چکیده
In this paper, we describe the Centre for Interactive Systems Research’s participation in the INEX 2006 adhoc track. Rather than using a fieldweighted BM25 model in INEX 2005, we revert back to using the traditional BM25 weighting function. Our main research aims in this year are to investigate the effects of document filtering by result record cut-off, element filtering by length cut-off and the effect of using phrases. The initial results show the latter two methods did not do well, while the first one did well on FOCUSED TASK and RELEVANT IN CONTEXT TASK. Finally, we propose a novel method for BEST IN CONTEXT TASK, and present our initial results.

متن کاملThe Heterogeneous Collection Track at INEX 2006
While the primary INEX test collection is based on a single DTD, it is realistic to assume that most XML collections consist of documents from different sources. This leads to a heterogeneity of syntax, semantics and document genre. In order to cope with the challenges posed by such a diverse environment, the heterogeneous track was offered at INEX 2006. Within this track, we set up a collectio...
