Summary for how logseq should build a world knowledge graph →
#

Logseq wants to build a World Knowledge Graph. Here are the steps I think they should take:

→
#
>

Allow users to build knowledge graphs with their notes.

→
#
>

I have a rough proposal for how to do this in a way that is similar to Joel Chan’s Discourse Graph here: Building a knowledge graph in Logseq

→
#
>

Allow users to create a mapping from their knowledge graph to a general ontology.

→
#
>

This could be just like Discourse Graph’s default ontology (types: questions, claims, evidence, etc. relationships: supports, opposes, informs, etc)

→
#
>

Alternatively, there could be a more general knowledge graph ontology provided (using existing work with RDF, for example).

→
#
>

Likely it will make sense to allow for multiple ontologies to exist as “translators” for users’ knowledge graphs

→
#
>

Side note: I’m thinking about category theory and considering knowledge graphs to be categories and translations between them to be functors.

→
#

Make it possible to publish a subset of your knowledge graph and integrate other knowledge graphs into your own

→
#
>

Once you’ve translated your knowledge graph into this general ontology, anyone else who also has a translation into that ontology should be able to integrate the notes from your knowledge graph into their own.
