I did a short video showing how I create a visual Graph from dbpedia data. In this video I use SPARQL to query a triple-store endpoint, then I take the results, spruce them up in Google Refine and explore the graph in Gephi.
I’ve explored the relationship between members of punk rock bands, but the principle can be applied to any similar dataset.
As part of my job in educational technology, I like to tinker with technology to find solutions to problems. I also like to share these tinkering with friends and colleagues. The way I would previously Read more…
I had a go at creating an animated AI-generated monster through the use of Disco Diffusion and EBSyth. The idea is to take a video of someone who isn’t moving too much as a base Read more…
Recently I came across EbSynth, a program used to convert video footage into a motion painting by painting a single keyframe. I find it interesting that, although AI experts developed the program, it doesn’t do Read more…

hello , i want to expline me your code in R to Create a Graphs used in GEPHI

Hi, I create an adjacent matrix based off two columns and then use R to export that as a graph file. This might not be the best way to do it. I’ll get some examples together for you if I get chance, but I am going to be a bit busy over Christmas

Dear David,
Is it possible for you to upload your R script for further inspection?
Kind regards,
Frederik

This was a long time ago so I’m not sure if I still have it. I will look for you. As far as I remember I just use R to create an adjacency matrix from two columns, band and member name. This might not be the best way to do it. Still, I will look for the script later.

[…] I grabbed the data from the dbpedia endpoint on the web, put it into google refine, exported it to R to turn the data into a matrix then exported it as a graphml file for Gephi. You can see the steps I took in a video I made which lives in this post. […]
