Analysis of the Trends in Biochemical Research Using Latent Dirichlet Allocation (LDA) [PDF]

open access: yesProcesses, 2019
Biochemistry has been broadly defined as “chemistry of molecules included or related to living systems”, but is becoming increasingly hard to be distinguished from other related fields. Targets of its studies evolve rapidly; some newly emerge, disappear, combine, or resurface themselves with a fresh viewpoint.
