Program of Netonets 2016 is Out!

As announced in the previous post, the symposium on networks of networks is happening in less than two weeks: May 31st @ 9AM, room Dongkang C of the K-Hotel Seoul, South Korea. Przemek Kazienko, Gregorio D’Agostino and I have a fantastic program and set of speakers to keep you entertained on multilayer, interdependent and multislice networks. Take a look for yourself!

9:00 – 9:15: Room set up
9:15 – 9:30: Welcome from the organizers
9:30 – 10:15: Invited I: Yong-Yeol Ahn: Dynamics of social network of belief networks
10:15 – 11:00: Invited II: Luca Maria Aiello: The Nature of Social Links

11:00 – 11:30: Coffee Break

Session II

11:30 – 12:15: Invited III: Jianxi Gao: Networks of Networks: From Structure to Dynamics
12:15 – 13:00: Invited IV: Tomasz Kajdanowicz: Fusion methods for classification in multiplex networks

13:00 – 14:30: Lunch Break

Session III

14:30 – 15:15: Invited V: Michael Danziger: Beyond interdependent networks
15:15 – 15:35: Contributed I: Bruno Coutinho: Greedy Leaf Removal on Hypergraphs
15:35 – 15:55: Contributed II: Yong Zhuang: Complex Contagions in Clustered Random Multiplex Networks

15:55 – 16:30: Coffee Break

Session IV

16:30 – 17:15: Invited VI: Nitesh Chawla: From complex interactions to networks: the higher-order network representation

17:15 – 18:00: Round table – Open discussion
18:00 – 18:15: Organizers wrap up

Remember to register to the main NetSci conference if you want to attend.

Incidentally, the end of May is going to be a rather busy period for me. Besides co-organizing Netonets and speaking at the main Netsci conference, I’m going to present also at the Core50 conference in Louvain-la-Neuve, Belgium, on the role of social and mobility networks in shaping the economic growth of a country. Thanks to Jean-Charles Delvenne for inviting me!

I hope to see many of you there!

The NetSci Multiple Networks Menu

Friends, scientists, network fanatics, lend me your eyes: I come to announce the program of the Multiple Network Modeling, Analysis and Mining symposium, introduced some months ago on these pages. To give you a quick recap: this is a satellite event which will happen at the 2014 edition of NetSci, a major network science event of the year. The symposium will take place on Monday June 2nd, while the conference itself will start on June 4th and it will last until the end of the week. Differently from last year, we now have space for contributed talks and I like the program we were able to set up. So, I’ll boast about it here.

You can find the overview of the entire event on the official website, but let me give you the highlights.

We have four invited speakers: Frank Schweitzer, Renaud LambiotteNitesh Chawla and Mason Porter. They come from different backgrounds (System Design, Mathematics and Computer Science) which is a great plus for the event. They are going to:

  • Tackle the mathematical foundations of multiple networks;
  • Describe models for multiple networks;
  • Analyse them, both in the flavour of bipartite temporal social networks and in the extension of the classic link prediction problem. Usually in link prediction we are interested in evaluating the likelihood of seeing “a” connection between two nodes. Since in multiple networks there are different types of connections, we are also interested in predicting “which” connection we will observe.

As for the contributed talks, we have a pretty good team, including (but not limited to) works signed by David Lazer from Northeastern University, Juyong Park from KAIST, Eugene Stanley from Boston University and many more. We had such a positive reaction to our call for papers, that we had to increase the slots for contributed talks from 5 to 7 and still reject presentations that we really wanted to see. Among my favourites works there are:

  • Multiple network applications to study the productivity of countries and predicting their growth;
  • The study of evolution of different relations among almost 2000 students from 14 US universities;
  • A network-based approach for ranking the performances of sport teams;
  • Novel way to classify nodes in complex networks where multiple different relations are present;
  • … and more!

For completeness, here’s the detailed schedule, I hope to see many of you there!
