Abstract
ikipedia is the worlds largest online encyclopedia
and is used by billions of people a year. Studying its patterns of
access and editing can inform us with novel insights into human
knowledge seeking behaviour and online knowledge construction,
and the supply and demand of online knowledge repositories.
As an online encyclopedia, Wikipedia is often characterised by
its network structure, as well as its semantic content. Further
understanding this network and semantic structure, as well as its
relationship to knowledge gaps and collective knowledge seeking
behaviour can help make Wikipedia a better tool for its many
users. As different cultures and languages use Wikipedia differently,
at different times and events, I aim to structure my research
across these dimensions. In this report, I detail approaches
to study network and semantic structure using measurements
constructed using neural network inspired embeddings, as well
as measurements based on network structure and Wikipedia
usage. I review three research articles, each relating to either of
culture, language, temporal analysis, and
