“…LBD seeks to infer novel, credible, and informative knowledge by explicitly or implicitly associating two or more disparate literature concepts (Bruza and Weeber, 2008 ; Ittipanuvat et al, 2014 ). Its benefits have been pursued by bibliometric researchers and applied for a variety of practical issues, especially in biomedical domains, such as the exploration of potential treatments or gene candidates for diseases (Kostoff et al, 2018 ; Wu et al, 2020 ) and uncovering new therapeutic uses for existing drugs (Ding et al, 2013 ). However, despite high potentials in interdisciplinary research (Small, 2010 ), LBD still entails a set of problem-driven and/or domain-specific approaches.…”
