回复: 怎么样完成这样的检索?
There are several methods for this task without the need to write your own scripts. Here is one way to do it quickly:
Use WordSmith, AntConc, etc. to make a wordlist out of the text in question, then compare it with the existing wordlist (lemmatized or unlemmatized) to identify the words which are not in the second list. That's it.
Good luck!
