The most ambitious application of EXTRAKT is the LexxiNet (formerly Lexiquo) Portal:

www.lexxinet.de

LexxiNet is a meta-search engine which sends search requests to different search engines (Yahoo, Bing, Qwant and Wikipedia).

The original terms of the request are analyzed and word variants as well as synonyms and translations are added to the request. These variants can be added to the original request by a single click.

LexxiNet has a tri-lingual interface,  but is able to analyze requests in 4 languages:

German, French, English, Italian and Spanish.
