For our participation to QALD-5, we developed a system for answering questions on a knowledge base. We proposed an unsupervised method for the semantic analysis of questions, that generates queries, based on graph transformations, in two steps. First step is independent of the knowledge base schema and makes use of very general constraints on the query structure that allows us to maintain semantic ambiguities in different graphs. Ambiguities are then solved globally at the final step when querying the knowledge base.
