GoPatents helps users to filter patent search results to their needs. Using its background knowledge results can be systematically classified, filtered, and summarised, thus drastically reducing time in business intelligence and information.

GoWeb helps users to get an overview over web search results. While few users of classical search engines ever go beyond the top 10 results, GoWeb provides a systematic overview over the first 1000 Yahoo search results. Users can navigate freely through these snippets using GoWeb biomedical background knowledge.

Find42.com is a semantic search engine for the internet. It has a very small knowledge-base included which allows to filter e.g. for pages containing emails, telephone numbers or currencies.
