Survey of Semantics for Internet of Things
Yuan Ling-yu · 2014
Information Sensing provides the information sources for the Internet of Things(IOT),and it regarded as the basis of information collaboration in IOT.But the primitive sensing information by the sensing devices in IOT is always uncertain,magnanimous and heterogeneous,which not only brings the challenges in information transmission,storage and processing for the restrained sensor network,but also increases the difficulty in information presentation and management.Semantic technology has provided a new idea for this problem.In this paper,we have expounded that semantics is applied to IOT.Firstly,semantic requirements at different levels in IOT are analyzed.Then,the application researches of semantics for IOT are described and analyzed,including semantics-based resource description and modeling,sensor data presentation and processing,semantic annotation for sensor data,service building and providing,and sensor data storage and query for IOT.Finally,some future prospects of the challenges and research directions are given.
