1991
Proceedings of the 14th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '91
Preserved Fulltext
Since obtaining relevance judgments and constructing an oplitnal query involve a great deal of effort, in this paper, we develop a framework for organizing the history of optimal retrievals. The j? ...
