A quantitative framework for revealing disciplinary organizations of science

Abstract: Quantitative measurement is the cornerstone of scientific advancement. Here we present a framework for facilitating quantitative inquires about scientific disciplines. We adapt a popular word embedding technique to the data of scholarly citation trails among 53 million scientific papers to learn continuous vector-space representation of scientific venues. We obtain a high dimensional map of science from the learnt embeddings. Our map reveals the disciplinary organizations of science as exemplified in the direction and the spectrum of science by allowing arithmetic operations between venue vectors. Vector representations of scientific venues also facilitate downstream applications such as recommending similar venues and predicting discipline categories.
