Internet of Things terminal interoperation method and device based on semantic comprehension

Abstract

The invention discloses an Internet of Things terminal interoperation method and device based on semantic comprehension, and relates to the field of the Internet of Things and the Internet. The method comprises the following steps that: according to an internal knowledge base, an external knowledge base and Internet data contents, obtaining each entity oriented to an Internet of Things application and the name of each entity in the Internet; calculating the correlation of all entities, and forming a uniform named entity name which aims at the same entity; carrying out semantic extension on each entity and the operation function of each entity; when an Internet of Things request is received, through Internet of Things entity semantic calculation, determining the named entity name and an operation function corresponding to the Internet of Things request; when a certain operation is finished, recording and evaluating a current operation and task finishing situation; and according to the situation, carrying out back annotation on each entity which realizes the operation functions for obtaining the combination of optimal entities which realize the Internet of Things request when a relevant task or operation request is in the presence in the future. Therefore, an equipment interoperation problem under different protocol standard systems can be solved.

Description

technical field [0001] The present invention relates to the fields of the Internet of Things and the Internet, in particular to a method and device for interoperating terminals of the Internet of Things based on semantic understanding. Background technique [0002] The Internet of Things uses technologies and equipment such as two-dimensional codes, radio frequency identification (RFID), and various sensors / sensitive devices to connect objects to various networks such as the Internet to obtain ubiquitous information in the real world, and to realize the connection between objects and objects. Information interaction with people supports intelligent informatization applications, realizes the comprehensive integration of information infrastructure and physical infrastructure, and finally forms intelligent infrastructure. In essence, the Internet of Things is a networked application and communication capability built on the network. [0003] Natural Language Processing (NLP), ...

AI Technical Summary

Problems solved by technology

[0009] Defect 1: Artificial construction is not suitable for the application of the massive information of the Internet of Things

These ontologies describe the basic concepts of the Internet of Things in a coarse-grained manner, but limited by the speed of artificial construction and the rapid development of Internet of Things technology, these ontologies lack descriptions of specific system features and emerging concepts, and are not suitable for different IoT The mutual coordination between networked systems completes a new task, and it is impossible to carry out integrity labeling with strong adaptability to equipment

[0010] Defect 2: It is more inclined to logical theory, and farther away from the existence of the world

[0011] Deficiency 3: The establishment of ontology is to borrow the ontology concept in natural language processing, which refers to the method of determining the abstract name and function of an entity in the information from the background and purpose of generation, but there is no context similar to natural language understanding at present, because Differences in background and knowledge levels are not suitable for different external users

[0012] Defect 4: Terminals built for different purposes are difficult to be called by other tasks; or similar terminals (or the same terminal) built by different organizations are difficult to be used by outside organizations (outside the industry) due to differences in descriptions. used by users, it is difficult to gather together to complete a new task
