Quantum Logic of Semantic Space: An Exploratory Investigation of Context Effects in Practical Reasoning

Bruza, Peter D. & Cole, Richard (2005) Quantum Logic of Semantic Space: An Exploratory Investigation of Context Effects in Practical Reasoning. In Artemov, S., Barringer, H., d'Avila Garcez, A.S., & Woods, J.H. (Eds.) We Will Show Them: Essays in Honour of Dov Gabbay. College Publications, London, UK, pp. 339-361.


This article is an exploratory account of the the non-monotonic behaviour of conceptual associations in the light of context. Computational approximations of conceptual space are furnished by semantic space models which are emerging from the fields of cognition and computational linguistics. Semantic space models not only provide a cognitively motivated basis to underpin human practical reasoning, but from a mathematical perspective, they are real-valued Hilbert spaces. This introduces the highly speculative prospect of formalizing aspects of human practical reasoning via quantum mechanics. This account focuses on how to formalize context effects in relation to concepts as well as keeping an eye on operational issues.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
