This phase is referred as Industry 4.0. With Industry 4.0, companies are working to take advantage of information technology to increase profitability and productivity. Increasing use of social media in recent years has forced companies to show their presence on those platforms. Social media is a major source of meaningful information for companies because it contains large amounts of data. In this study, the top five companies operating in information technology (IT) research/consulting and the top five companies operating in enterprise resource planning (ERP) field were selected. Conclusions have been made based on the analysis of the tweets related to Industry 4.0.展开更多
