GSoC 2009 student interview

8 March 2010

Community ~

Today I am pleased to interview Helder Suzuki, Gephi student at Google Summer of Code 2009.

Helder is a Computer Engineer student at Instituto Tecnológico de Aeronáutica and participated as a student in the 2009 Google Summer of Code. He’s currently working as a Software Engineer Intern at Google in Mountain View, California.

 

Sebastien Heymann: Hi Helder Suzuki, you took part in Gephi with the Google Summer of Code 2009 (GSoC), by handling the layout module and implementing the Yifan Hu’s multi-level algorithm. Could you explain why you chose this project, in particular why getting involved in Gephi although there are such great other organizations like Debian, WordPress or Mozilla?
Helder Suzuki: I really believe in the power of graphs application in variety of problems, this is a very hot topic and it’s gaining a lot of momentum in the research community and in the industry. My previous research was related to graphs, so I had some experience in the area already, it made a lot of sense for me to apply for Gephi.

* interaction: Highlight neighbors and interact directly with the visualization when using tools.
* partitionning: Use data attributes to colorize partitions and communities.
* ranking: Use degree, metrics or data attributes to set nodes/edges’ color and size.
* metrics: Run various algorithm in one click and get HTML report page.
* data laboratory: Data table view with search feature.
* dynamics: Use Timeline to explore dynamic graphs.
* filtering: Dynamic queries, create and combine a large set of filters.
* auto update: The application is updating itself it’s core and plugins.

Gephi 0.7alpha2 released

18 February 2010

Announcement Events Uncategorized ~

Gephi 0.7 alpha2 was just released. It increases stability and fix issues that were reported on our forum and bug tracker. Thanks for your valuable feedbacks!

Normally, for minor versions like those, Gephi updates itself by asking users to update when Gephi starts. This AutoUpdate feature was not yet available for 0.7alpha but is working now. Therefore users need to download this new 0.7alpha2 version to profit for upcoming updates through the plugin center.

Check releases notes and download latest version. Please uninstall previous versions first before installing it.

One can find many network and graph datasets on this wiki page.
