ISDT (Italian Stanford Dependency Treebank) is a resource annotated according to the Stanford dependencies scheme, obtained through a semi-automatic conversion process starting from MIDT. MIDT in turn was obtained merging two existing Italian treebanks: TUT and ISST-TANL.

The Stanford annotation scheme was adapted to the specificity of the Italian language. We refer to [4] for a dscussion.
