In this thesis: "Bing vs. Google - a measurement of the effectiveness and overlap of two search engines", the internet search engines Bing and Google are measured for their effectiveness and ability to place the most relevant results in the beginning of the search results. This is measured with the metrics: precision, cumulated gain and discounted cumulated gain. The overlap between the search engines is measured, to see if the search engines are able to present unique results, and to see if the search engines complement each other, or if it is advisable to just use one of them.
The results indicate that the effectiveness of Google is better than that of Bing. The search engines are relatively good at placing the most relevant results in the beginning of the search results, but none of the search engines succeed in placing the generally most relevant results at rank 1. The overlap is fairly small, but larger on page 1 of the search result than other measurements of overlap have shown. Since most of the searches in Google and Bing have unique, relevant results in the top five search results, it is seen as advisable to complement the search engines with each other, even though the effectiveness of Google is better in general.
