Internet of Things capability and knowledge mapping and construction method thereof

Abstract

The invention discloses an Internet of Things capability and knowledge mapping and a construction method thereof. The capability and knowledge mapping comprises a model layer and a data layer, whereinthe model layer is used as a capability ontology, comprises specification concept sets and logical relationships of the specification concept sets, and particularly comprises capability concepts, capability relationships, capability attributes, and definition domains and value domains of the capability attributes; the data layer is used as an entity set of the capability and knowledge mapping andinstantiation of the model layer, and particularly comprises capability entities, capability attribute values, relationships between capability entities, object entities, and relationships between the object entities and the capability entities. According to the Internet of Things capability and knowledge mapping and the construction method thereof, capabilities are separated to serve as core nodes of the mapping, meanwhile, the capabilities are distinguished from other attributes of objects, the capabilities can be searched rapidly and relationships between the objects can be established through the capabilities, and supports can be provided for semantic search, service composition and user recommendation in the field of the Internet of Things.

Description

technical field [0001] The invention belongs to the field of Internet of Things architecture, and in particular relates to an Internet of Things capability knowledge graph and a construction method thereof. Background technique [0002] The Internet of Things (IoT) is called a network connected to things. It integrates various information sensing devices and systems, such as sensor networks, radio frequency tag reading devices, bar code and two-dimensional code devices, global positioning systems and other A short-distance wireless self-organizing network based on the object communication mode (M2M) is a huge intelligent network formed by combining various access networks with the Internet. If the Internet realizes the communication between people, then the Internet of Things can realize the communication between people and objects, as well as the connection and interaction between objects. [0003] In recent years, the Internet of Things has developed rapidly, and the prob...
