CSIRO's Participation in INEX 2006

In this year’s INEX[1] participation, CSIRO participated in the Ad-hoc Track, contributing to three of the four given tasks, namely the Thorough Task, the Focussed Task and the Best in Context Task. In order to use CSIRO’s plain text search engine PADRE[2] we had to preprocess the collection in a similar manner to the approach taken by our group in 2002[3]. We split the documents in subdocuments according to the elements that we need to retrieve and indexed the files with PADRE. In a first step we extracted query elements from the INEX topics. Then the query processor generated PADRE queries and post-processed the results according to specifications for each run.
