Hello Pierre,
Thank you for informing us about your research as well as workshop itself. 
Question - will the presentations from the workshop available online (pdf, 
video)? Would love (and I guess not only me) to watch it.
Best,Michal.

#DigiRevCMI New Information Technology Tools in 21st Century

My presention yesterday was the opportunity to review that last major  
OpenSteetMap / HOT Responses in the context of disaster and to show the various 
management aspects of such interventions plus quality problems / management in 
the context of such 
responses.https://twitter.com/pierzen/status/661120335845138432

I presented briefly the Semantic analysis I started of the 2015 Nepal response. 
Looking at the OSM Planet File for 2015-04-24 (before the Response) and 
2015-06-07 (After the response), I measured how the objects are related to OSM 
features. This important measure of quality, completes other quality measures 
of OSM data. It also gives us a global measure of quality, and can help us 
monitor the progression of the crowdsource effort and detect rapidly some 
tagging problems. The first step is to relate parents / childs (ie. relation, 
way, node) and find the tags that describe each OSM Feature.

Either before or after the Nepal Response, only 1% of the objects cannot be 
related to a feature such as highway, building, amenity, etc.  No key / value 
combination listed on the OSM Map Features wiki page (plus specific HOT 
disaster keys).  A 1% error shows a high ontologic precision of the data 
produced.  Data with no feature, is Invisible data. Either, there was syntax 
error in the key / value, no tag, or a contributor simply added a name or note. 
We need to look more closely at such patterns and find ways to correct them 
rapidly.
To show how we can focus on this "Invisible Data" and cure it, I created the 
JOSM NoFeature Mappaint style. It can be selected from the JOSM Mappaint 
Preferences. https://josm.openstreetmap.de/wiki/Styles/NoFeature. This Style 
shows the key-value combinations I selected for my OSM data analysis.  I invite 
HOT Validators to use this style and test it while validating data.

We also have access to  dynamic data (ie data created, modified, deleted).  I 
will analyze more in detail and try to identify patterns. Monitoring semantic 
quality of data produced can help to correct rapidly, revise instructions, etc.

This two day workshop is a great opportunity to discuss with other Digital 
Humanitarian Network contributors and thanks to Per Aarvik from SBTF and Bergen 
Universiy who organized this workshop.
