Linking and establishing correlation among multiple open data sets

摘要

Recent years have witnessed appreciable number of open data sets availed to the public domain. This thesis therefore intends to find the association among multiple linked open data sets by establishing the correlation among them with comparison to the analysis of single data sets.Open weather data from Modern Era Retrospective – Analysis for Research and Applications (MERRA), electricity production data and electricity consumption data, both data sets from Lappeenranta University of Technology (LUT) are used in this study.Based on the results, it is found that linking and analysis of multiple open data sets is more informative as compared to the analysis of single data sets. This is seen from the weather parameters which are found to correlate with electricity production data set.
