Scientific progress, at its core, is about constant change. Progress is brought about by introducing new findings where there were none, altering previously established knowledge, and in some cases, deconstructing prior knowledge to replace it with new findings. This process happens, generally, through scientific publications; in journals, at conferences, at workshops, in articles. Thus it is possible to analyze these documents and see how knowledge would change with time. This study accomplishes said task in the domain of MicroRNA which is a subdomain of Medical Science. Research paper abstracts are taken from an online medical research database and are analyzed to notice any changes in paradigms, ideas or claims.
