Nuclear energy is one of controversial topics that affects people’s lives, and it is important for policy makers to analyze what people feel towards the subject. But manual analysis of related user-generated contents on social media platforms is a daunting task, and automatic data analysis and visualization come to help. So, in this research, we firstly developed a model for classifying the emotion of nuclear energy related tweets and another model for the aspect-based sentiment analysis of nuclear energy tweets using the BERT (Bidirectional Encoder Repre- sentations from Transformers). After that, we developed a prototype system for visualization of the analyzed results stored in the database. The user interface dash- boards of the system allow users to monitor emotion and sentiment trends towards nuclear energy by analyzing recent nuclear energy tweets crawled weekly. Keywords: Emotion analysis · Aspect based sentiment classification · Deep learning · BERT · Nuclear energy 1 Introduction Social media have served as the digital mediator to share and exchange ideas and infor- mation to a larger audience [6]. And Twitter is one of trending social media platforms in the current era when it comes to opinionating people’s choices. Therefore, automatic analysis of user-generated content on platforms like Twitter help relevant organizations not only to understand people’s emotions and opinions on the diverse aspects of target subjects but also to make effective decisions. Energy has been harnessed by humans for millennia. Especially, nuclear energy is a seriously disputed topic that has been on the ground for years. Though there are various types of power plants arising across the globe, some governments are building nuclear power plants for better power supply, yet diverse groups of people have different opinions © Springer Nature Switzerland AG 2021 H.-R.
