From systems to biology: A computational analysis of the research articles on systems biology from 1992 to 2013



Systems biology is a discipline that studies biological systems from a holistic and interdisciplinary perspective. It brings together biologists, mathematicians, computer scientists, physicists, and engineers, so it has both biology-oriented components and systems-oriented components. We applied several computational tools to analyze the bibliographic information of published articles in systems biology to answer the question: Did the research topics of systems biology become more biology-oriented or more systems-oriented from 1992 to 2013? We analyzed the metadata of 9923 articles on systems biology from the Web of Science database. We identified the most highly cited 330 references using computational tools and through close reading we divided them into nine categories of research types in systems biology, and found that articles in one category, namely, systems biology’s application in medical research, increased tremendously. This finding was corroborated by computational analysis of the abstracts, which also suggests that the percentages of topics on vaccines, diseases, drugs and cancers increased over time. Furthermore, we identified the most highly cited 330 authors over time. We found that before the mid-1990s, systems-oriented scientists have made the most referenced contributions, but in more recent years, biology-oriented researchers have made the most referenced contributions.
