Such an exponential rise in the use of the World Wide Web due to social networks started to fetch huge volume of data across diverse domains in short period of time.
Since the use of big data analytical techniques in many domains have obtained remarkable improvements in the way various businesses operate, we consider that social network domain is not an exception to this perception.
The analysis of structured and unstructured data from social networks leads to social network analytics.
Objectives: The aim of this special issue is to promote research in social network analysis by using various machine learning techniques.
This will lead to the development of new and improvised applications in various domains such as business, product development/improvement, political, social reformation, other services etc.

Key factors in these developments were: • The invention of the steam machine in 1769 and the utilization of coal for drive.
• Construction of an internal combustion engine in the 19 century, which contributed to the rapid development of motor transportation and the increase in fuel consumption.
• The discovery of large natural gas deposits, which were used as fuel and raw chemical materials. Energy sectors worldwide, including the Polish energy sector, stand currently in front of large challenges.
