefficient

  18. Stats

  19. Structural Boxplots Entropy Gini Coefficient

  20. Stats

  21. No significant Correlations • Area • Population

  22. Contributions • Model • JIZNA • Applications

  23. 2012 Tag Challenge

  24. Tag Challenge Cities Entropy

  25. More to come Data Dynamic characteristics DARPA’s Red Balloon Challenge

  26. Finally… • Just about three major things • The age of a city can influence the ease of search. • City structure has no significant influence on ease of search. • North American cities easier to search than European/Asian cities.
