Alpage: Transition-based Semantic Graph Parsing with Syntactic Features
Corentin Ribeyre, Éric Villemonte de la Clergerie, Djamé Seddah · 2014
This paper describes the systems deployed by the ALPAGE team to participate to the SemEval-2014 Task on Broad-Coverage Semantic Dependency Parsing.We developed two transition-based dependency parsers with extended sets of actions to handle non-planar acyclic graphs.For the open track, we worked over two orthogonal axes -lexical and syntactic -in order to provide our models with lexical and syntactic features such as word clusters, lemmas and tree fragments of different types.
