Document and query expansion models for blog distillation is a 2008 conference paper written in English by Arguello J., Elsas J.L., Yoo C., Callan J., Carbonell J.G. and published in NIST Special Publication.

[edit] Abstract

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