Abstract: This paper presents the CMU submission to the 2008 TREC blog distillation track. Similar to last year’s experiments, we evaluate dierent retrieval models and apply a query expansion method that leverages the link structure in Wikipedia. We also explore using a corpus that combines several dierent representations of the documents, using both the feed XML and permalink HTML, and apply initial experiments with spam filtering.
