An european news categorization project was NAMIC
(http://www.dcs.shef.ac.uk/nlp/namic/).
Text categorization test collections for your problem are (in English):
*
Reuters-21578
(http://www.daviddlewis.com/resources/testcollections/reuters21578/)
* Reuters Corpus, Volume 1
(http://about.reuters.com/researchandstandards/corpus/) (use this, is much
bigger and challenging).
You can get topics from them.
Also you can use sections of newspapers.
For information on TC, and resources for Italian, contact the Istituto di
Linguistica Computazionale - Consiglio Nazionale Ricerche
(http://www.ilc.cnr.it/indexflash.html) and Fabrizio Sebastiani
(http://faure.iei.pi.cnr.it/~fabrizio/), from the Istituto di Scienza e
Tecnologia dell'Informazione - Consiglio Nazionale Ricerche
