Previous work on discourse parsing has mostly relied on surface syntactic and lex- ical features; the use of semantics is lim- ited to shallow semantics. The goal of this thesisistoexploiteventsemanticsinorder to build discourse parse trees (DPT) based on informational rhetorical relations. Our work employs an Inductive Logic Pro- gramming (ILP) based rhetorical relation classifier, a Neural Network based dis- course segmenter, a bottom-up sentence level discourse parser and a shift-reduce document level discourse parser.
