I just started using RapidMiner. Although I follow the forum
and watch videos, there is a problem that I can't solve. I would be very happy
if you could help with this.
First, I want to find the frequencies of some words in an
80-90 page pdf file. I want to find out how many times certain words such as
'environment, government, business, business' appear in this pdf file. I find
the frequency of all words and even the frequency of a single word with the
filter option. However, I want to find the frequency of all 30 keywords.
Secondly, how many sentences are in this pdf file and how
many of these sentences contain keywords such as 'environment, government,
business, business'.
