Ackland to lead Hyperlink Network Analysis Workshop

On Friday, October 7th, from 10:00-12:00p.m. Robert Ackland will be leading a workshop on Hyperlink Network Analysis in Frances Searle Room 1-459 on Northwestern University’s Evanston Campus.

If you plan to attend, please email Marilyn Logan:, by Thursday, September 29.

This presentation will involve a demonstration of hyperlink network analysis using two software packages: the VOSON System (a web-based application for hyperlink
network construction and analysis) and VOSON+NodeXL (a VOSON plugin to the NodeXL Excel 2007/2010 template for social media network analysis). Topics covered
include: creating a hyperlink network (identifying seed URLs, setting the webcrawler parameters); node preparation (methods for filtering and controlling the grouping of web pages); coding of node attributes; basic social network analysis metrics; network visualization; clustering; website content analysis. Participants wanting to use the software are requested to bring their laptops with Mozilla Firefox and VOSON+NodeXL installed, and must have (free) VOSON user account.
See and for information on the VOSON project and software. See for information on NodeXL.

Robert Ackland is a Fellow at the Australian National University, where he conducts empirical social science research into online social and organizational networks. He leads the VOSON project, coordinates the ANU’s Master of Social Research programme and teaches on the social science of the Internet and online research methods. Robert has degrees in economics from the University of Melbourne, Yale University (where he was a Fulbright Scholar) and the ANU, where he gained his PhD in 2001.

Yuval Kalish Workshop

Yuval Kalish, an assistant professor in the Department of Management of Tel Aviv University will be leading a workshop on Wednesday, September 14 from 2:00-5:30 pm in Frances Searle, Room 1.459.
This workshop provides a hands-on tutorial on how to fit Exponential Random Graph (ERG) Models for social selection using Pnet.

If you plan on attending, please RSVP to Marilyn Logan by 5pm September 13.

ERG models have been referred to as the most promising technique for the modeling of social networks (Snijders, 2007), and has wide applications in the area of organizational studies and communication studies. Topics include: the logic of ERG models, Parameter selection and estimation, parameter interpretation, Goodness of Fit, and troubleshooting convergence issues.
We will discuss Multivariate ERG models if time permits and there is participant interest. Participants are requested to bring their laptops after they have downloaded pnet from: and made sure that it works on their computer.

SONIC hosts Take Our Daughters and Sons To Work Day visitors

The SONIC lab was bustling on April 28 with children visiting campus for Take Our Daughters and Sons to Work Day. SONIC led two workshops designed to teach children, ages 10-16, basic concepts in network science. The kids explored network concepts such as degree, balance, and brokerage by examining Harry Potter’s friendship network. Then, they had a chance to apply their newly-learned skills when they constructed their own friendship networks out of M&Ms and pretzel sticks. The workshops were a hit, and we’re hoping to see some of the participants back in a few years in the classes of 2016-2022!

Third International Workshop on Network Theory: Web Science Meets Network Science

Annenberg Networks  Network, Northwestern’s SONIC lab, and Northwestern Institute on Complex Systems (NICO) hosted the Third International Workshop on Network Theory March 4th-6th, followed directly by the NICO Complexity Conference at Northwestern University’s Allen Center. Although the weather in Evanston turned surly, members of the SONIC lab, along with some of the most influential and brilliant scholars involved in network and web science, discussed the future of the field, major challenges, and opportunities for interdisciplinary collaboration. We’ll have photos available in the next couple of days (look out for a new slideshow on our homepage!) and video from the conference talks available by March 21st.

In the meantime, you can read an excellent blog post at the Complexity and Social Networks blog about a talk given by Stanley Wasserman and the discussion that followed by SONIC’s own Brian Keegan, a graduate student in the Media, Technology, and Society program.  There’s also a tweet-record of the official back channel of Third International at #webnetsci.

Our sincere thanks to everyone who participated in the conference!
