What can quantum theory bring to information retrieval
Proceedings of the 19th ACM international conference on Information and knowledge management - CIKM '10
The probabilistic formalism of quantum physics is said to provide a sound basis for building a principled information retrieval framework. Such a framework can be based on the notion of information need vector spaces where events, such as document relevance or observed user interactions, correspond to subspaces. As in quantum theory, a probability distribution over these subspaces is defined through weighted sets of state vectors (density operators), and used to represent the current view ofdoi:10.1145/1871437.1871450 dblp:conf/cikm/PiwowarskiFLR10 fatcat:6r6fmekohnbfdlsixzdbuw4eu4
