I'm trying to tokenize a huge document (wikipedia) (so that I can convert the document to word vectors). I want to convert the giant char array into a numeric array of token IDs (indexing into a dictionary I have) in word order. I was able to write code for this using for loops of regexp()'s, but it's taking days and days to run. I see that tokenizedDocument() might be a good alternative, except that I can't figure out how to get the document back as a list of numeric token IDs.
Has anyone successfully tokenized a document in this way? If so, how?
Thanks!

For example, 'a cat ran ...' should be converted to [1,49,34,...] (where cat is the 49th word in the dictionary, etc).

Hi,
You can use "tokenzedDocument" to tokenize your document. The actual performance will be impacted when you will assign rank number to each token. I would suggest you to use map containter for the purpose.
