Wikipedia is one of the most popular sites on the web and an essential knowledge source for millions of web users. As this online encyclopedia significantly shapes our image of the world, its neutrality is of utmost importance. However, past studies demonstrated that Wikipedia is frequently unbalanced or biased in various subject areas. In this work, we analyze one potential bias on Wikipedia,
the so-called western bias, by examining Wikipedia articles about terrorist ncidents. To that end, we investigate pageviews of 2029 articles in the first month after events happened. While our findings do not apply to all events in general, we do find that terrorist incidents happening in the “western world” receive more attention on Wikipedia than those from non-western regions.
