Abstract
The democratization of the Internet and the perceived "universal" access to online content have long given the impression of progress
and inclusion. However, digital content overwhelmingly represents knowledge produced in English and within the majority world,
reflecting only a fraction of the knowledge created throughout history across diverse cultures. Epistemic violence remains pervasive in
much of the moderated content online, yet its extent is challenging to measure. This paper introduces a novel approach to address this
gap by proposing an Epistemic Violence Index applied to Wikipedia biographies of Latin American women scientists and writers. Our
study involves constructing a graph representation of the Wikipedia network connections for leading female figures in science and
literature from the 19th and 20th centuries. The analysis highlights their connections with influential voices both within the region
and in the majority world, evaluating the reciprocity and imbalance of these relationships. By leveraging these graphs, we compute
an Epistemic Violence Index based on an intersectional set of variables, including gender identity, socio-economic status, and race,
providing an initial step toward quantifying and addressing this persistent issue.

4.2. Comparing communities of
intellectuals
The EVI is now calculated as a weighted average of six dis-
tinct measures, each designed to capture specific aspects of
network dynamics: visibility disparity, lack of reciprocity,
marginalization, lack of influence, exclusion from tightly
knit subgroups, and overall lack of connections. These mea-
sures are derived from appropriately normalized standard
centrality indices, such as degree centrality, betweenness
centrality, Eigenvector centrality, and clustering coefficient,
all scaled to the unit interval. This normalization ensures
that the measures are comparable and can be combined into
a single composite index.
In this section, we build on the previous definition of the
EVI by using network statistics to assign an EVI value to
each node in the graph of interest, rather than comparing
pairs of nodes from the Global North and South. This shift
simplifies the interpretation of the EVI, making it more in-
tuitive and directly applicable to the analysis of a specific
network. By focusing on individual nodes, the EVI pro-
vides a clearer understanding of each node’s position and
influence within the network. Figure 5: EVI Values of Carolina Maria de Jesus’ Contacts
