UPDATED VERSIONS OF OVI CORPUS (SEPTEMBER 2025)

15-09-2025

Updated versions of the OVI Corpus, the TLIO Corpus, and the OVI Corpus of Early Italian have been released: they are aligned with the structure developed in the RENOVO Project (Regenerating the OVI Corpus: Ren​ewal and Optimization of Methods, Contents and Tools  - PRIN 2017), aimed at the philological and textual renewal of the two corpora in continuity with CoVo Project (The corpus of the Italian vocabulary of the origins:philological update and interoperability - PRIN 2015). See the  criteria for updating.
TLIO ​Corpus

It is a lemmatized corpus, and includes the texts of reference for the TLIO.  The editions of 8 texts already present in outdated editions in the TLIO Corpus have been updated (see list here) and 95 new texts hitherto absent have been inserted (see list here). 

The new version of the TLIO Corpus that today is published online includes 3,452 texts (with an increase of 99 units compared to the June 16, 2025 version), for a total of 24,285,827 occurrences (with an increment of 125,630 occurrences), 503,539 distinct graphic forms, 128,196 lemmas, and 4,904,409 lemmatized occurrences (with an increment of 47,745 occurrences).

OVI ​Corpus

It is a non-lemmatized corpus (but searchable with the “lemmi muti” GattoWeb function), which includes the TLIO Corpus and extends it to include all the published texts dating before the end of the XIV Century: it is the corpus that aims to allow the interrogation of the entire textual heritage of early Italian. 

There have been inserted 16 texts so far absent, which do not fall within the inclusion criteria of the TLIO Corpus (see list here). The new version of the OVI Corpus that today is published online includes 3,840 texts (with an increase of 115 units compared to the June 16, 2025 version), for a total of 31,222,521 occurrences (with an increment of 397,235 occurrences), and 566,393 distinct graphic forms.
