摘要

Objective — The goal was to identify potential search engine content bias by comparing pictures ofudselected current and international events, from Google and Bing across Germany and the US. Criteriaudwere developed for (1) completeness, (2) coverage, and (3) weighting of the particular content aspects.udMethods — Empirical analysis was conducted using a hybrid / cross-functional methodology taken fromudthe social sciences (content analysis) and information science (retrieval tests).udResults — Both Google and Bing (1) do not provide complete coverage in neither Germany nor the US,ud(2) both do not cover the three most important content aspects on the first three result positions, andud(3) there do not seem to be significant differences regarding the weighting of the content aspects.udHowever, these results are somewhat limited, due to the methodology and the evaluation.udConclusions — The findings indicate that search engine content bias indeed exists. This could have anudeffect on how public opinions are formed. The topic should be further analyzed, especially in the lightudof effort required for obtaining results of high quality.
