Did I really mean that? Applying automatic summarisation techniques to formative feedback

(2)This paper reports on an application that delivers automated formative feedback designed to help university students improve their assignments. (3)The aim of the system is to improve the confidence and skills of the user by promoting selfdirected learning through metacognition. (4)The system focuses on the content of an essay by using automatic summarisation techniques, automatic structure recognition, diagrams, animations, and interactive exercises that promote reflection. (15)The system is currently undergoing initial exploratory rounds of testing by ex-student volunteers and will be the subject of two full-scale empirical evaluations starting in September 2013. (1)The main claims of this paper are the application and adaptation of graph-based key word and key sentence ranking methods for a novel purpose, and ensuing observations concerning the suitability of two different centrality algorithms for the purposes of key word extraction
