- An interactive Turtle shell
Wouldn’t it be nice to have an interactive environment where you quickly hack together an RDF model and then show it to your clients or colleagues in a more accessible format – i.e. a diagram? Don’t know if there’s anything like that already, but the other day while polishing up the OntosPy library I’ve taken […]
- How to visualize a big taxonomy within a single webpage?
Here’s a couple more experiments aimed at representing visually a large taxonomy. Some time ago I looked at ways to visualise a medium-large taxonomy (3000 terms circa) using one of the many visualisation kits out there. It turned out that pretty much all of them can’t handle that many terms, but there are other strategies […]
- Nature.com subject pages available online!
Subject pages are pages that aggregate content from across nature.com based on the tagging of that content by NPG subject ontology terms. After six months of work on this project we’ve finally launched the first release of the site, which is reachable online at http://www.nature.com/subjects. Hooray! This has been a particularly challenging experience cause I’ve […]
- Creating useful classifications with taxonomies (part 1)
Taxonomies and other classification schemes are omnipresent in Information Architecture. In this post I’ve tried to gather a few ideas on the topic, with the aim of clarifying the issue a little, and maybe help constructing more useful taxonomies. Comments and suggestions are welcome as usual! It recently occurred to me though that there is […]
- Messing around wih D3.js and hierarchical data
These days there are a lot of browser-oriented visualization toolkits, such d3.js or jit.js. They’re great and easy to use, but how much do they scale when used with medium-large or very large datasets? The subject ontology is a quite large (~2500 entities) taxonomical classification developed at Nature Publishing Group in order to classify scientific […]

- Navigating through the people of medieval Scotland… one step at a time
Navigating through the people of medieval Scotland… one step at a time! This is, in a nutshell, what users can do via the Dynamic Connections Cloud application, a prototype tool I’ve been working on recently, in the context of the People of Medieval Scotland project (PoMS), which was launched last week at the University of […]
- DJFacet 0.9.7: MPTT hierarchical facets now supported!
DJFacet is a pluggable module for the Django web application framework that allows you to navigate the data in your webapp using an approach based on ‘facets’. I’ve already written about DJFacet in the past; now the good news is that I’ve released a major update to the software, as now there is complete support […]
