Abstract

Permanent repository link AbstractThe use of quantum concepts and formalism in the information sciences is assessed through an analysis of published literature. Five categories are identified: use of loose analogies and metaphors between concepts in quantum physics and library/information science; use of quantum concepts and formalisms in information retrieval; use of quantum concepts and formalisms in studying meaning and concepts; quantum social science, in areas adjacent to information science; and the qualitative application of quantum concepts in the information disciplines. Quantum issues have led to demonstrable progress has been made in information retrieval and semantic modelling, with less clear cut progress elsewhere. Whether there may be a future 'quantum turn' in the information sciences is debated, the implications of such a turn considered, and a research agenda outlined. IntroductionOver a period of many years, and with increasing frequency in the past decade, quantum concepts have appeared in the literature of the social sciences in general, and the library/information sciences (LIS) in particular. This manifestation has taken several forms. Many have been passing mentions: loose analogies and empty metaphors. Some have applied a mathematical formalism, sometimes with a clear justification, sometimes just because it works. Some have used detailed and rich metaphors and analogies, linking concepts from the physical world with the social and informational realm, and some have claimed that such a linkage is 'real'. Others have argued that there is a general intellectual movement, a zeitgeist, centred around quantum concepts, and that the social sciences, including LIS, should partake in this.

Still Minding the Gap? Reflecting on Transitions between Concepts of Information in Varied Domains

“…Interest in, and use of, information concepts, and Shannon's information theory in particular, within the physical sciences have continued to increase and have been reviewed from the perspective of gap-bridging [12][13][14][15].…”
