Wikisearching and Wikilinking

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.
