WHAT IS JEX

The JRC EuroVoc Indexer JEX
(http://langtech.jrc.ec.europa.eu/Eurovoc.html) is readily trained
multi-label categorisation software that assigns categories from the
large-scale and wide-coverage EuroVoc Thesaurus
(http://eurovoc.europa.eu/)  (consisting of thousands of
categories). JEX is being distributed together with its training data
(twenty to forty thousand documents per language). JEX has been trained
for 22 languages on mostly parallel text (texts and their professionally
produced translations). You can re-train JEX with your own documents,
and even using your own categorisation scheme. JEX provides a graphical
user interface (GUI), a command line option for batch processing, as
well as an API.

WHAT JEX CAN BE USED FOR

JEX can be used fully automatically or as an interactive tool to support
professional librarians in their work.

JEX has also many potential uses in the field of Computational
Linguistics because it is highly multilingual and it lends itself to
cross-lingual tasks:

 - Use for multilingual classification experiments, e.g. to test the
   impact of different document representations, etc. (n-grams, lemmas,
   POS, word-sense disambiguation, …), across different languages and
   language families;

 - Use as input to other text mining applications, e.g.

 - Detect document translations (Pouliquen et al. 2004);

 - Cross-lingual plagiarism detection (Potthast et al. 2010);

 - Link related documents across languages (Pouliquen et al. 2008);

 - Support the lexical choice in Machine Translation;

 - Rank sentences in topic-specific summarisation;
