Glossaries and ontologies: Definitions of terms in data

In the wonderful talk "Design in Practice", Rich Hickey talks about how important an up-to-date glossary is in the design process.

I have a similar view, and see something like "Business Knowledge Blueprints" as an important foundation for business applications and especially for (enterprise) knowledge graphs.

event semantics

:Brutus :stabbed :Caesar → But when exactly?

Mostly a fully automatic translation through deepl - I started to think about this in german...

Or Reify vs. RDF Star. Or Davidsonian event semantics for modeling.

I think I got the above example with Caesar from John Sowa's "Knowledge Representation", that I unfortunately lent and never got back, so the exact page reference is missing.

Explaining OWL: use 'set' for 'class', it's more precise and less likely to be confused with OO classes

Today I listened to the workshop "Democratize the Knowledge Graph and Concrete Tooling Requirements" by Adam Keresztes at the 2023 Knowledge Graph Conference in NYC.

Different people there emphasized the difficulty of explaining the difference between classes and instances to non-ontologists.

Which had me reflecting on how I work with this terminology, and I found that I tend to use 'set' instead of 'class'.

Knowledge Graphs

Starting ontology creation from existing taxonomies

Yesterday I was at the Connected Data Meetup in London, and listened to a presentation advocating taxonomies as starting points for ontology creation, by Madi Weland Solomon.

She didn't discuss this at length, so the following is my understanding, all errors and bad ideas are mine :)

Business Knowledge Blueprints

Business knowledge blueprints are a powerful tool for identifying the basic structure and requirements of a business. By working with a coach or facilitator to create a business model blueprint, organizations can gain a clearer understanding of their business model and how it fits into the broader market.

RDF, OWL, and SHACL are powerful formalisms that can be used to express and analyze the results of a business knowledge blueprint coaching or workshop. These formalisms allow businesses to represent and manipulate data in a structured and meaningful way, enabling them to make more informed decisions about their business model and strategy.

Logic, Semantic and Data Modeling

Logic and semantics play a critical role in data modeling, as they help to structure and organize data in a clear and meaningful way. By using logical and semantically rich data models, businesses and organizations can better understand and utilize their data to make informed decisions and drive growth.
