Talk on community management at Inria fOSSa 2012

The Gephi Consoritium will participate to the fourth edition of the fOSSa Conference taking place from December 4 to 6, 2012 in Lille (France).

The aim of the fOSSa (Free Open Source Academia Conference) is to reaffirm the underlying values of Open Source software: innovation & research in software development.

While the first edition aimed at providing valuable information on the Open Source model at large, the second edition focused specific key-aspects of FOSS such as tech innovation,upcoming issues & challenges in the open development context and how open activities, collaboration and knowledge sharing is beneficial to academia, education & industry. The third edition look at the future of Open Source (Eco system, Trends, new territories, etc).

The fourth edition will address in an open-minded style about:
– Digital Geographic Strategies & the Native Generation,
– FLOSS History with the movie: “Revolution OS” followed by a debate,
– Open Art, collaboration between art & science,
– Licenses in the real life: no lawyers speeches, only facts & return experience,
– Workshops to learn how to develop code for debian, gnome, apache, robotics ROS …
And, of course the usual fOSSa topics (Education & Community management).

At this occasion, Sébastien Heymann will make a presentation about Motivations in Free Software communities, 6th Dec at 2pm in the Community Management track.

“What marks the difference between fOSSa and other events is the air that you breath there. An event organized by passionate people, with passionate attendees as well … and great speakers. Every year you can get some presentations of greater international events in advance (I remember the year of Arduino, to give you an example).” — Gabriele Ruffatti — SpagoWorld Blog 2012.

fOSSa days are open to everyone and registration is free!

Gephi meet-up #4 in Berlin

Information Epidemics with Gephi by Dmitry Paranyushkin / Nodus Labs

Large groups of people can drastically change their opinion, adopt a completely unexpected trend, come out to protest on a square, adopt a certain ideology, have an amazing time at a party, or start using a certain product on mass scale. While all these social phenomena are diverse, one thing in common is that they involve information dissemination that happens in a synchronized way, evoking a certain response from the population at once.

In this workshop I will demonstrate how epidemic theories from network science can be used to study information contagion and trend/rumor propagation (so-called information cascades). We will use real examples from Facebook and Twitter, as well as Gephi software to visualise the sample data.

You will learn what groups to target when planning effective marketing campaigns, how promote your news to the top of the feed on Facebook, generate and seed trends in social networks. You will also find out how information becomes viral and what one can do in order to increase the message’s contagious potential.

The workshop will be held in English and German.

To sign up: workshopinformationepidemics-eorg.eventbrite.com

Date: 16th of February, from 6:00 PM to 8:00 PM
Place: betahaus, 19-20 Prinzessinnenstr (U8: Moritzplatz), 4th floor Arena hall

Gephi meet-up #3 in Berlin

Text Network Analysis with Gephi by Dmitry Paranyushkin / Nodus Labs

In this workshop we will demonstrate a novel method for text network analysis using Gephi graph visualization software. Unlike other topic modelling methods (latent semantic network analysis, LDA) our approach takes into account the structural properties of text network in order to identify the clusters for meaning circulation and the most influential concepts within the text. You will learn how to create graph network representations of texts and perform their comparative quantitive and qualitative analysis. The method can be especially useful for quick text summarization and group sentiment profiling.

What It Can Be Used For:

– Identifying the most influential concepts and topics within a text.
– Comparing different texts together, especially what strategy a text uses to “push” a certain agenda.
– Group sentiment analysis: find the terms that unite any group together
– Quick text summary and overview (can be especially useful for studying or law text)

If you’d like to participate you can send us a short text (200 to 300 words) to info at noduslabs dot com describing your interests and current occupations. We will create text graphs both for participants and the whole group and see how they relate to one another (see the image attached). This may also be useful for you to meet other like-minded individuals at betahaus or find the people who could complement your cognitive map with their knowledge.

To sign up: workshopnoduslabs1.eventbrite.com

Date: 7th of December, Wednesday, 18.00 to 20.00
Place: betahaus, 19-20 Prinzessinnenstr (U8: Moritzplatz), 4th floor Arena hall

We highly recommend you to bring your laptop with you and pre-install Gephi graph visualization software on your computer (works on Mac, PC, Linux).

Next Gephi Workshop at Stanford

Elijah Meeks, digital humanities specialist and Gephi expert (see the video below), will be holding an Intro to Gephi workshop at Stanford University in Meyer Library 220 (also known as the Flex Classroom) at 11AM on Friday, November 11th. The entrance is free.

First Gephi Plugin Developers Workshop on October, 6

This is an announcement for the first Gephi Plugins Developers Workshop October 6, 2011 in Mountain View, California. Come and learn how to write your first Gephi plugin and ask questions. The workshop is organized by Mathieu Bastian, Gephi Architect and will be gratefully hosted by IMVU.

Gephi is a modular software and can be extended with plug-ins. Plug-ins can add new features like layout, filters, metrics, data sources, etc. or modify existing features. Gephi is written in Java so anything that can be used in Java can be packaged as a Gephi plug-in! Visit the Plugins Portal on the wiki and follow the tutorials to get started.

The workshop will start with a presentation of Gephi’s architecture and the different types of plugins that can be written with examples. Details about Gephi’s APIs, code examples and best practices will be presented in an interactive “live coding” way. The Gephi Toolkit will also be covered in details. The second part of the workshop will be dedicated to help individuals with their projects and answer questions.

Some of the best projects using or extending Gephi are developed in the Silicon Valley and we are looking forward helping the developer community. Please don’t hesitate to send us your ideas to maximize efficiency.

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).

Program:

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.

Requirements:

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!
