Within this article, we present the application of the AutoSummENG method within the TAC 2009 AESOP challenge. We further oﬀer an alternative to the original AutoSummENG method, which uses an additional operator of the n-gram graph framework to represent a set of documents with a single, merged graph. This alternative shows promising eﬀectiveness and suggests that n-gram graphs and their operators can constitute an eﬀective and updatable text representation method.
