Re: Questions - meta-questions about knowledge representation

Hello everyone,

Hope this thread is still alive.

Good questions, indeed. Specially risen today in the hype era of LLMs, RNNs
and 'other' technologies that sometimes seems too complicated, even for
so-called easy examples.

The use of formal and symbolic logics, e.g. FOL, assures the coherence,
correctness, and evolveness capabilities of the axiomatic system, relying
in well defined and structured hierarchy of descriptive logic languages
well-stablisheds. As a branch of the semantic networks, these logics were
proven very useful to structure knowledge systems, orchestrate services,
and permit RNNs, MLs, DNNs, to learn on top of the produced knowledge,
information, and data.

Some examples are easy found on chatgpt, e.g. aws, azure cognitive
services, google knowledge-graph, etc.

But, maybe they are not enough to express the interactivity of knowledge,
principally when uncertain knowledge is concerned.

4) if you use google you may direct see its evidences, I suppose. They use
ontologies to interpret the user entry, then organize the output in
semantic categories, e.g. albums, sales, colors, etc. Also, KRR is also
very useful in NLP, due to the linguistic representation it offers.

My meta-level question are 2:

1) why there's so little speaking of KRR evolution traceability, patterns
of tracing graph evolutions;

2) theres a non-linguistic method to express knowledge?

best,
