  In this work, we aim to investigate the impact of location (different
countries) on bias in search results. For this, we use the search results of
Google and Bing in the UK and US locations. The query set is composed of
controversial queries obtained from ProCon.org that have specific ideological
leanings as conservative or liberal. In a previous work, researchers analyse
search results in terms of stance and ideological bias with rank and relevance
based measures. Yet, in the scope of this work, by using the query subset of
controversial queries we examine the effect of location on the existence of
bias as well as the magnitude of bias difference between Bing and Google. Note
that this study follows a similar evaluation procedure. Our preliminary results
show that location might affect the retrieval performance of search engines as
well as the bias in the search results returned by Bing and Google towards the
controversial queries.
