Hello all,

I am on the last page of the second chapter of the NLTK Book. On page 73 theres a try me now about verbnet. I tried but are unable to access it.

>>> nltk.corpus.verbnet

Is there any reason as to why?

Hi Max,

What problem exactly do you have? I can only answer your “why” question: The nltk comes with about a hundred corpora, almost none of which will you use in a given session (and most of which you will never use.) The corpora are provided as stubs through the “LazyLoader” class. When you try to actually use them, they will be transparently loaded for you. (Or just call the .ensure_loaded() method).

You’ll also need to download the verbnet data using `nltk.download()`, if you haven’t done so yet. Then just go on to use the corpus.

Alexis

Hello Alexis,

Thanks for writing. It is more of a confusion than anything. I worked all the way through chapter 2 of the NLTK book with no problems following the content. On page 73 though, there is tip that says that verbnet can be accessed with the code:

>>>nltk.corpus.verbnet()

Except, when I run this it throws this strange error:

I did in fact download verbnet because I checked several times and I checked the documentation for verbnet. So this is where I am stuck.

That’s not an error, it’s a text representation of the unloaded corpus object. (And you’re clearly typing nltk.corpus.verbnet, without the parens; otherwise you’d really be getting an error).

Just use it like any other nltk corpus: Import it, then find out what methods it has and use them. (If the documentation you read didn’t do it, try `help(nltk.corpus.verbnet)`.

Update:

I can run all the code on:

http://www.nltk.org/howto/corpus.html#verbnet-corpus-reader

So it's probably nothing that I have to worry about. I guess I was more curious about the message than anything. Anyways, I will probably move on to the exercises.

-Thanks for your help Alexis! :)
