The University of Otago submitted three element runs and three passage runs to the Relevance-in-Context task of the ad hoc track. The best Otago run was a whole-document run placing 7th. The best Otago passage run placed 13th while the best Otago element run placed 31st. There were a total of 40 runs submitted to the task. The ad hoc result reinforced our prior belief that passages are better answers than elements and that the most important aspect of the focused retrieval is the identification of relevant documents. Six runs were submitted to the Link-the-Wiki track. The best Otago run placed 1st (of 21) in file to file automatic assessment and 6th (of 28) with manual assessment. The Itakura & Clarke algorithm was used for outgoing links, with special attention paid to parsing and case sensitivity. For incoming links representative terms were selected from the document and used to find similar documents.
