Abstract:
When contributing content on large online platforms, producers of user-generated
content have to decide where to contribute. On a complex and dynamic platform like
Wikipedia, this decision is expected to depend on the way the content is organized.
We analyse whether the hyperlinks on Wikipedia channel the attention of producers
towards more central articles. We observe a sample 7; 635 articles belonging
to the category \Economics" on German Wikipedia over 153 weeks and measure
their centrality both within this category and in the network of over one million
German Wikipedia articles. Our analysis reveals that an additional link from the
observed category is associated with around 140 bytes of additional content and
with an increase in the number of authors by nearly 0:5. Moreover we observe that
the rate of content generation increases notably when previously unlinked articles
get connected to the main cluster in the category.
