My focus has been on developing semantic technologies for the representation, management, and interpretation of sensor data, both on the Web and on resource-constrained devices (such as smart phones). Among other exiting applications, this technology is currently being used within an mHealth application to monitor and manage chronic diseases, such as heart failure and asthma. | |

+ | ===Semantic Sensor Web=== | ||
+ | Millions of sensors around the globe currently collect avalanches of data about our environment. The rapid development and deployment of sensor technology involves many different types of sensors, both remote and in situ, with such diverse capabilities as range, modality, and maneuverability. It is possible today to utilize networks with multiple sensors to detect and identify objects of interest up close or from a great distance. The lack of integration and communication between these networks, however, often leaves this avalanche of data stovepiped and intensifies the existing problem of too much data and not enough knowledge. With a view to alleviating this glut, we propose that sensor data be annotated with semantic metadata to provide contextual information essential for situational awareness. In particular, Semantic Sensor Web is a framework for managing heterogeneity among sensor descriptions and sensor observation data through semantic modeling and annotation to enable advanced Web-based data integration, query, and inference. This project has helped to initiate a W3C Incubator Group, the Semantic Sensor Network XG, and develop a standard ontology and semantic annotation framework. These tools are achieving broad adoption and application within the sensing community for managing sensor data on the Web. [http://knoesis.org/projects/ssw/ SSW Project] | ||

As perceptual beings, we are also constantly inundated with sensory data; yet we are able to make sense out of our environment with relative ease. Semantic Perception is a computational framework, inspired by cognitive models of human perception, to derive actionable intelligence and situational awareness from low-level sensor data. The formalization of this ability utilizes prior knowledge encoded in domain ontologies, and hybrid abductive/deductive reasoning, to translate low-level observations into high-level abstractions. A declarative specification defined in OWL allows prior knowledge available on the Web, and annotated with Semantic Web languages, to be easily integrated into the framework. |

+ | ===Intelligence at the Edge=== | ||
+ | Intelligence at the Edge is a framework that enables efficient and scalable execution of machine perception on resource-constrained devices, such as mobile phones and gateway nodes, by downscaling semantic processing. This is accomplished through the use of bit-vector encodings and operations to efficiently represent domain knowledge and implement the semantic perception algorithms. This approach has demonstrated dramatic order-of-magnitude improvements in both efficiency and scale, with run-time execution reduced from minutes to milliseconds, problem size (i.e., allowable size of domain ontology) increased from tens of concepts to thousands, and computational complexity reduced from polynomial to linear. | ||

− | + | kHealth – Knowledge-enabled Healthcare is a platform which integrates data from passive and active sensing (including both machine and human sensors) with background knowledge from domain ontologies, semantic reasoning, and mobile computing environments to help people make decisions to improve health, fitness, and wellbeing. kHealth utilizes technology from Semantic Sensor Web, Semantic Perception, and Intelligence at the Interface to enable advanced healthcare applications. Currently we are developing an app with OSU to reduce preventable hospital readmissions of patients with Acute Decompensated Heart Failure. [http://knoesis.org/projects/khealth kHealth Project] | |

Latest revision as of 13:21, 27 June 2016
Semantic Web researcher at the Kno.e.sis Center, Ph.D. candidate at Wright State University (with advisor Amit Sheth), and research staff member at Riverside Research. My focus has been on developing semantic technologies for the representation, management, and interpretation of sensor data, both on the Web and on resource-constrained devices (such as smart phones). Among other exiting applications, this technology is currently being used within an mHealth application to monitor and manage chronic diseases, such as heart failure and asthma.
While completing a Ph.D. in Computer Science, I also act as project lead for the Semantic Sensor Web and editor for the W3C Semantic Sensor Network Incubator Group.

Semantic Sensor Web
Millions of sensors around the globe currently collect avalanches of data about our environment. The rapid development and deployment of sensor technology involves many different types of sensors, both remote and in situ, with such diverse capabilities as range, modality, and maneuverability. It is possible today to utilize networks with multiple sensors to detect and identify objects of interest up close or from a great distance. The lack of integration and communication between these networks, however, often leaves this avalanche of data stovepiped and intensifies the existing problem of too much data and not enough knowledge. With a view to alleviating this glut, we propose that sensor data be annotated with semantic metadata to provide contextual information essential for situational awareness. In particular, Semantic Sensor Web is a framework for managing heterogeneity among sensor descriptions and sensor observation data through semantic modeling and annotation to enable advanced Web-based data integration, query, and inference. This project has helped to initiate a W3C Incubator Group, the Semantic Sensor Network XG, and develop a standard ontology and semantic annotation framework. These tools are achieving broad adoption and application within the sensing community for managing sensor data on the Web. SSW Project

Semantic approach to Machine Perception
Currently, there are many sensors collecting information about our environment, leading to an overwhelming number of observations that must be analyzed and explained in order to achieve situation awareness. As perceptual beings, we are also constantly inundated with sensory data; yet we are able to make sense out of our environment with relative ease. Semantic Perception is a computational framework, inspired by cognitive models of human perception, to derive actionable intelligence and situational awareness from low-level sensor data. The formalization of this ability utilizes prior knowledge encoded in domain ontologies, and hybrid abductive/deductive reasoning, to translate low-level observations into high-level abstractions. A declarative specification defined in OWL allows prior knowledge available on the Web, and annotated with Semantic Web languages, to be easily integrated into the framework.

Intelligence at the Edge
Intelligence at the Edge is a framework that enables efficient and scalable execution of machine perception on resource-constrained devices, such as mobile phones and gateway nodes, by downscaling semantic processing. This is accomplished through the use of bit-vector encodings and operations to efficiently represent domain knowledge and implement the semantic perception algorithms. This approach has demonstrated dramatic order-of-magnitude improvements in both efficiency and scale, with run-time execution reduced from minutes to milliseconds, problem size (i.e., allowable size of domain ontology) increased from tens of concepts to thousands, and computational complexity reduced from polynomial to linear.

kHealth - Knowledge-enabled Healthcare
kHealth – Knowledge-enabled Healthcare is a platform which integrates data from passive and active sensing (including both machine and human sensors) with background knowledge from domain ontologies, semantic reasoning, and mobile computing environments to help people make decisions to improve health, fitness, and wellbeing. kHealth utilizes technology from Semantic Sensor Web, Semantic Perception, and Intelligence at the Interface to enable advanced healthcare applications. Currently we are developing an app with OSU to reduce preventable hospital readmissions of patients with Acute Decompensated Heart Failure. kHealth Project
