This paper presents an approach to the evaluation of Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (AAL) e-Health platform, supporting the care of people with special needs (elderly or with health problems) thus improving their quality of life. The proposal is initially verified with the Siafu simulator in an AAL scenario where the users health is monitored with information...
This paper proposes an eHealth context management and distribution architecture with semantic features and designed for the Future Internet. A formal basis was used for managing both QoC (Quality of Context) and QoS (Quality of Service). Our approach was assessed in an experimental setting by using biomedical and environment sensors. The experiments showed that the context semantic processing detects...
This paper proposes an architecture for managing and distributing context information from an AAL (Ambient Assisted Living) environment to the cloud. The architecture, with semantic features, includes the processing of the sensed data using QoC (Quality of Context) parameters and data transport using SDN (Software-defined Networking). The experiments showed that the semantic context processing allows...
This paper presents a broad overview of Knowledge Engineering (KE). This is a research area that aims to develop methodologies, techniques and tools to support the construction of knowledge-based systems, supporting management and dissemination of knowledge. The objective of this paper is to bring together, in a single document, important definitions and concepts of KE, presenting its history, main...
This paper provides an approach to evaluating Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (AAL) environment. Lack of quality can lead assisted systems to respond inappropriately, resulting in errors related to assistance or support, or putting the user at risk. QoC assessments can improve these systems and set them to perform specific actions whenever lapses in quality...
This paper provides an approach to assessing Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (ALL) environment. Lack of quality can lead assisted systems to respond inappropriately, resulting in errors related to assistance or support, or putting the user at risk. QoC assessments can improve these systems and set them to perform specific actions whenever lapses in quality...
This paper provides an approach to evaluating Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (ALL) environment. The study presents the proposed context management architecture, which is then verified with the Siafu simulator in an ALL scenario where the user's health is monitored with information about blood pressure, heart rate and body temperature. Considering some parameters,...
