- Can Information Retrieval Systems Be Improved Using Quantum Probability?
Massimo Melucci
In recent years a great deal of attention and research have been paid to the exploitation of Quantum Mechanics in Information Retrieval (IR). In this talk I will introduce the basic notions of Quantum IR and will explain how the retrieval decision problem can be formulated within a quantum probability framework in terms of vector subspaces rather than in terms of subsets as it is customary to state in classical probabilistic IR. Hence I will show that ranking by quantum probability of relevance in principle yields higher expected recall than ranking by classical probability at every level of expected fallout and when the parameters are estimated as accurately as possible on the basis of the available data.
