The TREC Blog track aims to explore information seeking behaviour in the blogosphere, by building reusable test collections for blog-related search tasks. Since, its advent in TREC 2006, the Blog track has led to much research in this growing field, and encapsulated cross-pollination from natural language processing research. This paper recaps on the tasks addressed at the TREC Blog track thus far, covering the period 2006 - 2009. In particular, we describe the used corpora, the tasks addressed within the track, and the resulting published research.
