Using Google Spreadsheets to extract Google+ friend/follower information for analysis in NodeXL, Gephi

I keep getting this nagging voice in my head to do something with Google+ and Google Spreadsheets. I’ve resisted until now as I don’t think there is enough of an official API there to satisfy my current interest in social network analysis. This hasn’t stopped other people from getting off the beaten track and developing […]

NodeGL: An online interactive viewer for NodeXL graphs uploaded to Google Spreadsheet

Recently Tony (Hirst) tipped me off about a new viewer for Gephi graphs. Developed by Raphaël Velt it uses JavaScript to parse Gephi .gefx files and output the result on a HTML5 canvas. The code for the viewer is on github available under a MIT license if you want to download and remash, I’ve also […]

I used my TAGS template to capture tweets from the #IIE2011 event yesterday. This template includes a summary sheet […]

EDGESExplorer: Simple force layout diagrams from edge lists stored in Google Spreadsheets [NodeXL Gephi]

When I initially pushed TAGSExplorer to the world one of the first reactions I got was from my friend Tony Hirst who suggested having a simple version which let users select two columns to generate a force layout diagram (that’s what I think he was suggesting anyway ;). I’ve played around with other ways to […]

TAGSExplorer: Queryable Twitter archive exploration with Google Visualization API Query Language integration

Since pushing out my Twitter archive visualisation tool, TAGSExplorer, it nice to see people are already pushing out tweets for their own archives. After a full on development period of a couple of weeks, TAGSExplorer is reasonably stable but like most other web services there is some continual tweaking going on behind the scenes. One […]

Sentiment Analysis of tweets: Comparison of ViralHeat and Text-Processing Sentiment APIs

Turning Google+1’s (Plus Ones) into Tweets (re-enabling my share workflow in Google Reader)

Would it surprise you that since I’ve fallen out with Google Reader, we’re on a trail separation (I’m having a fling with Tiny Tiny RSS) that we’re back together again. We’ve got some new ground rules though, the main one being when I Google +1 a news item it should also hit my Twitter feed. […]
