Hi,

I have 42 text files, each text file is a chapter from a novel. I am trying to visualize frequently occurring words in each chapter. How to approach this?

Also what other interesting problems I can solve with that dataset.

Thank you for the time and help.

    Hello ssk,

    you would simply read the files using a Read Document operator and then process it. In the end it's about the tokenize operator which counts the number of words.

    My friend and colleagure Marius pointed me to this tutorial for text mining: http://vancouverdata.blogspot.de/2010/11/text-analytics-with-rapidminer-loading.html this should really help you.

    If you have further questions, just post them here :)

    Best,

    Hi Martin,

    Thank you for the help.

    I have another question, I want to create a word cloud and show the frequently used word in it. How can I do that. The list of words from my 4 set of documents has 10,000 words in it.

    Thank you for the time and help.

    you mean some word cloud where the size of the word represents the frequency?

    If so,  I am not aware of any built in functionality. I guess it can be done using some javascript api.

    I've never used this webpage. Can't you just save your words as a tsv and upload it? Or should it be done automatically?
