LiLa: Linking Latin

Building a Knowledge Base of Linguistic Resources for Latin

Extract of the IT-TB Latin treebank annotated according to UD standards

New UD conversion of the Index Thomisticus Treebank

On 15th November Universal Dependencies (UD) released version 2.3 of its set of annotated treebanks. As per their announcement:

Universal Dependencies is a project that seeks to develop cross-linguistically consistent treebank annotation for many languages with the goal of facilitating multilingual parser development, cross-lingual learning, and parsing research from a language typology perspective.

Thanks to the work of our very own Flavio M. Cecchini and Marco C. Passarotti, and of our Czech colleague Dan Zeman (Prague), UD now includes a new and improved conversion of the Index Thomisticus Treebank (IT-TB). 🤠 This edition of the Latin treebank consists of texts by Thomas Aquinas, specifically books 1, 2 and 3 of the Summa contra Gentiles, and of concordances of the lemma forma found in some of his other works.

The UD v. 2.3 release is available at:
