Problems solved by technology

In the absence of relevant quality indicators, the existing context-aware systems directly use the original context information without uncertainty processing, which may lead the system to make inappropriate reasoning decisions, which in turn affects the system's service quality and user satisfaction.

Embodiment 1

[0086] A contextual uncertainty elimination system based on hierarchical comprehensive quality index QoX, such as figure 1 As shown, it includes context acquisition layer, context processing layer, application layer connected in sequence,

[0087] The context acquisition layer is used to: as the sense of the entire context awareness system, periodically collect original context information through multiple physical sensors, virtual sensors and logical sensors, and send the collected original context information to the context processing layer; the original context is The unprocessed context information collected by various sensors mainly includes environment context, device context, user context and time context information;

[0088] The context processing layer is used to: as the core of the entire context awareness system, perform uncertainty elimination and fusion reasoning on the original context information acquired by the context acquisition layer according to various pr...

Embodiment 2

[0110] The present invention is a context uncertainty elimination system based on a hierarchical comprehensive quality index QoX in an intelligent perception space, which can effectively improve the efficiency and accuracy of context uncertainty elimination, so as to meet the real-time and self-adaptive requirements in actual context-aware computing applications The requirements of precision and precision can improve the overall performance of the system. The method of the embodiment of the present invention, its flow process is as follows figure 2 Shown:

[0111] Take the typical scenario of context-aware computing—smart home as an example. In the smart home, four methods of WIFI, Bluetooth, infrared and Zigbee are used to collect the location information about the user. The scene information obtained by WIFI, Bluetooth, infrared and Zigbee is I WIFI , I 蓝牙 , I 红外 , I Zigbee ,Specific steps are as follows:

[0112] S01: Calculate and analyze user preference QoE, includ...

Abstract

The invention relates to a context uncertainty elimination system based on a hierarchical comprehensive quality index QoX and a working method thereof. The system includes a context collection layer, a context processing layer and an application layer. In the present invention, quality indicators such as collection equipment quality, context information quality, system service quality, and user experience quality are used as hierarchical comprehensive quality indicators QoX, and integrated into the context-aware system to provide context uncertainty elimination in context-aware computing. It is an effective method. At the same time, users and the system can actively adjust various preset thresholds and rules according to their own needs and changes in environmental conditions, which makes our system more reliable and adaptable.

Description

technical field [0001] The invention relates to a context uncertainty elimination system based on a hierarchical comprehensive quality index QoX and a working method thereof, belonging to the application field of context-aware computing. Background technique [0002] With the rapid development of network technology, people are more and more aware that the future network not only needs to be fast and ubiquitous, but also needs the support of more advanced technologies. Among them, the most important thing is to have the ability to realize smart services. In order to realize this capability, related technologies such as ubiquitous computing, cooperative computing, intelligent computing and virtual reality have emerged. What these technologies have in common is that they all need context awareness as "tentacles" to perceive the changing surrounding environment. [0003] The goal of ubiquitous computing is to realize the organic integration of information space and physical sp...
