Lab 9

Hi, Could anyone please share Lab 9 task solutions?

Please note that solving exercises H1-5 is part of the homework. This is the main reason why they are not uploaded. Similarly with lab 10, where you had to implement CKY and PCKY is one of the homework exercises.

You are encouraged to ask specific questions about the parts you are stuck with, though.

Thanks for the response. I didn't attend that lectures. Please only share solutions of Task W1-3 (warm-up tasks, not H1-5)

W1:

grammar = """
LEXICON Root
pack # ;
talk # ;
walk # ;
"""

compile_lexc(grammar, 'warm_up.fst')
draw_net('warm_up.fst')

W2:

grammar = """
LEXICON Root
! see how the continuation changes to the new LEXICON
! BTW this is a comment
pack Infl ;
talk Infl ;
walk Infl ;

LEXICON Infl
! add the endings here, without the hyphens
0    # ;
s    # ;
ed   # ;
ing  # ;
"""

compile_lexc(grammar, 'warm_up.fst')
draw_net('warm_up.fst')

W3:

grammar = """

This + the code snippet at the end of the lecture slides should give you enough ideas of how lexc works. Start solving H1-5 and post another question if you are stuck. Good luck!

Thank you very much.
