birddog: Sniffing Emergence and Trajectories in Academic Papers and
Patents
Provides a unified set of methods to detect scientific emergence
and technological trajectories in academic papers and patents. The package
combines citation network analysis with community detection and attribute
extraction, also applying natural language processing (NLP) and structural
topic modeling (STM) to uncover the contents of research communities. It
implements metrics and visualizations of community trajectories, including
novelty indicators, citation cycle time, and main path analysis, allowing
researchers to map and interpret the dynamics of emerging knowledge fields.
Applications of the method include: Souza et al. (2022)
