Title: Global Revision in Summarisation: Generating Novel Sentences with 
Prim's Algorithm
Speaker: Stephen Wan

Abstract:
In abstract-like summarisation, extracted sentences containing key content 
are often revised to improve the coherence of the overall summary. In this 
work, we consider the task of Global Revision, in which a key sentence is 
revised and supplemented with additional content from the original 
document. Specifically, this task comprises two subtasks: selecting 
content; and grammatically ordering content, the focus of this paper. 
Using statistical dependency models, we search for a Maximal Spanning 
(Dependency) Tree that structures recycled words and phrases
to form a novel sentence. Combining a modified version of Prim's algorithm 
with a four-gram language model, we evaluated our system on a sentence 
regeneration task obtaining Bleu scores of .30, a statistically 
significant improvement above the baseline.
