Leopar is a parser for natural languages which is based on the formalism of Interaction Grammars  [59] . It is open-source (under the CECILL License http://www.cecill.info ) and it is developed using the InriaGforge platform (http://gforge.inria.fr/projects/semagramme/ ).

The main features of current version of the software are:

  • automatic parsing of a sentence or a set of sentences,

  • dependency and parse-tree representation of sentences,

  • interactive parsing (the user chooses the couple of nodes to merge),

  • visualization of grammars produced by XMG-2 or of sets of description trees associated to some word in the linguistic resources.

In 2014, a new conversion from parse-tree representation to dependency representation was implemented to take benefit of the linguistic principles that were defined and used in [36] .
