Fuzzy CARA - A Fuzzy-Based Context Reasoning System For Pervasive Healthcare

Bingchuan Yuan, John Herbert
2012 Procedia Computer Science  
This paper presents a fuzzy-logic based context model and a related context-aware reasoning middleware that provides a personalized, flexible and extensible reasoning framework for CARA.  ...  Noteworthy about the work is the use of fuzzy-logic to deal with the imperfections of the data, and the use of both structure and hierarchy to control the application of rules in the context reasoning  ...  To achieve that in the CARA system, we adopted a rule-based approach based on fuzzy logic for context reasoning.  ...

Context-Aware End-User Development Review

Victor Ponce, Bessam Abdulrazak
2022 Applied Sciences  
In this paper, we present our analysis of existing EUD approaches for building context-aware applications. We present a literature review of 37 screened papers obtained from research databases.  ...  One approach is end-user development (EUD)—a set of activities and development tools that considers non-software experts as application builders.  ...  The control rules follow three modes: form-based, editor-based, and advanced for using an SCL graphical editor, SCL text editor, and fuzzy logic (without SCL), respectively.  ...

Context-aware hybrid reasoning framework for pervasive healthcare

Bingchuan Yuan, John Herbert
2013 Personal and Ubiquitous Computing  
Noteworthy about the work is the use of Case Based Reasoning(CBR) to detect conditional anomalies for home automation, and the use of hierarchical Fuzzy Rule Based Reasoning(FRBR) to deal with exceptions  ...  We study how the incorporation of rule-based and case-based reasoning enables CARA to become more robust and to adapt to a changing environment by continuously retraining with new cases.  ...  In this paper we present a novel approach that combines context awareness, case-based reasoning, and general domain knowledge in a healthcare reasoning framework.  ...

A fuzzy ontology for semantic modelling and recognition of human behaviour

Natalia Díaz Rodríguez, Manuel P. Cuéllar, Johan Lilius, Miguel Delgado Calvo-Flores
2014 Knowledge-Based Systems  
As a result, we demonstrate that the inclusion of fuzzy concepts and relations in the ontology provide benefits during the recognition process with respect to crisp approaches.  ...  We provide a proof of concept of the approach in work scenarios such as the office domain, and also make experiments to emphasize the benefits of our approach with respect to crisp ontologies.  ...  We also thank Fernando Bobillo and Robin Wikström for their advice with FuzzyOWL and fuzzyDL tools.  ...
