Abstract
CWI and University of Twente used PF/Tijah, a flexible
XML retrieval system, to evaluate structured document retrieval, multimedia
retrieval, and entity ranking tasks in the context of INEX 2007.
For the retrieval of textual and multimedia elements in the Wikipedia
data, we investigated various length priors and found that biasing towards
longer elements than the ones retrieved by our language modelling
approach can be useful. For retrieving images in isolation, we found that
their associated text is a very good source of evidence in the Wikipedia
collection. For the entity ranking task, we used random walks to model
multi-step relevance propagation from the articles describing entities to
all related entities and further, and obtained promising results.
