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…

How manydimensions?

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

How manydimensions?

Q:
So where might we findNETWORK GRAPHSdefined?

Tools…

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

Data format can be key
“Key”, by dewitt

3
How is it formatted?

4
“Writing diagrams”

Graphviz

What do you wantto learn from it?

How canvisual(isation)s help?

Just remember this:what stories- are you hoping to discover?- are you trying to tell?

I hope that’s beenouseful.info….?
