CLARIT Compound Queries and Constraint-Controlled Feedback in TREC-5 Ad-Hoc Experiments

this paper we present a detailed description and analysis of the experiments with feedback control. In Section 3 we discuss the official TREC-5 experiments, CLTHES and CLCLUS. We summarize our findings in Section 4. The Appendix contains information about system parameters and experiments performed in the TREC-5 Very Large Collection (VLC) track. 2.
