On the Effectiveness of Relevance Profiling

David J. Harper, David Lee
2004 Australasian Document Computing Symposium  
The relevance profiling process proved highly effective in retrieving relevant pages within the electronic book, and exhibits stable performance over a range of sliding window sizes.  ...  The experimental study provides evidence for the effectiveness of relevance profiling for within-document retrieval, with the caveat that the experiment was conducted with a particular electronic book.  ...  I also thank Margery Murray for her invaluable assistance in preparing the manuscript. Finally, we would like to thank the anonymous referees for their insightful comments on the submitted paper.  ...

Towards Stochastic Simulations of Relevance Profiles

Kevin Roitero, Andrea Brunello, Julián Urbano, Stefano Mizzaro
2019 Proceedings of the 28th ACM International Conference on Information and Knowledge Management - CIKM '19  
Recently proposed methods allow the generation of simulated scores representing the values of an effectiveness metric, but they do not investigate the generation of the actual lists of retrieved documents  ...  We show how the simulated relevance profiles are realistic under various analyses.  ...  ACKNOWLEDGMENTS JU was funded by the EU H2020 programme (770376-2 TROMPA).  ...

Query-Based Document Skimming: A User-Centred Evaluation of Relevance Profiling [chapter]

David J. Harper, Ivan Koychev, Yixing Sun
2003 Lecture Notes in Computer Science  
ProfileSkim bases within-document retrieval on computing a relevance profile for a document and query; FindSkim provides similar functionality to the web browser Find-command.  ...  The experiments confirm the potential of relevance profiling to improve query-based document skimming, which should prove highly beneficial for users trying to identify relevant information within long  ...  Finally, we would like to offer our heartfelt gratitude to the 30 participants who gave freely of their time, and strived so hard to find "relevance feedback" in Part 1 of the book!  ...
