Lexicon approach for risk analysis in emerging technologies

This article proposes a novel methodology to analyze risks in digital currencies. It depends on the perceptions of users in social media to recognize and estimate the potential risks. Besides, it includes utilizing high-level computational techniques such as big data analysis techniques and natural language processing. We illustrate the suggested system mathematically and some important expressions for risk analysis, risk recognition and risk estimation are driven in closed forms. Moreover, we present a use case study to extract insights about the potential risks related to digital currencies. Further, some indicators are provided to illustrate the effectiveness of the suggested approach like the mean accuracy for processes of analyzing risks, identifying risks and assessing risks assessment that is 77 %.
