Modeling Science, Technology, and Innovation This document discusses modeling science, technology, and innovation (STI) using qualitative and quantitative data. STI models are developed in various domains to describe and predict the structure and dynamics of STI. Models help make assumptions explicit, describe systems, communicate systems, suggest interventions, and identify new questions. The document outlines opportunities for using big data, visual analytics, and computational models in STI decision making. It also announces a forthcoming special issue of Scientometrics on simulating STI processes and describes previous exhibits and forecasts related to modeling STI.
