Quatrième Partie: Le débogueur de grammaires sous INTEX

intex system users have to describe linguistic facts with grammars written by the graph editor. When the number of graphs is important, finding and locating errors is a difficult task. In this article, we suggest a solution using a technique derived from computer science: debugging. To debug graphs, we offer an interface belonging to the intex system to help linguists in their works. We explain how we use Earley’s algorithm, borrowed from graph theory, to create the debugger and demonstrate the usefulness of this debugger for building graphs based on examples.
