Map of Science using Topic Modeling

oecd_to_tm_croppedLooked at, with Hannes Toivanen, if we could visualize science production using Topic Modeling. We know that

from theoretical and practical perspectives there exist several challenges for human reasoning-based classification frameworks of scientific knowledge, as they typically try to fit new-to-the-world knowledge into historical models of scientific knowledge, and cannot easily be deployed for new large-scale data sets. Automated classification schemes, in contrast, generate classification models only from the available text corpus, thereby identifying credibly novel bodies of knowledge. They also lend themselves to versatile large-scale data analysis, and enable a range of Big Data possibilities.

So, there might be an added value to our approach compared to main stream methods.

Our work is now in Early View in the Journal of the Association for Information Science and Technology and we made it Open Access.
