Abstract

The invention discloses an ontology construction method based on semantic Internet of Things. The method comprises the steps of obtaining an Internet of Things database, traversing the Internet of Things database, judging whether at least two semantic tables exist or not, if yes, judging whether the at least two semantic tables have the same main key or not, if yes, merging one semantic table of the at least two semantic tables and all different items in the other semantic tables into each semantic table, deleting one of the semantic tables from the Internet of Things database to form a new Internet of Things database, traversing each of all semantic tables in the updated Internet of Things database to judge whether all keys in the updated Internet of Things database are external keys or not, and determining that the number of other semantic tables pointed by the semantic table is at least two, and the other semantic tables pointed by the semantic table do not exist. According to the present invention, the technical problem that the development of the Internet of Things technology is hindered due to the heterogeneity of data representation in the existing Internet of Things, can besolved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and more particularly, relates to a method and system for constructing an ontology based on the semantic Internet of Things. Background technique [0002] Ontology is a description of the entities (such as people or things) in the real world, the events involved in the entities, and the relationships between entities. People can query the objects described by the ontology in the ontology. [0003] The Internet of Things has the characteristics of reliability in transmitting information, perceptibility of obtaining object information anywhere, and intelligence in data analysis and processing, that is, various areas provide the main body, and then use RFID readers to scan the tags of the items, and the item information It can be uploaded to the Internet, and the encoding only realizes the standardization of the format of the item information, but does not stipulate the standardizatio...
