(reblogging from post originally published over here)
Today, I have had loads of fun at the Data Innovation Summit in Brussels, Belgium. Hosted in the beautiful Axa Belgium offices, it was a great opportunity to meet 500 (!!) data-minded professionals. I was also able to do an Ignite Talk there, which was quite an experience. 15 seconds for every slide, and no way for you to change the slides yourself and determine the “rythm” – very different. Here are the slides:
But that was not the coolest thing. They also did a “Data Innovation Survey“, which was super cool. The data is all open (find it in this gist), and I of course took it from Excel
//respondents and techniques with PhDs
MATCH (dl:DegreeLevel {name:"PhD"})--(r:Respondent)--(t:Technique)
return dl,r,t
Let’s make it a bit more sophisticated:
//respondents and techniques at level 5 with PhDs and their DegreeFields
MATCH (dl:DegreeLevel {name:"PhD"})--(r:Respondent)-[ht:HAS_TECHNIQUE {level:'5'}]--(t:Techniques),
(r)--(df:DegreeField)
return dl,r,t,df
limit 10
//betweenness centrality of the "DegreeFields"
MATCH p=allShortestPaths((r1:Respondent)-[*]-(r2:Respondent))
WHERE id(r1) < id(r2) and length(p) > 1
UNWIND nodes(p)[1..-1] as n
WITH n, count(*) as betweenness, labels(n) as labels
WHERE "DegreeField" in labels
RETURN n.name, betweenness
order by betweenness desc;
Lovely, thank you Rik
