itWaC: Italian corpus from the .it domain

The Italian web corpus (itWaC) is an Italian corpus made up of texts collected from the Internet. The corpus consists of 1.5 billion words and was prepared by Marco Baroni. Texts are part-of-speech tagged and lemmatized with the TreeTagger tool. Moreover, users can explore the grammatical and collocational behavior of Italian words as a result of a word sketch grammar prepared Marco Baroni and later updated by Valentina Efrati and Francesca Masini (TRIPLE lab, Roma Tre University). The corpus is cleaned and deduplicated.
