Title: Build Up of a Subject Classification System from Collective Intelligence
Abstract: Systematized subject classification is essential for funding and assessing scientific projects.Conventionally, classification schemes are founded on the empirical knowledge of the group of experts; thus, the experts' perspectives have influenced the current systems of scientific classification.Those systems archived the current state-of-art in practice, yet the global effect of the accelerating scientific change over time has made the updating of the classifications system on a timely basis vertually impossible.To overcome the aforementioned limitations, we propose an unbiased classification scheme that takes dvantage of collective knowledge; Wikipedia, an Internet encyclopedia edited by millions of users, sets a prompt classification in a collective fashion.We construct a Wikipedia network for scientific disciplines and extract the backbone of the network.This structure displays a landscape of science and technology that is based on a collective intelligence and that is more unbiased and adaptable than conventional classifications.
