Grammar theories : concerned with the concept of the writer / reader

( source ) 

My question is motivated by the concern of how to represent natural language in machines. (I am working on a broader model, of which this will be a part.) With regards to the semantics of sentences, my question comes from the following observation :

• Given, for example, (0.) "Red trees are bland.", the COMPLETE recognition of this sentence can occur to various degrees, for example :
• (1.) This is a sentence in the English language of 2025, which attaches a well-known predicate to a well-known subject, without any further context.
• (2.) It may be further noted that whomever made observation (1.) has the capacity to evaluate the context provided by the full sentence (1.) in addition to the original (0.) ... and this recurses furthermore as any entity which thinks (2.) may or may not be self-aware that it thinks (2.) etc. So we have 2.1., 2.2., etc. in this branch.
• (3.) Furthermore, there is the open question of what the further context of (0.) is, and it may be that (0.) occurred one of 3.1/3.2 etc. contexts ... whereas you and I know, it happened in (3.n) exactly, this discussion on Reddit.

So yeah, I was just wondering if grammatical theories had addressed these aspects of how a sentence is read, but I might have gotten off on the wrong foot if this is generally regarded as a semantic concern, not a grammatical one. That being said ...

... thanks so much for this pointer. I'm sorry for the late response, I have been crash coursing myself in the canon of linguistic theory on Wikipedia. It's been a bit slow as there seem to be dozens/hundreds of theoretical frameworks which aren't organised in a single structural taxonomy. Fun. Nature of fuzzy language, I suppose.

The particularly concepts which I have found to be most relevant to my question are :

• - 'focus' where, encoded information requires the sentence processor to semantically construe a number of possible contexts, and then to pick the right one
• - 'cognitive linguistics' wherein the use of language in humans is viewed as supervenient upon anatomical concerns ( reducing basically to information theory and processing )
