Good afternoon,

I was wondering, in question III of the hands-on about syntactic level and parsing,

how could we answer without drawing the CYK chart for each of the word sequence tagged?

Thank you very much for your time and answer

You mean, the one about accepting some tag sequence; that's it?

You have to check with the grammar rules :
  • first of all, the question is about a sentence; so it has to correspond to the top-level symbol `S`; so, from the rules, you need at least some verb (VP) somewhere;
  • Then, you can also see from the rules that you need even more: the VP cannot be made of a V alone, but requires some complement(s);
  • Then, looking at the NP rules, you see that there cannot be more than ONE Adj on the right of the NP (there can be many on the left of the N, but only one on the right).
Does it answer you question?
