Parallel Force Atlas
Hi everybody! As mentioned in a previous post, I have been working on a parallel implementation of the Force Atlas layout recently and a first version is ready for release. I published it earlier today and it will hopefully be available quite soon. I attached the plugin NBM if anybody wants to try i...

Re: Best Layout Algorithm for Massive Newtork
I planned to write about that a little later but since you are talking multi-core, I’ll say it here. I have recently implemented a multi-core version of the Force Atlas layout in Fortran using OpenMP for the parallelism. Since the repulsion in O(n2) is where most of the time is spent, I wrote a smal...

Re: In/Out Degree
You are correct about the definitions of In Degree and Out Degree. When running the In/Out Degree statistic, these two metrics are calculated for each node of the graph and displayed in the Data Laboratory and the Edit panel. The AvgInDegree and AvgOutDegree shown in the statisctic report are identi...

Re: In/Out Degree
If you are talking about the Average In Degree and Average Out Degree calculated with the In/Out Degree statistic, it is normal to find identical values. They are calculated by summing the in degree (or out degree) value of each node that make the graph and dividing the final sum by the number of no...

Here is another interesting graph: Package Dependency graph of Gephi's trunk with the node size linked to the number of bugs detected by FindBugs (http://findbugs.sourceforge.net). package.png Regarding the types of bugs, most of them belong to the Style and Performance categories. The winner packag...

Re: Source Code Visualization Plug-in
At the beginning, I wanted my research project to focus on repositories and I had looked around for existing APIs. SVNKit (http://svnkit.com/) is a good example for SVN

Re: Source Code Visualization Plug-in
My plugin is not devoted to study repositories, it is only a small feature I included. So we only have a small overlap and I think that merging is not really an option right now. But when your plugin will be mature enough to be released, I will definitely take advantage of it in my own plugin. I sti...

Re: Source Code Visualization Plug-in
Very nice work Nellistos! It's a funny coincidence that you bring that idea right now. As part of the Software Visualization Plug-in that I am currently writing, I have also added the functionality to import data from SVN and Bazaar log files. I associate to each file in the repository the last deve...

Re: AlchemyAPI Semantic Analysis Plugin
This is a very interesting plugin, thank you for sharing it. I tried it out on a couple of web pages and it gives very nice results. It would be even more interesting if a weight was assigned to each node (based on the frequency of the word in the text for example) so that we could rank the nodes us...

Re: Source Code Visualization Plug-in
It is normal that you were not able to run dependency finder. Until yesterday I had not figured out how to run the jar files (of the command-line tools) included into the plugin. Thus you had to install each tool manually at a specific location (I was basically the only one who could use the plugin ...
