[NLTK]Extracting keywords from text files using nltk 16 Years Ago by dilipkk Hi, I am looking for a tool in python which can build a model based on some set of training documents with manually assigned keywords. And then it uses that model to extract keywords from new documents. I want to know whether using NLTK can I do this?
