Knowledge Management System for Semantic Sensor Data [Anlamsal Sensor Verileri Icin Bilgi Yonetim Sistemi]

The increasing number of wireless sensor networks, which are used extensively in industrial areas, has led to a tremendous increase in the data obtained from the sensors. This uncontrolled increase makes it difficult for managing and storing of data. Moreover, the lack of infrastructure to ensure the integrity of meaning between the data makes it impossible to share, reuse and interpret the data by machines. These inabilities can cause some problems like cannot managing together between separate wireless sensor networks due to the subtle variations in their sensing methods, operating systems, syntax, and data structure. To address all these problems, a semantic sensor network approach has been introduced which provides a common standard for sensor data and aims to enhance their meaning. In this study, semantic model with realworld usage from sensor networks measuring some laboratory parameters is proposed. In order to evaluate the proposed system, a series of semantic queries were prepared and applied to the obtained sensor data. The results show that sensor data can be managed on a common infrastructure using ontologies. © 2020 IEEE.
