Geriaoueg is a set of scripts which use apertium morphological analysers (see list of dictionaries) and a bilingual wordlist to provide vocabulary help when browsing the web. The software can be found in SVN under
apertium-tools/geriaoueg, currently it works with most web browsers with the exception of Internet Explorer.
In order to set up the software for a new pair of languages you will need a morphological analyser which outputs Apertium format analyses (e.g. with lttoolbox or sfst) and a bilingual tab-separated wordlist. It is hoped that this will make Apertium format resources more useful to more people, and be a step toward building a full machine translation system.
