Evolving demographics: a dynamic clustering approach to analyze residential segregation in Berlin EPJ Data Sci. (IF 3.6) Pub Date : 2024-03-12
Abstract This paper examines the phenomenon of residential segregation in Berlin over time using a dynamic clustering analysis approach. Previous research has examined the phenomenon of residential segregation in Berlin at a high spatial and temporal aggregation and statically, i.e. not over time. We propose a methodology to investigate the existence of clusters of residential areas according to migration

Large-scale digital signatures of emotional response to the COVID-19 vaccination campaign EPJ Data Sci. (IF 3.6) Pub Date : 2024-03-08
Abstract The same individuals can express very different emotions in online social media with respect to face-to-face interactions, partially because of intrinsic limitations of the digital environments and partially because of their algorithmic design, which is optimized to maximize engagement. Such differences become even more pronounced for topics concerning socially sensitive and polarizing issues

In her 2021 IC2S2 keynote talk, “Critical Data Theory,” Margaret Hu builds off Critical Race Theory, privacy law, and big data surveillance to grapple with questions at the intersection of big data and legal jurisprudence. As a legal scholar, Hu’s work focuses primarily on issues of governance and regulation—examining the legal and constitutional impact of modern data collection and analysis. Yet,

Thinking spatially in computational social science EPJ Data Sci. (IF 3.6) Pub Date : 2024-02-26
Abstract Deductive and theory-driven research starts by asking questions. Finding tentative answers to these questions in the literature is next. It is followed by gathering, preparing and modelling relevant data to empirically test these tentative answers. Inductive research, on the other hand, starts with data representation and finding general patterns in data. Ahn suggested, in his keynote speech

Charting mobility patterns in the scientific knowledge landscape EPJ Data Sci. (IF 3.6) Pub Date : 2024-02-20
Abstract From small steps to great leaps, metaphors of spatial mobility abound to describe discovery processes. Here, we ground these ideas in formal terms by systematically studying mobility patterns in the scientific knowledge landscape. We use low-dimensional embedding techniques to create a knowledge space made up of 1.5 million articles from the fields of physics, computer science, and mathematics

On the duration of face-to-face contacts EPJ Data Sci. (IF 3.6) Pub Date : 2024-01-10
Abstract The analysis of social networks, in particular those describing face-to-face interactions between individuals, is complex due to the intertwining of the topological and temporal aspects. We revisit here both, using public data recorded by the sociopatterns wearable sensors in some very different sociological environments, putting particular emphasis on the contact duration timelines. As well

Computational social science with confidence EPJ Data Sci. (IF 3.6) Pub Date : 2024-01-10 Carolina E. S. Mattsson
There is an ongoing shift in computational social science towards validating our methodologies and improving the reliability of our findings. This is tremendously exciting in that we are moving beyond exploration, towards a fuller integration with theory in social science. We stand poised to advance also new, better theory. But, as we look towards this future we must also work to update our conventions

Computational social science is growing up: why puberty consists of embracing measurement validation, theory development, and open science practices EPJ Data Sci. (IF 3.6) Pub Date : 2023-12-12 Timon Elmer
Puberty is a phase in which individuals often test the boundaries of themselves and surrounding others and further define their identity – and thus their uniqueness compared to other individuals. Similarly, as Computational Social Science (CSS) grows up, it must strike a balance between its own practices and those of neighboring disciplines to achieve scientific rigor and refine its identity. However
