This paper discusses argument structure asymmetries observed in linguistic expressions, and presents the main features of a parser that recovers them incrementally. It is argued that the recovery of argument structure asymmetries, expressed in terms of the asymmetric c-command relation, is crucial in Information Retrieval and Question Answering. A consequence is drawn for efficient software design.
