Scraperwiki Powered OpenLearn Searches – Learning Outcomes and Glossary Items

A quick follow up to Tinkering With Scraperwiki – The Bottom Line, OpenCorporates Reconciliation and the Google Viz API demonstrating how to reuse that pattern (a little more tinkering is required to fully generalise it, but that’ll probably have to wait until after the Easter wifi-free family tour… I also need to do a demo … Continue reading “Scraperwiki Powered OpenLearn Searches – Learning Outcomes and Glossary Items”

My ILI2012 Presentation – Derived Products from OpenLearn/OU XML Documents

FWIW, a copy of the slides I used in my ILI2012 presentation earlier this week – Making the most of structured content:data products from OpenLearn XML: I guess this counts as a dissemination activity for my related eSTEeM project on course related custom search engines, since the work(?!) sort of evolved out of that idea… … Continue reading “My ILI2012 Presentation – Derived Products from OpenLearn/OU XML Documents”

Viewing OpenLearn Mindmaps Using d3.js

In a comment on Generating OpenLearn Navigation Mindmaps Automagically, Pete Mitton hinted that the d3.js tree layout example might be worth looking at as a way of visualising hierarchical OpenLearn mindmaps/navigation layouts. It just so happens that there is a networkx utility that can publish a tree structure represented as a networkx directed graph in … Continue reading “Viewing OpenLearn Mindmaps Using d3.js”

Generating OpenLearn Navigation Mindmaps Automagically

I’ve posted before about using mindmaps as a navigation surface for course materials, or as way of bootstrapping the generation of user annotatable mindmaps around course topics or study weeks. The OU’s XML document format that underpins OU course materials, including the free course units that appear on OpenLearn, makes for easy automated generation of … Continue reading “Generating OpenLearn Navigation Mindmaps Automagically”

Asset Stripping OpenLearn – Images

A long time ago, I tinkered with various ways of disaggregating OpenLearn course units into various components – images, audio files, videos, etc. (OpenLearn_XML Asset stripper (long since rotted)). Over the last few weeks, I’ve returned to the idea, using Scraperwiki to trash through the OpenLearn XML (and RSS) in order to build collections out … Continue reading “Asset Stripping OpenLearn – Images”

Tinkering With Scraperwiki – The Bottom Line, OpenCorporates Reconciliation and the Google Viz API

Having got to grips with adding a basic sortable table view to a Scraperwiki view using the Google Chart Tools (Exporting and Displaying Scraperwiki Datasets Using the Google Visualisation API), I thought I’d have a look at wiring in an interactive dashboard control. You can see the result at BBC Bottom Line programme explorer: The … Continue reading “Tinkering With Scraperwiki – The Bottom Line, OpenCorporates Reconciliation and the Google Viz API”

Exporting and Displaying Scraperwiki Datasets Using the Google Visualisation API

In Visualising Networks in Gephi via a Scraperwiki Exported GEXF File I gave an example of how we can publish arbitrary serialised output file formats from Scraperwiki using the GEXF XML file format as a specific example. Of more general use, however, may be the ability to export Scraperwiki data using the Google visualisation API … Continue reading “Exporting and Displaying Scraperwiki Datasets Using the Google Visualisation API”

Visualising Networks in Gephi via a Scraperwiki Exported GEXF File

How do you visualise data scraped from the web using Scraperwiki as a network using a graph visualisation tool such as Gephi? One way is to import the a two-dimensional data table (i.e. a CSV file) exported from Scraperwiki into Gephi using the Data Explorer, but at times this can be a little fiddly and … Continue reading “Visualising Networks in Gephi via a Scraperwiki Exported GEXF File”

Deconstructing OpenLearn Units – Glossary Items, Learning Outcomes and Image Search

It turns out that part of the grief I encountered here in trying to access OpenLearn XML content was easily resolved (check the comments: mechanise did the trick…), though I’ve still to try to sort out a workaround for accessing OpenLearn images (a problem described here)), but at least now I have another stepping stone: … Continue reading “Deconstructing OpenLearn Units – Glossary Items, Learning Outcomes and Image Search”

A Tracking Inspired Hack That Breaks the Web…? Naughty OpenLearn…

So it’s not just me who wonders Why Open Data Sucks Right Now and comes to this conclusion: What will make open data better? What will make it usable and useful? What will push people to care about the open data they produce? SOMEONE USING IT! Simply that. If we start using the data, we … Continue reading “A Tracking Inspired Hack That Breaks the Web…?
