The knowledge base is used to check the factual correctness of the answers first , and then a diagnoser checks the explanation correctness . The diagnoser , based on Dzikovska et al. ( 2008b ) , outputs a diagnosis which consists of lists of correct , contradictory and non-mentioned objects and relations from the student 's answer . At present , the system uses a heuristic matching algorithm to classify relations into the appropriate category , though in the future we may consider a classifier similar to Nielsen et al. ( 2008 ) .
