Diversity over Continuous Data.
Marina Drosou, Evaggelia Pitoura · 2009
Result diversification has recently attracted much attention as a means of increasing user satisfaction in recommendation systems and web search. In this work, we focus on achieving content diversity in the case of continuous data delivery, such as in the context of publish/subscribe systems. We define sliding-window diversity and present a suite of heuristics for its efficient computation along with some performance results. 1
