Ontology‐Based Framework for the Automatic Recognition of Activities of Daily Living Using Class Expression Learning Techniques

Scientific Programming, Volume 2019, Issue 1, 2019., 2019
The miniaturization and price reduction of sensors have encouraged the proliferation of smart environments, in which multitudinous sensors detect and describe the activities carried out by inhabitants. In this context, the recognition of activities of daily living has represented one of the most developed research areas in recent years.

A Review of Semantic Sensor Technologies in Internet of Things Architectures

Complexity, Volume 2019, Issue 1, 2019., 2019
Intelligent sensors should be seamlessly, securely, and trustworthy interconnected to enable automated high‐level smart applications. Semantic metadata can provide contextual information to support the accessibility of these features, making it easier for machines and humans to process the sensory data and achieve interoperability.

SmartOntoSensor: Ontology for Semantic Interpretation of Smartphone Sensors Data for Context‐Aware Applications

Journal of Sensors, Volume 2017, Issue 1, 2017., 2017
The integration of cheap and powerful sensors in smartphones has enabled the emergence of several context‐aware applications and frameworks. However, the available smartphone context‐aware frameworks are static because of using relational data models having predefined usage of sensory data.

SREQP: A Solar Radiation Extraction and Query Platform for the Production and Consumption of Linked Data from Weather Stations Sensors

Journal of Sensors, Volume 2016, Issue 1, 2016., 2016
Nowadays, solar radiation information is provided from sensors installed in different geographic locations and platforms of meteorological agencies. However, common formats such as PDF files and HTML documents to provide solar radiation information do not offer semantics in their content, and they may pose problems to integrate and fuse data from ...

SensorML profiles and O&M data models adapted to specific marine observation data. SensorML and O&M expressions for Research Vessels and Fixed Stations.

, 2014
SeaDataNet II wants to adopt the OGC standards for Sensor Web Enablement (SWE). This document formulates specific SeaDataNet profiles for the SensorML and Observations & Measurements models that can be applied by operators of operational observation systems to describe in more detail their observations and to provide standardised access to these ...

Análise de Desempenho de Catálogo de Produtores de Dados para Internet das Coisas baseado em SensorML e NoSQL

Anais do XIV Workshop em Desempenho de Sistemas Computacionais e de Comunicação (WPerformance 2015), 2015
O advento da Internet das Coisas permitiu o desenvolvimento de sistemas mais inteligentes nos quais “coisas” e objetos do mundo real podem trocar informação entre si. A quantidade de participantes de um sistema deste tipo é potencialmente massiva. Desta forma, torna-se imprescindível a existência de um catálogo para viabilizar serviços de publicação e ...
