Fortune Time Institute: Big Data - Challenges for Smartcity

  1. 1. Big and Open Data Challenges for Smartcity Dr. Victoria López Grupo G-TeC www.tecnologiaUCM.es Universidad Complutense de Madrid August 26th 2014 55 Exchange Place NYC
  2. 2. Big and Open data. Challenges for Smartcity • What about Big Data? • Fighting with Big Data. • Big Data. Big Projects. Privacity. • Open Data. Transparency. Smartcities.
  3. 3. What about Big Data? From Data Warehouse to Big Data (large Data Bases) 3 1970 relational model invented RDBMS declared mainstream till 90s One-size fits all, Elephant vendors- heavily encoded even indexing by B-trees.
  4. 4. What about Big Data? Big Data 3+1+1 V’s 4
  5. 5. Fighting with Big Data 5
  6. 6. Fighting with the Big Data Bioinformatics, Genoma data, DNA, RNA, Proteins and, in general all biological data have been required by computing monitors and storing in large data bases in several laboratories and researching centers along the world The Human Genome Project 6
  7. 7. Customer point of view Looking for flights – Not a simple search 7
  8. 8. Web Issues: Short path 8 Joke but, behind our comfortable position there are some math and programming…
  9. 9. • Restrictions: – Total time – Total Costs – Date/hour • How to sort the results? – http://www.sorting-algorithms.com/ 9 Web issues: Searching & Sorting
  10. 10. How many? 10 Order your room now! One teenager working = one afternoon at home

  12. 12. The solution: organization 12
  13. 13. 13 Big Data: Map Reduce • Created by Google (2004) – Parallel programming model – Simple concept, smart, suitable for multiple applications – Big datasets  multi-node in multiprocessors – Sets of nodes: Clusters or Grids (distributed programming) – Able to process 20 PB per day – Based on Map & Reduce, classical methods in functional programming related to the classic Divide & Conquer – Come from numeric analysis (big matrix products). • Main feature: scalability to many nodes – Scan of 100 TB in 1 node @ 50 MB/sec = 23 days – Scan in a cluster of 1000 nodes = 33 minutes
  14. 14. Big Data: Hadoop, Spark – Used by Yahoo!, Facebook, Twitter Amazon, eBay… – Can be used in different architectures: both clusters (in-house) and grid (Cloudcomputing) https://hadoop.apache.org/ https://spark.apache.org/ 14
  15. 15. How amount of data? 15
  16. 16. Recommender Systems 16 Renew your car insurance – Semantic Web tools – Analysing & storing personal information
  17. 17. Business need to be competitive 17 Harvard Business Review (HBR) blog, CMOs and CIOs Need to Get Along to Make Big Data Work,
  18. 18. Big Data & Business 18
  19. 19. Big Data for Big projects Real Time The Obama 2012 campaign used data analytics and the experimental method to assemble a winning coalition vote by vote. In doing so, it overturned the long dominance of TV advertising in U.S. politics and created something new in the world: a national campaign run like a local ward election, where the interests of individual voters were known and addressed. 19
  20. 20. 20 Big Data for Big projects Real Time How Brazil vs. Germany played out on Twitter Geotagged tweets mentioning key terms around the Word Cup game, July 8, 2014

  22. 22. The close future: Internet of the things 22
  23. 23. Open Data “Open data is data that can be freely used, reused and redistributed by anyone – subject only, at most, to the requirement to attribute and sharealike.” OpenDefinition.org - “Open data is data that can be freely used, reused and redistributed by anyone – subject only, at most, to the requirement to attribute and share alike.” OpenDefinition.org Availability and Access: the data must be available as a whole and at no more than a reasonable reproduction cost, preferably by downloading over the internet. The data must also be available in a convenient and modifiable form. Reuse and Redistribution: the data must be provided under terms that permit reuse and redistribution including the intermixing with other datasets. The data must be machine-readable. Universal Participation: everyone must be able to use, reuse and redistribute – there should be no discrimination against fields of endeavour or against persons or groups. For example, ‘non-commercial’ restrictions that would prevent ‘commercial’ use, or restrictions of use for certain purposes (e.g. only in education), are not allowed. 23
  24. 24. Open Data 24
  25. 25. Why Open Data by Open Knowledge Foundation 25
