Why we need metrics

Published on

What is the value of an opened dataset? The value depends on a series of elements, both intrinsic and extrinsic. The quality of the dataset is something we usually measure, the intrest of a dataset is something we measure, but we can't measure the ecosystem value of a given dataset.

Transcript of "Why we need metrics"

  1. 1. Why do we need Metrics? (and what metrics do we need?) Marco Montanari (@ingmmo, marco.montanari@gmail.com), OpenGLAM WG
  2. 2. Who am I? š @ingmmo (twitter) š marco.montanari (facebook, gmail) š ingmmo.com š OpenGLAM workgroup representative for Italy š Developer š Art/Design/Architecture freak
  3. 3. A question for you…
  4. 4. The big question Do we know the impact the opened data has on Economy?
  5. 5. The classics š Usage metrics š Visualization metrics š Reuse metrics š Download metrics š Cool!!! š Do these infos represent the real impact or the real value of the datasets?
  6. 6. Rethinking metrics
  7. 7. A new model for Data Metrics The dimensions on which we can work on this model can be š Spatial (do neighbours have a dataset?) š Topic-driven (do we talk about the same stuff?) š Time-bound (do we have a history about that data?)
  8. 8. A new model for Data Metrics - Space Cool! Very Uncool L
  9. 9. A new model for Data Metrics - Time Time series (EuroStat, ISTAT, National Statistics agencies) J Anyone else? L Municipalities have lots of historical data!
  10. 10. A new model for Data Metrics - Topic š Ontologies! à We have lots of people working on them!! š We have ENORMOUS amounts of CSVs… š Can we give semantics to everything? SURE!!
  11. 11. Wait that’s cool for anything BUT GLAM Data
  12. 12. Let’s see Guernica… š  Spatial information: š  Guernica is about Guernica (Location) š  Guernica is in Madrid (Location) š  Guernica was painted in Paris (Location) š  Time information: š  Guernica was painted in 1937 š  Guernica was exposed at the MoMA until September 1981 š  Guernica was exposed at the Casón del Buen Retiro until 1992 š  Guernica is exposed at the Museo Reina Sofía š  Topic Information: š  Guernica is about War, pain, š  Guernica is about Guernica (Location) š  Guernica is about The bombing of Guernica (Event in space and time) š  Guernica is enormously complex: http://en.wikipedia.org/wiki/Guernica_(painting)#The_painting
  13. 13. So now what? š  We now have the three dimensions. Are they enough? Are they too much? š  Europeana: has all of them (in part) [depending on the availability of the single institutions] š  City of Chicago: Has all of them and they are pretty well structured [lots of id columns enabling foreing keys] š  Most datasets: L
  14. 14. Let’s discuss this!!! Thanks, by the way!
