Title: Seed and Grow: Augmenting Statistically Generated Summary Sentences
using Schematic Word Patterns
Speaker: Stephen Wan

We examine the problem of content selection in statistical novel sentence
generation.  Our approach models the processes performed by professional
editors when incorporating material from additional sentences to support a
key summary sentence, a process we refer to as Sentence Augmentation.  We
propose and evaluate a method called ``Seed and Grow'' for selecting such
auxiliary information. Additionally, we argue that this can be achieved
using schemata based on word association, and advocate a novel use of basic
collocational methods for statistical summary sentence generation.
Evaluation results are supportive indicating that the model significantly
improves above the baseline, supporting our claim that selecting content for
this task is a two-step process.
