Entangling words and meaning presented by Peter Bruza Ph.D – Professor Queensland University of Technology. Concept combinations cover a broad range of compound phrases ranging from the everyday ``black cat to novel compound nominals such as ``cactus fish”. In both cognitive science and computational linguistics the prevailing view is the semantics of a concept combination are compositional, i.e., its assumed to be determined from the semantics of its constituent concepts. In the emerging field of quantum cognition several articles have speculated that concepts in human memory may sometimes behave like quantum entangled particles and hence are non-compositional phenomena. Utilising probabilistic methods developed for analysing composite systems in quantum theory, we show that it is possible to classify classify conceptual semantics on a spectrum: ``compositional, ``classically non-compositional and ``non-classically non-compositional. An empirical study of twelve bi-ambiguous concept combinations involving hundreds of human subjects revealed them to be either ``classically non-compositional or ``non-classically non-compositional.The latter classification arises from an analogy with quantum entangled systems, and offers an intriguing new perspective on the modelling of the semantics of concept combinations in a non-compositional way by means of non-factorizable joint probability distributions. Empirical data will be shown to illustrate the (non-)compositional semantics of some bi-ambiguous concept combinations."
