This is NOT a presentation about:
0 What data is there?
AEIOU – Aberystwyth University – aggregated repository activity data Agtivity– University of Manchester – usage data from Advanced Video Conferencing services users Exposing VLE Data – University of Cambridge – activity and attention data for Cambridge’s institutional virtual learning environment Library Impact Data – Huddersfield University – prove a statistically significant correlation between library usage and student attainment RISE – Open University – use attention data recorded by EZProxy to provide recommendations to users of the EBSCO Discovery search solution. Salt – University of Manchester – using 10 years of library circulation data to support long tail discovery Shared OpenURL Data – EDINA – open OpenURL data STAR-Trak– Leeds Metropolitan University – highlight and manage interventions with students who are at risk of dropping out UCIAD – Open University – investigate the use of semantic technologies for integrating user activity data from different systems
Some example visualisation types…
Q: So what might aTREEMAPbe good for?
aka “seasonal subseries”
Q: So what might aCYCLE PLOTbe good for?
gnuplot Use white space
Q: What else dotime series hide?
matplotlib Trends #time series data in d #first difference fd=np.diff(d) Autocorrelation
Q: So where might we findNETWORK GRAPHSdefined?
Data Application Output Data [Code] Output
Tools can also be appropriated…
Things to remember…
Data has “shape” “Shape Sorter”, by Ella’s Dad
1 What size/shape/state is it in…?
Big text file..?…ask your nearest Unix sysadmin for help http://blog.ouseful.info/2011/06/03/postcards-from-a-text-processing-excursion/ http://bit.ly/lOVySX
2 How is it structured?
Bulk properties andsimple manipulations Number of rows containing x Structural ordering (sort by column) …again, ask your nearest Unix sysadmin for help
