What is tech mining?

Tech mining is the process of generating valuable technological competitive intelligence from ST&I literature resources using bibliometrics, text mining, and other visualization tools ( Guo et al., 2015; A. Porter, 2007; A. L. Porter and Newman, 2009 ). It seeks to enhance understanding of technology dynamics in every aspect of the R&D process.
