Netonets @ Netsci17: Program

As previously announced, this year’s edition of the Netonets event will happen again as a satellite of NetSci. The conference will take place in Indianapolis. The general program of the conference can be found here: http://netsci2017.net/program. I will be there, hosting the satellite just like last year. It will take place Tuesday, June 20th and it will run for the entire day.

We have just completed a tentative program. We are going to have four great invited speakers: Marta C. Gonzales, Romualdo Pastor-Satorras, Gareth Baxter and Paul Hines. We also have five contributed talks. You can find the first draft of the program down here, subject to change in case of conflicting schedules for any of the participants. I will keep up to date in case that happens.

Netonets @ NetSci 2017: Call for Contributions!

We are delighted to invite submissions for

Network of Networks
7th Edition – Satellite Symposium at NetSci2017

taking place in JW Marriott Indianapolis, Indiana, United States,
on June 20th, 2017.

We invite you to submit a 300 word abstract including one descriptive figure using our EasyChair submission link:

Deadline for submission: April 21st, 2017.
Notification of acceptance will be sent out by April 28th, 2017.

Further Information at: http://www.netonets.org/events/netonets2017

For the seventh time, it is our pleasure to bring together pioneer work in the study of networks of networks. Networks of networks are networks in which the nodes may be connected through different relations, are part of interdependent layers and connected by higher order dynamics. They can represent multifaceted social interactions, critical infrastructure and complex relational data structures. In our call, we are looking for a diversity of research contributions revolving around networks of networks of any kind: in social media, in infrastructure, in culture. We are particularly keen in receiving works raising novel issues and provocative queries in the investigation of networks of networks, as well as new contributions tackling these challenges. How do networks of networks change the paradigm of established problems like percolation or community detection? How are we shifting our thoughts to be ready for this evolution? Running parallel to NetSci, the top network science conference, this event provides a valuable opportunity to connect with leading researchers in complex network science.

Confirmed Keynote:

Marta Gonzales – MIT
Gareth Baxter – University of Aveiro
Romualdo Pastor-Satorras – Universitat Politècnica de Catalunya
Paul Hines – University of Vermont (UNCONFIRMED)

The final program will strive for the inclusion of contributions from different research fields, creating an interdisciplinary dialogue about networks of networks.

Best regards,
The Netonets organizers,

Antonio Scala, La Sapienza – antonio.scala.phys@gmail.com
Gregorio D’Agostino, ENEA – gregorio.dagostino@enea.it

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!

Networks of Networks – NetSci 2015

The time has finally come! The NetSci conference—the place to be if you are interested in complex networks—is happening next week, from June 1st to June 5th. The venue is in Zaragoza, Spain. You can get all the information you need about the event from the official website. For the third year, I am co-organizing one of its satellite events: the Multiple Network Modeling, Analysis and Mining symposium, this year held jointly with Networks of Networks. The satellite will take place on June 2nd. As I previously said, unfortunately I am not going to be physically present in Span, and that makes me sad, because we have a phenomenal program this year.

We have four great invited speakers: Giovanni Sansavini, Rui Carvalho, Arunabha Sen and Katharina Zweig. It is a perfect mix between the infrastructure focus of the networks of networks crowd and the multidisciplinary approach of multiple networks. Sansavini works on reliability and risk engineering, while Carvalho focuses on characterizing and modeling networks in energy. Sen and Zweig provide their outstanding experience in the fields of computer networks and graph theory.

Among the contributed talks I am delighted to see that many interesting names from the network analysis crowd decided to send their work to be presented in our event. Among the highlights we have a contribution from the group of Mason Porter, who won last year’s Erdos Prize as one of the most outstanding young network scientists. I am also happy to see contributions from the group of Cellai and Gleeson, with whom I share not only an interest on multiplex networks, but also on internet memes. Contributions from groups lead by heavyweights like Schweitzer and Havlin are another sign of the attention that this event has captured.

I hope many of you will attend this seminar. You’ll be in good hands: Gregorio D’Agostino, Przemyslaw Kazienko and Antonio Scala will be much better hosts than I can ever be. I am copying here the full program of the event. Enjoy Spain!

A Marriage of Networks

My personal quest as ambassador of multiple networks at NetSci (previous episodes here and here) is continuing also this year. And, as every year, there are new exciting things coming along. This year, the usual satellite I organize is marrying another satellite. We are in fact merging our multiple networks with the Networks of Networks crowd. Networks of Networks is a society holding its own satellite at NetSci since quite a while. They are also interested in networks with multiple node and edge types, with more attention to infrastructure-flavored networks: computer networks, power grids, water infrastructure and so on. We are very excited to see what the impact between multiple networks and networks of networks, directed in particular by Antonio Scala and Gregorio D’Agostino, will generate.

The marriage is a promising one because, when talking about multiple networks and infrastructure, technical knowledge is dispersed among experts of different sectors – system operators from different industries (electric, gas, telecommunication, food chain, water supply, etc) – while researchers from different fields developed a number of different strategies to deal with these complex objects – from computer science to physics, from economics to humanities. To be exposed to these approaches and to confront one’s understanding of the potentialities of the analysis of multiple interdependent networks is key for the development of a common language to integrate the knowledge from all sectors. Complex Networks can be a common language for the needed federated approaches at both microscopic and macroscopic level. This satellite is here exactly to foster the development of such common language.

The usual practical information you might find useful:

  • The satellite will take place on June 2nd, 2015. It will be held, as usual, jointly with the other NetSci satellites. The location will be Zaragoza, Spain. The information about how to get there is included in the NetSci website.
  • The official website of the satellite is hosted by the Net-o-Nets parent website. The official page is this one. Information about the satellite is pretty bare-bones at the moment, but we’ll flesh it out in the following weeks.
  • We are open to submissions! You can send in your abstract and we’ll consider you for a contributed talk. The submission system goes through EasyChair, and this is the official link. The deadline for submission is April 19th, 2015 and we will notify you on April 29th.

Sadly, I will not be present in person to the event due to conflicting schedules. So I will not be able to write the usual report. I’ll leave you in the best hands possible. Submit something, and stop by in Zaragoza: you’ll find an exciting and stimulating crowd!
