In that section, 5.4, there is nothing that is compiler-technology 
specific.  The section "5. Parsing" is a bit misleading as "parsing" is 
going on at different levels.  This is abstract syntax (output of what 
might more conventionally be a "parser") to triples generated.

Maybe "Generating triples" or "Generating RDF from Turtle"

(the Turtle grammar doesn't require  LALR(1) -- at least I hope not and 
it is possible to write a Turtle grammar using LL(1) which is much 
simpler and what someone hand-writing a parser might use).

For now:
"with an LALR(1) parser" ==> "when parsed"

In the same section;

SPARQL is case-insensitive for everything except "a".
