Comparing entropy measures of idea links in design protocols: Linkography entropy measurement and analysis of differently conditioned design sessions

http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=1339952

This paper explores using Shannon's entropy of information to measure linkographs of 12 design sessions that involved six architects in two different experimental conditions. The aim is to find a quantitative tool to interpret the linkographs. This study examines if the differences in the design processes and the design outcomes can be reflected in the entropic interpretations. The results show that the overall entropy of one design condition is slightly higher than the other. Further, there are indications that the change of entropy might reflect design outcomes.

Space Syntax video

My original work was on what is in a field known as 'space syntax'

I'm often asked about space syntax, its hard to track down a good overview, but this is quite a good video giving the urban version of space syntax. You can see some of my software ( and results of my analytic software ) in this video.

This is Alan's talk - its more building centric.

Handy website of the day

I found this a websites from the late 1990's with the original site + anonymised log data.

handy could do with a few more.

hobby research page ranking == degree

Hi - Here is one I came up with to night. I know I've always been quite dismissive of that paper on page ranking ( the kind google does to figure out how to rate things) in the GIS journal as a cheap way to do a naff syntax rip-off with out referencing the social logic of space. I basically assumed that the page ranking algorithm would produce the same kinds of output as integration or at possibly choice (sounds choicy when you here the algorithm). 

I was reading a new book on collective intelligence which explained the google page ranking algorithm and was curious enough to put it into webmap at home.  Doing this I was disappointed to find that page rank correlates well with (0.95) with connectivity / control and very badly integration(0.35)choice(0.77)/movement. 

This might not be true for small world graphs ( which axial maps are not). 

Thought I would include map of Barnsbury for your amusement.
