Improving Search Ranking Through A/B Tests: A Case Study

Location:

Einsteinsaal

Date and time:

Tue, 2011-06-07 15:50 - 16:10

Speaker:

Hannes Kruppa

In this case study we are discussing search ranking optimization through live A/B testing -- a well-known method which is used by many large-scale online search engines. The specific example here is about a user feature in Nokia Maps (maps.ovi.com) that let's you discover new places. This user feature is powered by a SOLR-based geographical search engine. For effective ranking optimization we implemented a rank interleaving scheme and collect and evaluate click feedback. The presentation will also highlight the specific caveats of this method.
