【 摘 要 】

This opinion paper reviews progress with the quantum similarity model (QSM), which was proposed by Pothos et al. (2013). In the QSM, concepts are associated with subspaces, the mental state is a state vector in a Hilbert space, and similarity between two concepts is computed in terms of the sequential projection, between the corresponding subspaces. If there is a relevant context, this is incorporated as prior projections (e.g., Figure ​Figure11).
