An Ontology-Based Domain Modeling and Device Search in Smart Home
Yue Xu, Pengfei Hu, Huansheng Ning · 2018
Smart home technology has gained more and more attention in recent years as a part of internet of things, by making living environments smarter. The technology consists of deploying different sensors and actuators and making devices intelligent inside homes. Unfortunately, the heterogeneity of devices makes sharing and reusing the collected data difficult, while the complex relation among the user, device, location, and observation within the smart home has emerged new challenges in device search. Firstly, we proposed an ontology-based smart home domain model (SHOM), secondly, we proposed a device search framework in the smart home (DSF-SH), in which rule-based reasoning, ontology-based query expansion, and Tongyici Cilin-based query expansion are combined in order to overcome the limitation of keyword-based search technique, interpret the meaning of user's queries and help upper applications find available devices by working as a middleware. Finally, a prototype is developed to demonstrate the feasibility of the DSF-SHe The results show that it significantly increases the recall, the precision, and the F-score as compare to the keyword-based search technique.
