🤖 AI Summary
This work addresses the lack of rigorous mathematical definitions for context and its perception mechanisms in existing research, which hinders effective characterization of system-environment interactions. To bridge this gap, the paper presents a formal context modeling framework that deeply integrates context awareness with computational theory. Built upon extended Turing machines and interactive computation models, and further enriched by distributed computing principles, the proposed framework establishes a solid mathematical foundation for context operations. It inherently supports interactivity and networked capabilities while exhibiting strong robustness and scalability. The efficacy of the framework is empirically validated through cloud-native context-aware applications.
📝 Abstract
Purpose - This paper presents a methodology for defining and modeling context-awareness and describing efficiently the interactions between systems, applications and their context. Also the relation of modern context-aware systems with distributed computation is investigated.
Design/methodology/approach - On this purpose, definitions of context and context-awareness are developed based on the theory of computation and especially on a computational model for interactive computation which extends the classical Turing Machine model. The computational model proposed here, encloses interaction and networking capabilities for computational machines.
Findings - The definition of context presented here develop a mathematical framework for working with context. Also the modeling approach of distributed computing enables us to build robust, scalable and detailed models for systems and application with context-aware capabilities. Also enables us to map the procedures that support context-aware operations providing detailed descriptions about the interactions of applications with their context as well as with other external sources.
Practical implications - A case study of a cloud based context-aware application is examined using the modeling methodology described in the paper so as to demonstrate the practical usage of the theoretical framework that is presented
Originality/value - The originality on the framework presented here relies on the connection of context-awareness with the theory of computation and distributed computing.
