[Corpora-List] Standard ontology for document classification?

Xabier,



The multilingual (over 20 languages), wide-coverage Eurovoc thesaurus with
its approximately 6000 classes has a subset of about 60 science-oriented
classes, plus many related terms and classes in other domains that may also
be useful (e.g. politics, law, economics, trade, finance, social questions,
education, employment, transport, envirosnment, agriculture, energy,
geography). The science-oriented classes provide the major science domains,
but may not be detailed enough for your purposes. Please check out for
yourself.



Eurovoc is browsable at http://europa.eu/eurovoc/ and is available free for
research purposes. For details on where to get Eurovoc, see
http://langtech.jrc.it/0509_EU-Enlargement-Workshop.html#HOW_TO_GET_THE_AC_C
ORPUS_AND_EUROVOC.



Eurovoc was developed for manual cataloguing of mainly parliamentary
documents, but collections of multi-label classified documents such as the
JRC-Acquis (http://langtech.jrc.it/JRC-Acquis.html) have been used to train
an automatic multi-label Eurovoc classification system.



I hope this helps. All the best,



Ralf

Dear all,

I want to classify many scientific documents among different categories

based on their knowledge area, such as health, geography...

My question is whether there is a standard ontology for such a

classification.

Regards,
