First Gephi meet-up in Berlin

user-group_smallThis is an announcement for the first Gephi User Group meet-up in Berlin! The area has many active Gephi users and supporters and we are looking forward making regular meetups, to create connections and discuss features and projects. The group is also open to students interested in open-source or data visualization.

date2 The first event is planned for Thursday September 8, 17.30 to 19.30 (free access) in betahaus, 4th floor (Arena), Prinzessinnenstr 19-20, 10999, Berlin (map).

In this workshop conducted by Dmitry Paranyushkin from Nodus Labs hosted at Berlin’s most important co-working hub betahaus, we will demonstrate how one can visualize and analyze a social network or a community (using an example from Facebook selected by the participants). We will find out how to identify the most influential nodes within a network, various subgroups within a community, and the most efficient communication strategies to spread information within a group.

We will also discuss what behavior within the network fosters stronger ties between the members and a more sustainable community.

This event will also be first event of the Gephi Meetup Group in Berlin and we can move to betahaus cafe after to discuss further questions after the workshop.



Dmitry Paranyushkin is a professional amateur who’s had numerous affairs in the fields of arts, music, intersubjective relations, network research and internet business. He’s the founder of ThisIsLike.Com – an online mnenomic network and Nodus Labs – an exploratorium of ideas in the fields of network analysis. Having fled Russia for undefined reasons in 1976 he’s found a temporary refuge in Berlin where he lives in a castle on Spree river and occasionally visits betahaus to steal rocket-fast broadband frequencies.

Data in sight – hackathon in San Francisco

Creative Commons, the Netherlands Office for Science and Technology and Swissnex San Francisco is organizing a weekend hackathon about data visualization in which Mathieu Bastian will give a demo of Gephi. The event is called “data in sight: making the transparent visual“, and runs June 24-26 at Adobe in SOMA (in San Francisco).

Join us for data in sight: making the transparent visual, a hands-on data visualization competition held June 25th and 26th, 2011, at the Adobe Systems, Inc. offices in San Francisco’s SoMa District. Open to coders, programmers, developers, designers, scientists, members of the media—anyone who believes that data is divine and has ideas for bringing it to life.

During the hackaton, Mathieu will help teams to code Gephi plug-ins or mashups. Ideas go from live data streaming to layouts, filters or web widgets. If you have ideas, please come to the forum to open a discussion.

Gephi Tutorials at UKSNA and ICWSM 2011

We are very excited to announce that the Gephi Team has a tutorial session at both UKSNA and ICWSM conferences this summer!

UKSNA will be located at the University of Greenwich, London. The Gephi Short Course is on Wednesday, 6 July (2:30 – 6:30PM).
The UK Social Networks Conference offers an interdisciplinary venue for social and behavioral scientists, sociologists, educationalists, political scientists, mathematicians, computer scientists, physicists, practitioners and others to present their work in the area of social networks. The primary objective of the conference is to facilitate interactions between the many different disciplines interested in network analysis.

ICWSM Tutorial Day will be held July 17, 2011 (1:00 – 4:00 PM) in Barcelona, Spain.
The International Conference on Weblogs and Social Media is a unique forum that brings together researchers from the disciplines in computer science, linguistics, communication, and the social sciences. The broad goal of ICWSM is to increase understanding of social media in all its incarnations.

Registration to these events is still open! The tutorial at ICWSM costs $150 ($100 for students). The tutorial at UKSNA costs £100 (£50 for students).


In these tutorials, Sébastien Heymann and Julian Bilcke will provide a hands-on demonstration of the essential functionalities of Gephi, based on a real case scenario. The participants will be guided step by step through the complete chain of representation, manipulation, layout, analysis and aesthetics refinements. Particular focus will be put on filters and metrics for the creation of their first visualizations. They will be incited to compare the hypotheses suggested by their own explorations. They finally will walk away with the practical knowledge enabling them to use Gephi for their own projects. The tutorial is intended for professionals, researchers and graduates who wish to learn how playing during a network exploration can speed up their studies.


Participants should come with their own laptop (and a mouse!) with Gephi installed. After the guided introduction, they will have time to work on a dataset of their own and receive help and direct feedback from the teaching team.

It is also a great opportunity to meet researchers and practitioners interested in network visualization, looking forward speaking with you all there!

First Gephi meetup in SF Bay Area

This is an announcement for the first Gephi User Group meetup in San Francisco Bay Area! The area has many active Gephi users and supporters and we are looking forward making regular meetups, to create connections and discuss features and projects. The group is also open to students interested in open-source or data visualization.

The first event is planned for Thursday May 12 in San Francisco. The ambiance will be informal and relaxed, to facilitate contacts and discussions.

Gephi can be used in many domains and with different types of data. Whether you are a scientist, a student, an artist, a developer or a simple enthusiast, you are welcome to join the community and show up at our meetup. It’s a great opportunity to ask questions, discuss data, plugins, code, metrics or visualization.

The meetup will be organized by Mathieu Bastian, Gephi co-founder. To register, sign-in on and RSVP for the event.

Gephi maps exhibited at the International Design Biennale

affiche_last2-187x300 The Saint Étienne International Design Biennial, holding from 20 November to 5 December, is a unique event in the domain of design, due to the exhibitions shown as well as the diversity of its attendees. The Biennial democratizes design and makes it accessible to all kinds of audiences, proving that this creative discipline can take many forms, and is often driven by human aspects, including its uses by humans.

The theme of the 2010 biennial is around teleportation. It intends to explore paths of discoveries that will tend in their extreme expression to lead to a possible teleportation as the dematerialization of movement which appears to be an incredibly revealing notion of our era.

Sebastien Heymann will exhibit maps of designers’ conceptual world, placed at the center of the “Prédiction” exhibition. Made in collaboration with Benjamin Loyauté, curator of the event, these inscriptions are a proposal to reveal the state of knowledge sharing in Design today.

Useful information on how to come here.


You may contact Sebastien by email to appoint a meeting during the first weekend.

Ten free tickets will be given to the first comments of this post!

Gephi wins Duke’s Choice Award 2010

The Duke’s Choice Awards recognize and honor extreme innovation in the world of Java technology, and are granted to the most innovative uses of the Java platform. Because the primary judging criteria is innovation, the awards put even small developer shops on an equal footing with multinational giants. The winners are selected by Oracle’s Java technology leadership team.

Congratulations to all Gephi contributors! Thank you to the Oracle’s Java Team to make Gephi a Duke’s Choice and the technology that have enabled us to build Gephi and Gephi Toolkit.

The winners will be featured at the JavaOne Conference in San Francisco, September 19-23rd. Gephi’s Software Architect, Mathieu Bastian will be present there to receive the award, and attend the conference!

Java provides all the components and development tools to develop large data-intensive open-source applications. Gephi is built on top of the Netbeans Platform, and profit from its module and window systems. The platform allows us to propose solutions to reuse and extend features, in terms of plug-ins, and let developers create new data wrappers, algorithms or filters easily. The rendering engine is built with JOGL (Java OpenGL) and gives responsiveness and interactivity, thanks to hardware acceleration. We use a large number of Java libraries. I would like to use the occasion to offer thanks to all contributors of these projects.
