Scientometrics has provided a gentle introduction to empower decision-makers to make sense of science, technology, and innovation data to improve daily decision.

Section 1 argues for bibliometric analysis in the study of science, technology, and innovation structure. The science of scientific publication studies and information visualization explain facts at different levels of science, technology, and innovation system.

Section 2 introduces patent analysis in the study of science, technology, and innovation structure and dynamics. Linkage between scientific publications and patents explains knowledge flows from science to technology.

Section 3 examines content-based analysis and discusses the possible impact of real-time vis‐ ualization. It includes methodology for analyzing publications based on the combination of word embedding and entropy-based approach.

Those analyses in this book are very useful for the scientometrics community.

Our sincere thanks go to Julian Virag at InTechOpen Limited who ingeniously mastered the many complexities involved in publishing the book *Scientometrics*. We are indebted to our family and friends for providing much inspiration, energy, and loving support.
