Verity at TREC-6: out-of-the-box and beyond

The Verity TREC-6 entry focused on the performance of the built-in search facilities of the commercially available Verity engine and explored the impact of simple enhancements. The ad hoc results show that considerable improvements can be achieved through the application of standard and more experimental techniques. The routing results show that respectable performance can be achieved simply through careful parameter tuning.
