  7. 7. Quantitative Data Competencies• Proxy problems definition – Different problems lead to different questions, which lead to different data sets. Confer acceptability of data source by the definition of the proxy problems.• Key dimensions of variability – Key dimensions were targeted for collection such as time, space, identifier, etc. However, different proxy problems require different key dimensions.• Capturing scope – The following was explicitly captured: • Data structure (E.G. graph relationship data vs. graph transaction data vs. dimensional data) • Data timespan (if time is a dimension) • Data geospatial footprint (if geospatial is a dimension) • Data volume (both in total GB and also in total # of rows) • Determining dataset overlap• Capturing opinions - Current star ratings based on: • Data consistency, volume, and persistence • Data coverage (time and space) • Data precision (time and space) • Data “genuineness” (synthesized data is penalized) • Data distribution (IE: we may have extremely precise geo-spatial data, but if there are only 40 unique geospatial points in the data, the geo-spatial aspects aren‟t that interesting) • Data dimensionality (higher dimensionality with reasonable distributions on each dimension is preferred)

  10. 10. Quantitative Data Competencies Panoramio / Flickr – Metadata on uploaded public photos provides excellent geospatial and temporal resolution, which also provides user information. Estimated 250 million rows of photo metadata with over 150 million already gathered. AIS – Ship tracking data that provides ship „pings‟ as they progress in movement. Precise time and geospatial information provided. 50 million records and counting. OpenStreetMaps – Over 2 billion geospatial points of mapping enthusiasts‟ tracks across the world. Time and userid information also included. Gowalla / Brightkite – About 11 million FourSquare style check-ins with user, location, and time information provided. Example Proxy Problems: • Discovering “Holes” in the data where photos are no longer taken to detect avoided areas • Discovering relationships and links based on co-occurrence between users in time / space • Tracking and analyzing movement patterns on a local and global scale • Analyzing image data for changes in the same locations • Detecting differences in photo activity in an area over time • Detecting events based on abnormal photo activity behavior • Mapping UserIds across data sources to create a unified analytic picture • Detecting home range for each user • Defining patterns of life by routine activities and movement • Tracking language usage in areas to determine abnormal language presence in an area • Local vs tourist movement analysis and extraction • Trending of location popularity UNCLASSIFIED 12
  11. 11. Quantitative Data Competencies Twitter – Sampled ongoing collection of social media tweets with UserId and time. Some even have precise location data, but this is not the norm. Collection pulls roughly between 1-2 million tweets / day. Example Proxy Problems: • Discovery of crowd-sourced phenomena (e.g., people posting to beware of a certain neighborhood) • Discovery of correlated trends (e.g., finding that people posting about a certain topic in an area correlates to higher crime in that area) • Tracking sentiment on certain topics and issues • Tracking language usage in areas to determine abnormal language presence in an area UNCLASSIFIED 13
  12. 12. Quantitative Data Competencies• How can we infer movement patterns from vast amounts of what appears to be just point data collected in time and associated with an identifier (IE: UserId / bank account / etc)?• Technique is applicable to Twitter, FourSquare and MANY other sources Volume plot of photos binned by area on log scale Paris as seen from Flickr over all time 14
  13. 13. Quantitative Data Competencies 1. Goal: to catch active moment between locations a small distance apart 2. Typically two to around a dozen points chained together 3. Located in a small area, but with a definite path through the area 4. Sampled in rapid succession (less than X seconds between points) 5. Thousands or millions of micro-paths make a full path to view Segment ignored: Segment ignored: Velocity too fast Photo taken 120 seconds between points Photo taken Photo taken 2012-08-15 12:35:25 2012-08-15 12:34:59 2012-08-15 12:37:46 Photo taken 2012-08-15 12:37:35 Photo taken 2012-08-15 12:35:11 Person A Common Photo taken path 10 seconds 2012-08-15 12:37:25 Person B 3 seconds pattern A Micropath example forming Person C Overlay thousands / millions of these tiny micropaths together and you get… UNCLASSIFIED 15

  17. 17. Quantitative Data CompetenciesFlickr Paris 2004 changes vs 2005 Hh: [HIGH, high]- an increase between Xt1 -> Xt2 relative to respective (Xt1, Xt2) reference distribution where t1, t2 belong to T. HIGH reflects a strong increase of ones own values (dxi) at location i between t1 and t2 relative to the change of neighboring values (dy). high reflects a modest increase of dy relative to values of dx. Neighbors are defined with the spatially lagged variable Wy, as the eight nearest observations. lL: low, LOW [low, LOW]- a decrease between Xt1 -> Xt2 relative to respective (Xt1, Xt2) reference distribution where t1, t2 belong to T. low reflects a modest decrease of ones own values (dxi) at location i between t1 and t2 relative to the change of neighboring values (dy). LOW reflects a strong decrease of neighboring values of dx. Neighbors are defined with the spatially lagged variable Wy, as the eight nearest observations.Flickr Paris 2011 changes vs 2010 UNCLASSIFIED 19
