A self-service-oriented knowledge network and its construction method

Abstract

The invention provides a knowledge network oriented to autonomous service, and a construction method thereof. The network is a knowledge network based on a flat structure. The network processes data collected by sensor nodes of an underlying network by constructing unified middle layer elements, and provides API interfaces for upper layer service to access; the middle layer elements are used for inquiring and accessing the sensor nodes based on a regional mode, and collecting data; the middle layer elements form reticular or annular structures which are on the same plane through logical connection; the upper layer application service only needs to access a certain element in the middle layer to obtain required information. The middle layer elements belong to a knowledge organization management layer which is composed of a plurality of KMC elements intercommunicated for knowledge exchange; the KMC elements are entities containing knowledge; the upper layer application service accesses the KMC elements exclusively connected with the KMC elements by calling the API interfaces; meanwhile, the KMC elements are connected with the corresponding KMC elements according to different knowledge requirements.

Description

technical field [0001] The invention relates to an autonomous network and an autonomous service, in particular to an autonomous service-oriented knowledge network and a construction method thereof. Background technique [0002] With the rapid development of computer network technology and mobile communication technology, Internet-based services have become a new trend in the development of the global information technology industry and service industry, such as traditional voice, video and other multimedia services, new e-commerce services, Financial services and online bill payment services, etc. Internet services have penetrated into all aspects of people's lives, and with the popularization of broadband and wireless networks, as well as the wide application of smart terminals represented by mobile phones and tablet computers, Internet services have become universal, simple and convenient. Advantages, and can provide users with a comprehensive, seamless and good user expe...

Problems solved by technology

In addition, this direct access method can only be applied to networks with strong sensor node capabilities and small node scale, and the supported application services are relatively simple, which cannot be adapted to distributed environments.

[0019] 2) Centralized server processing is adopted. Since the tasks of storage, calculation and transmission are all concentrated in the server, the server is likely to form a single-point bottleneck; in addition, the processing efficiency of the server will greatly affect the user experience of the service

Once there is a problem with the server, it will cause the intermediate processing process of the knowledge network to collapse, which will greatly reduce the reliability of the system

Furthermore, the centralized approach greatly affects the scalability of the system

[0020] 3) In the existing middleware structure scheme, the aggregator element and the KC element process data in a collaborative manner to provide application services, but their independent query access to sensor data causes a large amount of network connection load and consumes Sensor Resources

In terms of data storage, the KA components deployed on the sensor store multiple copies of data at the same time, which brings a large storage load to the sensor
