Radical Innovation – Create, Adapt, Co-operate or Centralize

“We are searching for an innovation policy that promotes growth – but we cannot conclude, before further evidence, that this policy must be related to radical innovations, however defined.”

The above qoute was written by Staffan Laestadius during the writing of RAID projects first policy brief. I highlighted it as it works well as an introductory to our policy brief that strives towards having a dialoque on what is the link between radical innovations and growth.

Our projects first policy brief, now published, focused on defining and fine-tuning the content of the project. In the brief, we focus on three themes “Create or adapt – the cycle of endogenous and exogenous learning”, “Co-operation is not the silver bullet” and “Centralized or decentralized” through which we offer vantage points to support dialogue among policy makers and scholars.

The policy brief was published by Tekes and is openly available at the Tekes webpage

Map of Science using Topic Modeling

For a long time, we ha relied different library classifications to measure the science output of nations, organizations or individuals. Journal classification, co-citations and/or co-word approaches have all been used to structure and visualize the maps of science. Most notable effort in visualizing what we know has been made by Professor Katy Börner in creating the “Atlas of Science, based on the popular exhibit, Places & Spaces: Mapping Science”

We made an effort to move beyound existing methods of visualization and take advantage on the advancements in machine learning – arguing that we could understand far better what we know if we would create the atlas of science based on what was actually written rather than how the written word has been classified.

Below is a D3.js based quick and dirty rendering of the visuals in our publication titled Map of Science using Topic Modeling published in the Journal of the Association for Information Science and Technology. The quick and dirty visual uses the example in emeeks’s block #9357371 of rendering a GEFX, created in this instace in Gephi, to D3.js. Much of course could be improved to take full advantage of the example, but that has to remain as future work. However, already this visual gives you the opportunity to zoom and select on different nodes in the figure provided as a static picture in the article.

A few words on policy relevance

In writing the article, we discovered that our maps could be particularly useful in looking at organization level specializations and temporal dynamics. This is timely, as we have heard several calls for more detailed measurement of university and research output – not just counts – and as we can only see significantly diminishing government funding in the future. Not visualized here, but easily produced are maps of individual universities. This might be useful for policy making?

Operating the Map

You can interact with the map below. Use these simple functions

  • Using your mouses scroll-wheel (or zoom function in your keyboard) you can zoom in or out in the figure.
  • You can also drag the figure by pressing down your mouse button and draggin graph in the frame.
  • You can click on a node to see its label and connections.
  • From the buttons below you can reset the graph if needed.
