Document and Query Expansion Models for Blog Distillation
Jaime Arguello, Jonathan L. Elsas, Changkuk Yoo, Jamie Callan, Jaime Carbonell · 2008
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 us-ing a corpus that combines several different represen-tations of the documents, using both the feed XML and permalink HTML, and apply initial experiments with spam filtering. 1
