A Novel Method for Big Data Analytics and Summarization based on Fuzzy Similarity Measure

The use of Internet of Things (IoT) sensors and devices is on a sharp rise with the help of infrastructures like 5G cellular networks. However, with this swift expansion come major challenges such as management of the vast data collected by these IoT devices. In the paper, we propose a method which takes advantage of fuzzy similarity to significantly simplify the big data analysis and management for human operators and machines. A use case in the area of smart buildings was utilized to illustrate its potential application. A comparison is made between the ideal situation and the data collected from an office room. The considered environmental factors in this research are temperature, humidity, and workplace lighting and then the collected data was utilized to make triangular fuzzy numbers and after that, we compare them with an efficient fuzzy similarity measure. In addition to data summarization and abstraction, this method also protects the main information from inaccuracy. The advantage of the fuzzy controlling system is its aptitude to deal with nonlinearities and uncertainties.
