Decoding revision mechanisms in Wikipedia
Research on knowledge collaboration in Wikipedia has predominately focused on metadata at the article level or editor-centric analyses, often overlooking the complexities of knowledge collaboration and its contextual dependencies. This study takes a novel, fine-grained approach to investigating revision mechanisms in Wikipedia’s knowledge collaboration. By considering modified sentences as carriers of collective knowledge and spaces in which epis…
Veiled conspiracism
Digital communication venues are essential infrastructures for anti-democratic actors to spread harmful content such as conspiracy theories. Capitalizing on platform affordances, they leverage conspiracy theories to mainstream their political views in broader public discourse. We compared the word choice, language style, and communicative function of conspiracy-related content to understand its platform-dependent differences and convergence. Our …

We present Local Graph-based Dictionary Expansion (LGDE), a method for data-driven discovery of the semantic neighbourhood of words using tools from manifold learning and network science. At the heart of LGDE lies the creation of a word similarity graph from the geometry of word embeddings followed by local community detection based on graph diffusion. The diffusion in the local graph manifold allows the exploration of the complex nonlinear geome…

Landslide Susceptibility Assessment Considering Time-Varying of Dynamic Factors
The selection of disaster-inducing factors and the construction of assessment models are two important stages in landslide susceptibility assessment. Existing research has neglected the influence of time-varying dynamic factors on landslide susceptibility. On the contrary, the best assessment model that fits the characteristics of disaster-pregnant environment in a certain area needs to be determined through a large number of comparative studies.…
Stability Assessment of Shallow Soil Landslide and Activating Rainfall Threshold
The transient rainfall infiltration and grid-based regional slope-stability (TRIGRS)-Scoops three-dimensional (3D) coupling model combines the influences of rainfall infiltration and 3D topography on slope safety. However, the Scoops 3D model defines the physical and mechanical parameters of underground materials with a uniform or layered method, which cannot describe the variability in the horizontal direction. To address this limitation, a meth…
Diffusion dynamics and digital movement
Diffusion is a long-established concept that deals with the mechanisms explaining the prevalence of social movements. However, previous empirical studies on digital movement merely used diffusion as a term referring to increasing numbers of posts or public attention, without distinguishing what is diffused nor asking how information is diffused. Studies applying social network analysis have restricted themselves to retweet networks from a static …
Challenges of and approaches to data collection across platforms and time
Taking the example of conspiracy-related communication online as one form of contentious politics, this study examines the data collection challenges for multidimensional comparative research across platforms, time, and cultural embeddings. It compares the architectures and features relevant to data collection, access regimes, and use cultures for a set of digital platforms and communication venues. Differentiating between actor- and content-base…
Social Collectives and Networked Movement
Initiated by Greta Thunberg and carried by students who skip school every Friday to call for climate justice and the safeguarding of their future, FridaysForFuture emerged and proliferated along with both recognition and criticism. This study analyzes diffusion dynamics and connectivity formation in the German-speaking #FridaysForFuture network from its emergence to its expansion. Based on a diffusion network and cascade analysis (N = 238,458), i…
Understanding digitally networked action
Digitally networked action (Bennett & Segerberg, 2012) has become a prominent political reality. This article explores the evolution of digitally networked action, considering the Twitter hashtag #HomeToVote in 2018 as a relevant case. The case study features the return of Irish expatriates to their home country to vote in the referendum on abortion rights, since no postal votes were available to Irish citizens abroad. We investigated how actors …
