This Friday, Wikipedia turns 20 and I thought I should do something about it! I didn’t want to write about how useful Wikipedia is and how it has revolutionised the way we acquire information, or yet again write about edit wars among Wikipedia editors, or perhaps, how we can use Wikipedia to study collective attentionContinue reading “2020 through the global lens of Wikipedia”

The structure of world-stock-market network resembles geographical ties
In a recent paper, we studied 40 stock markets from top GDP countries to analyse the correlations and connections between them. As expected, we did observe strong correlations between ups and downs of these markets at the global level. However, when using Random Matrix Theory we detected the sub-communities of this global network, we realisedContinue reading “The structure of world-stock-market network resembles geographical ties”

What’s the state of the art in understanding Human-Machine Networks?
About a month ago, we finished our 2-year long EC-Horizon2020 project on Human-Machine Networks (HUMANE). The first task of this project was to perform a systematic literature review to see what the state of the art in understanding such systems is. The short answer is that we do not know much! And what we knowContinue reading “What’s the state of the art in understanding Human-Machine Networks?”

New Paper: Personal Clashes and Status in Wikipedia Edit Wars
Originally posted on HUMANE blog by Milena Tsvetkova. Our study on disagreement in Wikipedia was just published in Scientific Reports (impact factor 5.2). In this study, we find that disagreement and conflict in Wikipedia follow specific patterns. We use complex network methods to identify three kinds of typical negative interactions: an editor confronts another editorContinue reading “New Paper: Personal Clashes and Status in Wikipedia Edit Wars”
