A Search Tool for (parallel) Universal Dependencies treebanks that runs in your browser.
While STUnD can also be used on single dependency treebanks, its most unique feature is that it allows running parallel queries on sentence-aligned UD treebanks by combining UD-based subtree alignment with UD tree pattern matching.
STUnD is a Haskell+JavaScript web application built by Herbert Lange and Arianna Masciolini based on an initial prototype by Arianna Masciolini.
