Title: Annotating the Penn Discourse Treebank: A bottom-up approach to
discourse structure

Abstract:
In this talk I will present a new discourse level annotation project,
the Penn Discourse Treebank (PDTB). In PDTB, we annotate discourse
connectives and their arguments. Rather than starting from abstract
discourse relations, we describe an approach to annotating a large
scale corpus in terms of a more basic characterization of discourse
structure. The PDTB provides a discourse layer of annotation on top of
the existing Penn Treebank (syntactic annotation) and PropBank
(semantic annotation) thus supporting the extraction of useful
syntactic and semantic features and providing a rich substrate for the
development and evaluation of practical algorithms. During the talk I
will give a brief overview of the PDTB project and present a detailed
analysis of inter-annotator agreement for a fraction of the corpus.
Time permitting, I will also talk about our latest studies on sense
disambiguation of connectives.
