Retrieval and Feedback Models for Blog Distillation
This paper presents our system and results for the Feed Distillation task in the Blog track at TREC 2007. Our experiments focus on two dimensions of the task: (1) a large-document model (feed retrieval) vs. a small-document model (entry or post retrieval) and (2) a novel query expansion method using the link structure and link text found within Wikipedia.
