MIDT Resources

Available MIDT resources include data obtained by automatic conversion from

  • ISST-TANL, developed as a joint effort by the Istituto di Linguistica Computazionale (ILC–CNR) and the University of Pisa and originating from the Italian Syntactic–Semantic Treebank or ISST; a previous version (ISST-CoNLL) was used for the CoNLL-2007 Shared Task on multilingual dependency parsing;
  • the Turin University Treebank (TUT), developed by the NLP group of the University of Turin.

A set of around 2000 questions where produced directly in the MIDT format and revised.
