I’d love to see topic discovery and link suggestion in org-roam; I’ve gotten used to something similar in Evernote, and I know I’ll miss it after I take the final leap. Also, in case I’m not the only one who wasn’t aware of this, Hugo Cisneros posts his org-roam Notes in a [graph displaying edge cardinality and topic clustering](https://hugocisneros.com/notes/). ---

> [@tecosaur](#): > > which means to do this in elisp we’d more or less have to write a network science library I think with what happened with [GitHub - org-roam/org-roam-server: A Web Application to Visualize the Org-Roam Database](https://github.com/org-roam/org-roam-server), the introduction of [GitHub - org-roam/org-roam-ui: A graphical frontend for exploring your org-roam Zettelkasten](https://github.com/org-roam/org-roam-ui), org-roams built-in graphing abilities and generally users desire for better options in discovering and exploring their ZK, I would think that a standalone library that takes care of a bunch of useful algorithms like this could be justified. In then end the algorithms return org-nodes or their connections, but it would be worth communicating with the above projects what such algorithms can actually give them like the OP started doing, and coming up with a good API that can be used across the libraries. Otherwise people will start implementing a bunch of versions of the same base functionality like search and node/neighborhood discovery with slightly different APIs and possible with incorrect logic. ---

I have done some work analysing my network with the igraph package to analyse my Org-Roam database. [Visualise Org-Roam Networks With igraph and R](https://lucidmanager.org/data-science/visualise-org-roam/) Igraph has a large collection of algorithms with code in R, Mathematica, Python and C++. Community detection (specifically the Walktrap or Spinglass methods) seem to work pretty good in knowledge networks. ---

@tecosaur and @danderzei Thank you for this thread. Very interesting discussion. Do you have any updates about this? I have two quick questions if you could help me with 🙂 - What’s the possibility of semantic analysis and directions? - I’m not a math/coding expert, could you help me to understand what is the theory behind linking nodes i.e. #Tags and or [[Links]] in .md files used?
