About this subject

This page presents an analysis of topic network isolation on GitHub, a metric that highlights how connected or distinct specific subject areas are. We've developed a method to quantify the average isolation score for each topic, indicating how often repositories tagged with a given topic also use a wide range of other, unrelated topics.

We also measure the median topic connectivity, which gives a general sense of how integrated the broader topic landscape is. This data is derived from analysing the co-occurrence of topics across millions of GitHub repositories. Understanding this network helps reveal the structure of software development interests and the boundaries between different communities of practice.

This information is particularly valuable for developers, researchers, and anyone interested in the landscape of open-source development. It offers a unique perspective on how topics cluster and diverge, a complex analysis that is rarely made public.
