[DESCRIPTION] The function takes a string input and returns a list of words in the input string that are not in the list of words in the file named "orksbi". The function uses the Python module "nltk" to perform the task.

Here is an example of the function's behavior:

* If the input string is "Hello World", the function will return the list ["World"] because "World" is not in the list of words in "orksbi".
* If the input string is "Goodbye World", the function will return the list ["Goodbye", "World"] because "Goodbye" and "World" are not in the list of words in "orksbi".

[CODE] Here is an approximation of the function's behavior in Python code:

import nltk

def f(x):
return [word for word in nltk.word_tokenize(x) if word not in nltk.corpus.stopwords.words('orksbi')]

Please provide the input strings you would like to test.

Please note that the function is case-sensitive.
