Workshop: Text Network Analysis With GEPHI

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.

In this workshop Dmitry Paranyushkin 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).

Working for Lufthansa back in 2002, Joachim (CEO & founder @ Jolocom) had the idea to develop a better system for companies to swap data internally and for people to share their data with companies. Back in 2002, the resistance to open networks and communication was strong. However, just a few years later, social media and blockchain changed the rules of the game, which led to the founding of Jolocom in 2014. (Read the whole story here

Ellie joined the Jolocom team in the fall last year. She’s part of the content team and is responsible for communications and online platforms maintenance. 

Volker is currently studying IT-Systems Engineering at HPI, working on his master thesis with Jolocom. He joined the software development team in March this year and has previously worked from betahaus for another startup company.

With two locations in the heart of the city, betahaus l Sofia is a home of some of the most successful Bulgarian startups and is one of the leading innovation hubs in Sofia. Their main space is located just two minutes on foot from Sofia University and the second one stands right at the central Slaveykov Sqaure and has a beautiful view over the city.

As all of our locations, its pet and bicycle friendly and offers the same comfy and relaxed atmosphere you've come to expect from betahaus. Identical to our space, betahaus | Sofia uses glass doors for its team rooms, to build transparency and inclusion.

betahaus | Sofia is spread across 1800 q.m. divided into 2 separate spaces. Shipka 6 is 1300qm and takes over the entire 3rd floor of the UBA – Union of the Bulgarian Artists. Slaveykov Square is placed on the roof top of another historical building in Sofia. There they have two balconies with 360 degrees view, a cafe/bar and a shared kitchen.

Membership plans start from 350,– BGN for Workspace and go up to 435,– BGN for Private Offices. Currently, the space has around 190 members and will soon implement also Club Memberships plan. Every member of the Club will have access to events, conference room and betahaus community.

Ellie: Currently we have around 5 active pilots and we effectively work B2B2C. So we build our application for businesses which have their own user bases.

Volker: One of our ongoing projects is a pilot with Telekom. With their team, and partners from Riddle & Code and Simple Mobility, we have created the Magenta Scooter — an innovation in e-mobility that allows users to ride share while using their decentralized digital IDs. That means users can rent the scooter with our app and our identity. The main advantage there is that you can store your drivers licence in your Jolocom SmartWallet and then share this license with the app of Telekom. This eliminates the long onboarding process of verifying your license. 

Ellie: Another example is our e-government collaboration with The City of Antwerp called Blockchain on the Move. Using the SmartWallet, municipal employees can issue and validate their own credentials and create eIDs for citizens – it’s a digital ID with which you can register at the university or go to a swimming pool, as two examples.

Ellie: Two years ago we adopted a new legal structure for Jolocom GmbH according to the purpose model of ownership, manifesting our commitment and dedication to building a self-sovereign organization. That means we can’t take VC funding or sell public shares of the company. 

Volker: Jolocom is a community driven organisation – both in a tech sense but also much further beyond. We’re hugely involved in the DWeb community where we organize and attend events for the decentralized community. Every year we also help organize and attend the DWeb Camp in San Francisco, which brings together all kinds of creatives so this technology of tomorrow is built in a collaborative way.


Ellie: I know that before joining betahaus Jolocom was in the Ethereum office – a collaborative blockchain space for companies also building on the same platform and the idea was always to stay within a coworking space. When they closed and we had to move, the next closest choice in terms of company culture was betahaus. 

Ellie: The people in the building and the spaces are just really cool. I personally don’t go to community events as much as i would like to but I still end up meeting a lot of people here. Mostly in the kitchen. One of my good friends is actually someone I met in betahaus. 

Volker: I once saw a friend of mine presenting at betabreakfast and I didn’t know that he would be here. It was so funny seeing him on the stage.

Volker: There is this really nice place, called Green Rabbit with salads and baked potatoes where I like to go to. Sometimes I just keep it simple and go to Lidl.

Ellie: I eat a lot in west.berlin cafe which is here around the corner and I love the Matcha Lattes from Starbucks.
