The document summarizes two data science projects analyzing biographical networks on Wikipedia across multiple language editions. The first project identified biographical articles in the English Wikipedia and analyzed networks of links between them in 15 other languages. The second project analyzed networks of links between all Wikipedia articles in 24 languages and extracted features of biographical articles like birthplace, date, and gender. The document concludes by discussing challenges like gender gaps among Wikipedia editors and potential for future work investigating connections between editor demographics and article topics.

9. CONCLUSION
Finally, the gender gap among Wikipedia editors is a serious concern
for the community, and has been related to the topics covered in the encyclopedia.
Our results point out a very small presence of females also among the most central persons
in the encyclopedic content, suggesting the link between these two phenomena as an
intriguing subject for future investigation.

the fact that he laid the foundations for the modern biological naming scheme
so that plenty of articles about animals, insects and plants point to the
Wikipedia article about him, which strongly increases the PageRank probability.”
