        abstract = {Conceptual Graphs (CGs) are a natural and intuitive notation for expressing first-order logic statements. However, the task of performing inferences with a large-scale CG knowledge base remains largely unexplored [...] in this paper we show how a method used elsewhere for achieving tractability --- namely the use of \emph{access paths} --- can be applied to conceptual graphs [...]},
