Introduction to historical (social) network analysis – Part 2

by Demival Vasques Filho

In the first part of this blog post, we discussed the first studies in graph theory and social network analysis. Then, we introduced several concepts: random networks, weak ties, two-mode networks, centrality measures, the focus theory, network visualization, and structural holes. Now, let us move on to some applications and yet new concepts!

Introduction to historical (social) network analysis – Part I

by Demival Vasques Filho

Last September, as part of our seminar series, “60 minutes of DH”, at the IEG, I presented an introduction to historical (social) network analysis. In the talk, I gave an overview of the field’s history, discussing landmark papers, in my opinion. It was a mix of going through papers fundamental to shaping the discipline (a kind of consensus in the network science/social network analysis communities) and those that are important to me or I like. In the following, I will recount this biased – based on my opinion – talk about the evolution of networks research in this two-part post.

Diving into Reddit: authority networks in history forums

by Daniela Linkevicius de Andrade and Demival Vasques Filho

Writing history in the 21st century means considering the digital space as a significant space for the production of historical knowledge, especially since dichotomies such as “offline” and “online” fail to do justice to how “real” and “digital” intertwine. These elements, currently approached as complementary, imply that one of the challenges that historians now face is understanding how the digital is constituted as part of our experience, playing a great influence in the way we interpret and perceive the world. If the digital modify every aspect of our lives, it is plausible to ask what this would mean for the historical field, especially regarding standards of authority, which are the pillars of the discipline. For this purpose, our objective in this project is to identify and analyze what types of authority networks we can find in Reddit history forums. „Diving into Reddit: authority networks in history forums“ weiterlesen

Research visit in New Zealand: Modelling the spread of COVID-19 on higher-order networks

At the beginning of March, I went to New Zealand for a research visit with a planned duration of four weeks. This visit was part of a collaboration involving the IEG DH Lab and Te Pūnaha Matatini, a New Zealand centre of research excellence for complex systems and data science hosted by the University of Auckland’s Department of Physics.

The main goal of the visit was to further develop our research on the structure of higher-order networks, that is, networks which account for interactions between individuals stemming from their membership to groups. Higher-order networks are usually represented by either bipartite (two-mode) networks, or hypergraphs, or simplicial complexes. Our last publications on this topic can be seen in the Journal of Complex Networks and the Physical Review E (also available on arXiv, here and here).

I arrived about one week before New Zealand closed its borders to the world, allowing only citizens and long-term residents to enter into the country. „Research visit in New Zealand: Modelling the spread of COVID-19 on higher-order networks“ weiterlesen

IEG DH Lab at NetSciX 2020

by Demival Vasques Filho

I just returned from Japan, where I attended the NetSciX (the Winter edition of NetSci) conference. It was an enjoyable event, with inspiring presentations and discussions. Here, I will share with you some of my perceptions about it!
