New essay about labeled property graphs (LPGs) and RDF knowledge graphs. What’s the difference? open.substack.com/pub/jessicat...

I think this is my new favorite blog post/essay from @jtalisman.bsky.social: "Where Provenance Ends, Knowledge Decays" jessicatalisman.substack.com/p/where-prov... #datasky #dataBS 📚

Excellent breakdown of how the word "context" is currently being abused, what it actually means (in a given context) and how it relates to the current state of token economics. So many well researched insights and choice quotes by the author in this. Lengthy article but very much worth the read.

A ton of research went into this essay. Discipline is the ability to exercise taste and taste requires judgement. open.substack.com/pub/jessicat...

This context silliness is showing us how insane the AI industry is. Try to define the word in a room full of technologists and tell me how it goes 😂 open.substack.com/pub/jessicat...

Ontology Part I The Architecture of Meaning This essay is the first in a four-part series. I’ll break down concepts, bring clarity to what an ontology is and is not. I’ll share resources, standards, and help you get started modeling and building ontologies. open.substack.com/pub/jessicat...

When a model ingests carefully documented claims, it strips its provenance, l unattributed text,and replicates the exact mechanism by which historical knowledge has always been lost — only now it happens millions of times a day, across every domain. open.substack.com/pub/jessicat...

It’s here: A Practitioner’s Guide to Taxonomies, Part III Formalizing with SKOS This essay and tutorial has all you need to build a validated, RDF SKOS taxonomy. Happy building! open.substack.com/pub/jessicat...

Foundation Capital’sContext Graph article, published Dec 22, plagiarized my four-part process PKM essays published between Dec 3—Dec 18. Counted three more articles by same group: also plagiarized. I’m a librarian so of course I’m calling it out 📚 open.substack.com/pub/jessicat...
