The above list shows some of the tasks related to language
that AI has come to deal with. All require a consideration of
both syntax(the word order aspect of grammar) and semantics (meaning).
The cornerstone to how computers will approach things is Chomsky's
notion of context-free grammar and normal form ((CNF). One builds things up
from the simplest - a noun verb combination - to more complex.
Using Python's natural language tool kit, the program is able to parse
sentences constructed from the given vocabulary. (News to me, French
now has the verb 'parser' to describe how computers propose syntactic
analysis). A terminal symbol is a word, a non-terminal symbol is a word species
such as noun, verb, determinative..., verbal phrase.
Program 0 reads simple sentences; program1 more complex but still has limits...
