Reasoning Under Imperfect Information

TL;DR Expert knowledge is more than facts, rules, procedures, or recipes. Its greatest value often appears when the normal procedure runs out: an unfamiliar failure, an ambiguous observation, or a situation for which no one has already written the answer. Experts draw on a mental model of how the world works, form competing explanations, predict … Continue reading Reasoning Under Imperfect Information →

Reaching from the Realm of Information into the Realm of Knowledge

This blog is based on a "deleted scene" but is also an update to the technology mentioned in my book, Semantic Webs of Meaning (available on Technics Publications  and Amazon)—specifically Chapter 8 on scaling query performance for a knowledge-graph deployment. In that chapter I did not talk about the contribution a performance-oriented semantic layer (ex. … Continue reading Reaching from the Realm of Information into the Realm of Knowledge →

Symbols Travel, Meaning Is Rebuilt

TL;DR (Sort of) Since this TL;DR is relatively long for a TL;DR, here is the elevator pitch: Humans and LLMs live largely in rich, subsymbolic internal worlds. Knowledge graphs live in an explicit, serialized world. Intelligence increasingly depends on moving between the two—and continually checking that what was reconstructed still corresponds to what we meant. … Continue reading Symbols Travel, Meaning Is Rebuilt →

The Art of Crafting Competency Questions for Knowledge Graphs

Applying self-service BI concepts to knowledge graph development. This blog is from the “deleted scenes” of my book, Semantic Webs of Meaning, available on Technics Publications and Amazon (mostly Chapter 10). It is also a continuation of the competency questions discussion begun in Where Should an Enterprise Knowledge Graph Start? Competency Questions: TL;DR Competency questions … Continue reading The Art of Crafting Competency Questions for Knowledge Graphs →

Where Should an Enterprise Knowledge Graph Start?

I recently became aware of a stance on how to begin a knowledge graph endeavor that is somewhat contradictory to what I prescribe in Semantic Webs of Meaning. This is an important point to clarify. Here is the bullet-point summary: Different Stance: Do not infer what the ontology ought to be merely from the structures … Continue reading Where Should an Enterprise Knowledge Graph Start? →

Trailer for My New Book: Semantic Webs of Meaning

Update August 25, 2026: The supplemental GitHub repo for the Semantic Webs of Meaning is live. The supplemental repo has these main purposes: Post material that is too down into the weeds for the book (ex. install instructions, full appendices, code samples, and tutorials) but is mentioned there. Enable me to expand upon and/or clarify … Continue reading Trailer for My New Book: Semantic Webs of Meaning →

Explorer Subgraph—The Dynamic Cartography of Relation Space

Abstract This blog introduces the Explorer Subgraph, a navigational knowledge structure designed to support System ⅈ (the ⅈ as in the imaginary number). I introduced System ⅈ a few weeks ago in my blog, System ⅈ: The Default Mode Network of AGI. The Explorer Subgraph is a background, always-on layer of intelligence that operates below conscious … Continue reading Explorer Subgraph—The Dynamic Cartography of Relation Space →
