Intro to syntax and parsing
POS (Parts Of Speech) are lexical categories which we attach to words, equivalent to gramatical classes.
Constituency
Constituents have a common behaviour, in this case, the noun phrases can appear before verbs
Context-free grammars
The constituents can be formalized.
These are production rules and are composed of non-terminals (noun, phrase, det, etc.) and terminal symbols (words or symbols in the language)
Symbol -> non-terminals and/or terminals
The rules are used for generation or assigning structure.
Constituents form higher-level constituents.
