Yannick Parmentier is an Associate Professor at Université de Lorraine, France. He got his PhD in Computer Science in 2007 from Henri Poincaré University, Nancy, France. During his PhD, he took part in the design and implementation of the XMG description language and its application to the formal description of French syntax and semantics. In 2007-2008, he was a postdoctoral research fellow at University of Tübingen, Germany, where he worked on symbolic parsing with tree-based grammars. From 2009 to 2017, he was an Associate Professor at Université d'Orléans working on constraint-based approaches in computational linguistics.

Jakub Waszczuk is a post-doctoral research fellow at Heinrich Heine Universität, Düsseldorf, Germany, where he works on syntactic parsing and parsing-driven multiword expressions identification algorithms. He got his PhD in Computer Science in 2017 from Université François Rabelais, Tours, France. During his PhD, he worked on the design and implementation of multiword expression-aware parsing algorithms for tree-based grammars, with the goal of showing that appropriate handling of multiword expressions can help reduce syntactic ambiguity and increase parsing efficiency.
