Overview of the TREC 2006 Blog Track



Iadh Ounis, Maarten de Rijke, Craig Macdonald, Gilad Mishne, Ian Soboroff


The Blog track began this year, with the aim to explore the information seeking behaviour in the blogosphere. For this purpose, a new large-scale test collection, namely the TREC Blog06 collection, has been created. In the first pilot run of the track in 2006, we had two tasks, a main task (opinion retrieval) and an open task. The opinion retrieval task focuses on a specific aspect of blogs: the opinionated nature of many blogs. The second task was introduced to allow participants the opportunity to influence the determination of a suitable second task (for 2007)on other aspects of blogs, such as the temporal/event-related nature of many blogs, or the severity of spam in the blogosphere.
