Robert R.

Are you formally working on a project asking these questions? What are your reasons for asking the questions? These sorts of questions, including your other post about 'semantic layer' are within some of my specialties, such as conceptual analysis, semantic analysis, clarifying concepts, terminological analysis & development, etc.

My reply to your similar question on 'semantic layer' has relevant input.

In general, the questions and answers cover a very large amount of content: common-sense understandings, academic philosophy, linguistics, computer science (e.g., formal semantics), etc.

Consider looking at dictionary definitions as a start, and compare to others in other material, from distinct disciplines and organizations.

As mentioned in my other reply, I have in-progress personal projects cataloging and comparatively analyzing concepts and associated terms relevant to these questions, including terms with 'semantic' in them. As well as raising meta-level questions questioning some aspects thereof.

In one of my publications, I specifically mention--in the context of AI and semantic modeling--the aspect of meaning as a human phenomena. But the historical and philosophical literature is replete with relevant discussion.

I've formally studied philosophy and related disciplines, by degree and otherwise. So I can help if there is some project here. My content from 5 above may be relevant.

I'm available for formal work collaborations (i.e. hire). So I can offer that. Please contact me or schedule a meeting at this link.
