Inspired by a quantum mechanical formalism to model concepts and their disjunctions and conjunctions, we put forward in this
paper a specific hypothesis. Namely that within human thought two superposed layers can be distinguished: (i) a layer guided by an underlying classical deterministic process, giving rise to essentially logical thought and its indeterministic version modeled by classical probability theory; (ii) a layer guided by ...

In this paper we propose a human-centered process for knowledge discovery from unstructured text that makes use of Formal Concept Analysis and Emergent Self Organizing Maps. The knowledge discovery process is conceptualized and interpreted as successive iterations through the Concept-Knowledge (C-K) theory design square. To illustrate its effectiveness, we report on a real-life case study of using the process at the Amsterdam-Amstelland police ...

In this paper, we propose an expert system for iterative requirements engineering using Formal Concept Analysis. The requirements engineering approach is grounded in the theoretical framework of C–K theory. An essential result of this approach is that we obtain normalized class models. Compared to traditional UML class models, these normalized models are free of ambiguities such as many-to-many, optional-to-optional or reflexive associations ...

This essay also draws from inquiries in epistemology, systems theory, and evolutionary biology to examine the concept of repetition as a creature of difference. Here, repetition recasts traditional concepts of difference, identity, and change. Thus it should be no surprise that the work of Gilles Deleuze is a key reference. French philosopher Gilles Deleuze had perhaps gone furthest in endowing the problem of repetition with a measure of the ...

We analyze the meaning of the violation of the marginal probability law for situations of correlation measurements where entanglement is identified. We show that for quantum theory applied to the cognitive realm such a violation does not lead to the type of problems commonly believed to occur in situations of quantum theory applied to the physical realm. We briefly situate our quantum approach for modeling concepts and their combinations with ...

The mathematical formalism of quantum theory has been successfully used in human cognition to model decision processes and to deliver representations of human knowledge. As such, quantum cognition inspired tools have improved technologies for Natural Language Processing and Information Retrieval. In this paper, we overview the quantum cognition approach developed in our Brussels team during the last two decades, specifically our identification ...

The essays in this volume explore the theories and practices of sovereignty in the context of state-building in the early modern Northern and Southern Low Countries. The Dutch Revolt, the secession of the northern provinces from the Spanish empire, the formation of the Dutch Republic and the reconstitution of Habsburg authority in the south, fostered tense debates among scholars and political leaders about the legitimacy, organisation and ...
