Examining the characteristics of impactful research topics: A case of three decades of HIV-AIDS research

作者：

Highlights：

• We collected metadata of three decades of HIV-AIDS research from Scopus.

• We constructed dynamic topic networks from their abstracts using topic modeling.

• Topics in high-impact studies are novel, vary in maturity, face little competition.

• Higher impact studies also involve a smaller number of topics.
