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  
We show how the simulated relevance profiles are realistic under various analyses.  ...  In this paper we address this limitation: we present an approach that exploits an evolutionary algorithm and, given a metric score, creates a simulated relevance profile (i.e., a ranked list of relevance  ...  GENERATION OF RELEVANCE PROFILES We model the stochastic generation of relevance profiles as an optimization problem, adopting an evolutionary based approach.  ...
